Hey everyone, the cause of the square waves loosing definition and the rise and fall times not looking linear is a mistake that I made by not disengaging the bandwidth limit. This is not a problem with the scope.
learnelectronics, regarding your first update about the square waves going to pot, show me. After watching this video the Hantek came out looking much better in a number of comparisons. Square waves went to hell on the Siglent when on the Hantek it was quite recognizable, it could not come up with frequencies when the Hantek could, and the vertical display on the Siglent reduced considerably when you changed from 20mhz to 30mhz, but not on the Hantek. And somewhere the Siglent did not even trigger on something like a 10hz signal. But your comments were continually “Good“ and “No problem"? And you gave it a big thumbs up? You should have investigated the reason for the odd results and redone the video instead of rushing to be first. I know the Siglent can do far better, but I would never know it from this video.
Wish I'd seen this comment before I watched the video. Spent time trying to find others with the problem. You should have redone the review as stated. It is pointless in its current format
and so what, most people don't read the comments section. you should remove the video or post something actually in it.... giving them a bit of a bad rep IMO.
For those not happy with the Siglent showing of a bad square wave. There is a fix for this that is well documented online. There are two unoccupied pads on the input section of this scope. The manufacture forgot to install two compensation capacitors and will need a modification of adding of the two missing 3.9pf capacitors. The procedure takes less than an hour to do. This is only effected on early serial numbers that contain a BA Serial numbers with a BB do not have the issue and the production line added those trim capacitors during production. Siglent will send them to you free of charge if you request them.
OK I was going to buy this unit to check 300 Hz signal on a test tape for a cassette tape calibration and was wondering if it’s good enough without having to fix the capacitors to do such a thing
Just got myself one for Christmas! As a Ham radio operator, it's extra handy because the frequency counter is sensitive and works correctly well above 200Mhz!
Good to know, Robert. I have a Rigol that never displays accurately. It’s always off by a couple thousand Hz. Still a good scope. I just added this to my other bench and I’m looking forward to getting it.
I think you have missed that the Siglent's frequency counter only seems to count fine, when there is more than one full period on screen. In the cases that it failed to show the frequency, too little of the wave was shown on the screen to have the Siglent show a frequency.
Yes like tektronix. But you can see the hardware frequency counter (plus it has a better resolution) to the top right of the screen. This one is showing even when the wave is not complete
Nice video, I really learned a lot. I just picked up a siglent 1202x-e and it was the perfect tutorial really got me off the ground kinda learning to fly... your vocal cadence was perfect i didnt have to rewind 10 times, it was clear and succinct paitient just right. Thank you also for taking the time to post the "debug" information down here in the comments, saved me a lot of time being a nube figureing it out myself. I also now have a basic understanding of the nomanclature, the layout, basic bench testing every nob and button, and the sub menus wave patterns frquencies im happy as hell peace brother i suscribed to your channel with a lot of i cant wait to watch the rest of the videos you posted ~Deez Nuttz
Adjust knob going up clockwise and down counterclockwise is standard for consumer devices (ex volume, or menu navigation with knob on most devices other than ipod classic)
When you were checking the square wave response, you should have terminated the scope end into 50 ohms. 18pF has a reactance of 295 ohms at 30Mhz, and when in parallel with 1M ohm... it will degrade the waveform.
Exactly. The generator is likely 50 Ohms as should be the coax to prevent reflections and ringing. Use a 50 ohm in line scope term as this one has no termination option.
FWIW, got this scope this weekend, decided on it for the serial decoding feature mostly. Couldn't find any vids or decent instructions on how to get it running. This vid is good at showing the feature itself, but this isn't about how to set it up. It's very easy for a noob like me, so I can give you some specific actions to take. I've been only playing with I2C debugging - here's the methodology I follow. Turn it on. I'd suggest hitting default, to reset from wherever you were before to ground zero. Set both probes on 1X. Attach grounds wires to BOTH of them, connect them to the common ground in your circuit. Connect one probe to SLC, other to SDA. Now you may or may not see the signal, most likely it'll be set to auto trigger, so it'll probably flash a wave every 500ms or so depending on the communications going on, maybe faster. Hit the auto setup button, it'll hone in on the signals for you - you should be between and 3 and 5v depending on the logic voltage, and your probes will show 200mv or 500mv or so. Now you can just setup decoding and fine tune from here. Hit decoding button, set channel 1 for SLC and 2 for SDA under the "signal" menu which ain't ideal (channel 2 may not be on after hitting default mind you, hit the 2 button to change it). Pick I2C. You're setting up "decode 1" right now mind you, not sure what that means. "display" turn it on. Hit next page (page 2). Click "list" - pick decode 1, and you're good for the options. You'll probably see no decoded messages at this point, but depends on the actual communication and the horizontal (period?) setting currently set. Set trigger to normal, and adjust the knob to get around 1ms, or 500us. If you're experiencing communications every couple seconds and not miliseconds, you'll probably need to up that to 2 or 5 seconds. Maybe you'll see some decoded messages. If you chose ASCII on menu 1 you can even read the message like a human. I don't usually see them yet, till I zoom in. So do that, zoom, and use the position knob to hone in on sections. If you make the time period longer with horizontal, you'll see more messages listed. If you're zoomed nicely you'll see the messages on the bottom, in the little DNA chain looking bubbles you'll see the full message in there, zoom in and out, pan around and suit to your liking! Want to correct me? have at it! :)
19:08 The oscilloscope on the top is a HANTEK probably the DSO5202P 200MHz, not sure why is being hide, looks better than the siglent specially it keeps reading on the 10MHZ input.
The reason why the Siglent can not lock onto a signal is simple; it can only tell if there is a full cycle on the screen. I would know as I own one. If the signal is off the screen, why would I want to know what the frequency is? I think it was actually a smart decision by them to do this. The Hantek seems to be able to lock a signal no matter what is on a screen and to a user like me, that is also useful but not as much. To anyone on the fence about the Siglent, I totally recommend and use it daily!
One can see how much better the Digital Trigger is on the Siglent oscilloscope! No movement compared to the top scope which is shifting quite a bit back and forth. The other scope must have an analog trigger.
"Nice and heavy, nice and thick". Those are specs I had never considered as important in selecting a scope. Well, maybe the weight if I had to drag it around a lot but my scope stays on the bench for the most part.
Hi everyone, I need some good info witch to buy SDS1202X E OR Hantek DSO5202P . What do all think. I have about 370 pounds to spend. so could do with same help. Thanks Yannis.
This scope seems to be a pretty good deal. As a hobbyist (Arduino projects and such things) i've started with a cheap diy DSO 150 scope kit and now i'm beginning to look for a serious one. The screen and UI seems to be pretty clear, the free licenses for decoding I2C and other things seem to be rare in that price range and overall it doesn't seem to have serious flaws - that's at least the impression I got from watching multiple reviews. 2-Channel should be enough for a hobbyist like me or?
That was a good review, very interesting and relaxing, why relaxing? I watched Dave Jones review the same scope and was a nervous wreck at the end of it. good scope I reckon..
David Price I'm glad you liked the video. it is an excellent scope at a good price. What really makes it nice is that Siglent answers emails and phone calls. They are a small company that cares what customers think.
very nice demo... 😊 i wish there was a uart modbus rs485 serial decoder demo. i can get ok results however some pointers would be great for learning 😎 thanks
Thanks for the review. I'm thinking of replacing an old Tektronix scope that's starting to fail. Unfortunately, I no longer have the money to get another Tektronix scope so I've been looking at these more affordable scopes. I work mostly on audio equipment including a lot of vacuum tube stuff. Does anyone know if this can handle the high voltages (up to 700VDC) used in this type of electronics?
Thank you for great review! Like I understand on the 25:24 this SDS1202X couldn't recognize the waveform correctly? Because you said there square shape wave but I see saw shape.
I have a question. I'm learning all this newly, and the rule has been you would want a scope that can do five times the bandwith that you're measuring, so on a 200 mhz scope, why do they lose "waveshape/verticality" at 5,10,etc mhz? Isn't the idea that since the scope is more than five times the bandwidth of those signals that they should be quite good in terms of wave shape? For example when a square wave starts to turn into a sine wave at 10 MHz? Great video by the way
@@Urbanhashhustle No CD, don't have a CD player anywhere anyway... but picked this up last weekend, have the serial decoder working great, no square wave issue after calibrating the probes.
Hi, i bought that oscilloscope, but when i hook the probe on the test pin, press auto-setup it show me a square wave and that is ok, but after same random seconds the trigger lost and rehook the wave istantaneally...it's normal or there is something of strange?
Hi i have the earlier Siglent SDS1102DL+ (EasyHunting) 100mhz 500MSa/s oscilloscope, i mainly use it for ssb cb radio calibration, is the Super Phosphorus display a lot quicker for RF ? PeaceFromOz
Sure looked to me like you were showing that it did not track a 30 Mhz square wave as well as the other scope. I'm wondering if the bandwidth rating of the scope is not as important as the sampling rate, but were both of those scopes 1G/s?
Wasn't that meaningful of a test, a 30 MHz square wave will have frequency components way higher than 200 MHz and that's what was being attenuated. Better to just see at what frequency (expected around 200 MHz) a sine wave starts being attenuated. So it's not really an issue, it's a 200 MHz scope.
as far as the "backward" rotating knobs go, I think they're just fine. Imagine those indications on the screen populated around the knob itself, in the same order, as if that menu were physically printed on the panel around its very own dedicated knob. Now imagine that highlighted position as an arrow pointing to the selected physically printed function. The functionality now translates almost perfectly for those being used to my old-school CRT Tektronix and HP oscilloscopes where there were no on-screen menus.
Hello Paul, Would appreciate a direct comparision btw. this Signlent and the Owon TAO3104a that you showed in the recent video. Trying to choose between those two. Thank you, Catalin
In 27:41 you say it's a 20(!)MHz scope when, in fact, it's supposed to be a 200 MHz scope. But when I saw how amplitude and shape deteriorated significantly between 20 and 30 MHz square wave input, it DID act like a 20 MHz scope. But you wrote below the bandwidth limit of 20 MHz was still active in the video, so I guess this explains it.
@27.44 you tell its a 20 mhz scope. .... isn´t it a 200 mhz scope as it says on the front of the scope texts ? GRAET revieiw. i feel like buying it now
My scope would NOT come out of screensaver mode, not even power off worked. Did it 4 times when I got it several weeks ago. This week it seems to be working ok. Has anyone else had this happen ? Also noticed your cal date is same as mine and 3 of the pieces used for calibration are passed due. Hopefully its a typo ? TNX for the video ! 73 N8AUM
Thanks for watching and commenting. Please get in touch with Siglent and let them know of your problem. info@siglent.com They are a small company and like to address problems head-on.
Hello. We had a printing error with the calibration certificates. Contact us at info@siglent.com for more information about both issues and we will assist you.
That is an amazingly full featured scope for less than $400! I wish I have serial decode on my Rigol DS1054Z. I know you could buy that feature or hack it, but I'm too cheap and unwilling to pirate. :-) Thx for the review.
This is an old thread but I have a question. Do you know if this has a DMM display? I worked with a scope years ago that had a DMM display area at the bottom of the waveform area. It showed Peak, Avg, and DC volts if present I numeric format. I loved that scope.
Yes it does have DMM AC Voltage p-p; rms; average; etc showed at the bottom of the screen. You can display four different values simultaneously from a very long list like frequency; period; rise time etc.
Nice video Paul, but I think you missed a great opportunity to show deep memory advantages. At times when you switched from low frequency to higher frequency. There are times when the Hantek loses signal and the Siglent is solid. If you were to use the zoom function, I think the Siglent would have given a nice picture of the wave while the Hantek would have displayed something strange. For instance I think at 19:48, 20:32, and the one at 24:30 was the most glaring example. I used to hate Digital scopes because of what I called digitizing. The Siglent deep memory has the bits to sample that amount of data. So at 24:30 the Hantek is showing what looks like low frequency because it is sampling just parts of the 5MHz signal while the Siglent easily captures the samples and stores them in deep memory - preserving the wave shape.
Sir. Thank you for this video as I have this scope since getting into arduino last year. I was wondering if you could help me. I'd like to use my scope to monitor the voltage drop on a cr2032 graphically is possibly. Thank you. P.S. I haven't used it in awhile!
i wonder why it didnt trigger properly at freqs under 200Hz. i think the guy from eevblog mentioned that the scope under test he had would switch to rollmode when you set the ms/division thing higher than a certain value. could that be the case here too?
I think it is a software frequency counter. Adjust the horizontal control. It needs to display a couple of full waveforms to be able to calculate the frequency. Most scopes are like this.
Thanks for reply, Siglent is little out of budget but one thing Hantek 24K record memory and Sigelent 14MB. What is your expert opinion on this record memory and its impact on usefulness.
@@Starcraftowns99 i have ancient ananlog since 1980s they are still smooth throughout time division scales. but i guess all digital oscilloscopes can not display smooth music signal slower than 1ms = 1khz. i did try to display subwoofer signal which are lower than 150hz, 5ms on time division of digital oscilloscopes is crappy.
i have this scope, I bought it for calibrating a few synths and have had no problems. However, I was designing a simple circuit with a UJT transistor (2n2646) as a simple oscillator and I wanted to see its resultant waveform. I was able to do that and all looked good, but the scope constantly goes into 'acquiring' mode and takes up to 30 seconds to refresh. It made using the scope really difficult as it couldn't keep up. Has anyone got any ideas as to why this is happening or what I maybe doing wrong?
@@Pedro_Takahashi_Gunderson_Jr hi Pedro, yes kind of. The frequency was too low for the scope to capture. If you press the Roll button it will draw it in real time that helps somewhat. Also, using Auto my scope couldn't lock onto the waveform I was interested in, there was a lot of other DC noise in the signal, someone suggested reducing the bandwidth of the scope to effectively filter out the frequencies I wasn't interested in. Through a combination of these steps I was able to display the waveform I was looking for.... LFO's in guitar effects and synths are slow, when heard as audio you can hear them go up and down, so it kind of makes sense that you need a bigger capture time (time division) to display them, but then the scope can't keep up. I think that's the essence of issue in this situation, but I could be wrong, I'm learning still too.... I learnt the above from posting to a guitar effects builders forum.
@@silvertongues2 Thanks a lot for the response. I was trying to look at the charging and discharging of a capacitor and the roll mode allowed me to do that. I want to get into designing audio amps, analog synths and guitar effects. so far, I've read Make: Analog Synthesizers, which wasn't comprehensive enough for someone to get into detailed design, and I'm currently reading Designing Audio Amplifiers by Bob Cordell, which will take some time to get through. what approach have you taken to learning audio circuit design?
@@Pedro_Takahashi_Gunderson_Jr the same books, plus a few others. I've been building a lot of schematics and then using the books and forums to understand what is happening, and then I've progressed to making adjustments, and combining blocks of circuits to make my own design. And then I've tried to drill down into each block to understand how it works. I'm up to a point in which I know what parts are needed, and which components influence the outcome, but only high level understanding of what's happening at an electron level.... but, I guess the impression that the more you build (and debug) the better your understanding becomes.....I also found a few guys who I can call upon as mentors if I get stuck or have any questions. One of those guys is a trusted synth repair guy I've used, and the other is someone whose an active member from a facebook guitar pedal forum.... If you can find the right facebook group they're invaluable. Look up Guitar Pedal Builders group. People post schematics, and some really experienced guys offer help. (also, using LTSpice to review a circuit, rather than an oscilloscope, is quick and easy once you're learnt the software, it's what the pro's do when prototyping).
@@silvertongues2 thanks for all the info. I guess I'll just keep plugging away at it. spice programs are invaluable, but it seems tedious trying to input all the transistor characteristics. it's just another thing I need to do more of and I'm sure it will become easier. I'll look into the facebook group, it sounds very helpful. thanks again and good luck!
My current DSO is a 20 year old HP 54645A. It has a menu setting that allows a choice of Left, Center or Right for the Trigger zero reference position. Most of the time it is set to the Left because I'm only interested in seeing waveform after the trigger event. The Trigger zero reference position stays put regardless of change in Time base setting. I have been informed the SDS1202X E has the same ability. I have not been able to find confirmation in the operator's manual. May an owner of the model please confirm? Once one has become aware of this ability, DSOs that don't have it are unbearable to use.
learnelectronics for the price i was gonna pick one up. but i do a lot of audio. i frequently test using 40hz wave. so... thats a fail. lol what scope would be recommended?
even the 200hz model is only about 330! lol so thats a good imo. i have an idea how to do the hacks to unlock the 200hz but ehh id rather just get the 200 model and call it a day but thanks. checking out the video now!
Suresh Lingabathina Babu My Hantek is a 5072P. It's a 200MHz, 2 channel. Here is a link to a video: th-cam.com/video/JzfYSBwshyo/w-d-xo.html As for your choice...if you want serial decoding pick the Siglent.
Suresh Lingabathina Babu I have no experience with the Hantek scope you are considering. The two Hantek scopes I own are excellent products. That being said, if the Siglent is in your price range, that is the one I would choose.
Bonjour, Ceci arrive quand il y a beaucoup des boutons et encore d'avantage sur chacun d'eux des fonctionnes associées. A moi aussi il m'arrive par fois de se perdre dans la jungle des possibilités Rien de grave mon oscillo il y a une bande passante de 340 MHz !! avant qu'il commence a atténué un petit peu et a ses 50% il arrive à 390 MHz pour un telle prix c'est un ЗМЕЙ ZMEÏ en bulgare = Lamie en français ( ou Dragon ) Merci à vous et bien des choses pavlin
I made a little picture to make screen menus translate to knob rotation direction easier. This is what a dedicated knob would look like. drive.google.com/file/d/1PXBTWgBZWeUReg0Cz2q7VI_aWvScHPd3/view?usp=sharing
I included labels on both the right and left hand side, so you can see the direction the knob would rotate depending on the label locations with respect to the knob.
А нафига он щас нужен, если щас нету таких устройств, где можно было бы подпаять какие-нибудь кондёры или резистеры?! Ща всё на микрухах сделано и на малипусечных усройствах, которых паяльником не подпаяешь.
At 21:03 besides the Siglent losing HALF of the displayed amplitude, (bandwidth LOSS), YOU evidently forgot? to adjust the trigger level to lock in the waveform.... Additionally, the Hantek displayed rock solid frequencies where the Siglent did not display shit.... This video is the deciding factor in my making a Hantek DSO2D15 purchase.... WHY spend MORE for CRAP??

just bought mine from Amazon will be my first scope but i don't even know how to use it. haha

That was a good review, very interesting and relaxing, why relaxing? I watched Dave Jones review the same scope and was a nervous wreck at the end of it. good scope I reckon..
David Price I'm glad you liked the video. it is an excellent scope at a good price. What really makes it nice is that Siglent answers emails and phone calls. They are a small company that cares what customers think.
Thanks Peter, and that circuit you helped me with (LM741 oscillator) was my first sinewave, I appreciated your help greatly..
Believe it or not I bought a Siglent today, an older model (SDS1052DL),
best value I could find $328 AUD.. Cheers.
@@learnelectronics on contarily, they never reply me, both international and europe agencies.
Yeah that Aussie's voice drives me nuts, he sounds like he was kicked in the nuts every time he talks.
Picked this one based on your review. Great instrument at least for a hobbyist like me
The Siglent is a great scope. I hope that you enjoy it!
very nice demo... 😊 i wish there was a uart modbus rs485 serial decoder demo. i can get ok results however some pointers would be great for learning 😎 thanks
thanks im now baying this scope
I have the Hantek scope like you have.. However, all the encoders stopped functioning.
Thanks for the review. I'm thinking of replacing an old Tektronix scope that's starting to fail. Unfortunately, I no longer have the money to get another Tektronix scope so I've been looking at these more affordable scopes. I work mostly on audio equipment including a lot of vacuum tube stuff. Does anyone know if this can handle the high voltages (up to 700VDC) used in this type of electronics?
Thank you, great review.
Thanks for the video
I see Yan's name on all kinds of Siglent equipment reviews. I think we can all agree, that is one (pffff) busy Wang....sorry, not sorry.
Just got one, Yan's still the one man band apparently. or it's bullshit ;)
Really thorough review!
Thank you for great review! Like I understand on the 25:24 this SDS1202X couldn't recognize the waveform correctly? Because you said there square shape wave but I see saw shape.
"HOLY SHIT JIM I GOTTA SHOW YOU THIS WAVEFORM!"
I have a question. I'm learning all this newly, and the rule has been you would want a scope that can do five times the bandwith that you're measuring, so on a 200 mhz scope, why do they lose "waveshape/verticality" at 5,10,etc mhz? Isn't the idea that since the scope is more than five times the bandwidth of those signals that they should be quite good in terms of wave shape? For example when a square wave starts to turn into a sine wave at 10 MHz?
Great video by the way
Great excellent review
I got this scope since yesterday. My second, but first that class scope. I am so happy :) Now I need to learn its functions :)
I just got mine from amazon, but it didn’t come with a CD how about you ?
@@Urbanhashhustle No CD, don't have a CD player anywhere anyway... but picked this up last weekend, have the serial decoder working great, no square wave issue after calibrating the probes.
So why the Ethernet jack on the back? It;s active, with the unit claiming an IP address through DHCP, can it be used for anything?
Hi, i bought that oscilloscope, but when i hook the probe on the test pin, press auto-setup it show me a square wave and that is ok, but after same random seconds the trigger lost and rehook the wave istantaneally...it's normal or there is something of strange?
Doesn't the siglent have a hardware frequency counter?
True in the upper right corner.
Hi i have the earlier Siglent SDS1102DL+ (EasyHunting) 100mhz 500MSa/s oscilloscope, i mainly use it for ssb cb radio calibration, is the Super Phosphorus display a lot quicker for RF ?
PeaceFromOz
Do you still use this scope and how do you like it? Nice video.
Sure looked to me like you were showing that it did not track a 30 Mhz square wave as well as the other scope. I'm wondering if the bandwidth rating of the scope is not as important as the sampling rate, but were both of those scopes 1G/s?
+gazalaem It's a nice scope. I like my Hantek better.
Wasn't that meaningful of a test, a 30 MHz square wave will have frequency components way higher than 200 MHz and that's what was being attenuated. Better to just see at what frequency (expected around 200 MHz) a sine wave starts being attenuated. So it's not really an issue, it's a 200 MHz scope.
as far as the "backward" rotating knobs go, I think they're just fine. Imagine those indications on the screen populated around the knob itself, in the same order, as if that menu were physically printed on the panel around its very own dedicated knob. Now imagine that highlighted position as an arrow pointing to the selected physically printed function. The functionality now translates almost perfectly for those being used to my old-school CRT Tektronix and HP oscilloscopes where there were no on-screen menus.
if the knob were located on the other side of the screen, the left side, it would make perfect sense to make it rotate the other way.
Hello Paul, Would appreciate a direct comparision btw. this Signlent and the Owon TAO3104a that you showed in the recent video. Trying to choose between those two. Thank you, Catalin
In 27:41 you say it's a 20(!)MHz scope when, in fact, it's supposed to be a 200 MHz scope. But when I saw how amplitude and shape deteriorated significantly between 20 and 30 MHz square wave input, it DID act like a 20 MHz scope. But you wrote below the bandwidth limit of 20 MHz was still active in the video, so I guess this explains it.
Eevblog has cranked it up to 300 MHz with no issues. The 200 MHz test is for the bandwidth at 3db like all scopes.
@27.44 you tell its a 20 mhz scope. .... isn´t it a 200 mhz scope as it says on the front of the scope texts ? GRAET revieiw. i feel like buying it now
My scope would NOT come out of screensaver mode, not even power off worked. Did it 4 times when I got it several weeks ago. This week it seems to be working ok. Has anyone else had this happen ? Also noticed your cal date is same as mine and 3 of the pieces used for calibration are passed due. Hopefully its a typo ?
TNX for the video !

Thanks for watching and commenting. Please get in touch with Siglent and let them know of your problem. info@siglent.com They are a small company and like to address problems head-on.
Hello. We had a printing error with the calibration certificates. Contact us at info@siglent.com for more information about both issues and we will assist you.
It seemed to be rolling off at about 30MHz yet the 'scope is advertised as 200MHz. Please explain.
He made a mistake. He left a note telling he forgot to turn off the frequency filter.
Does the USB and Ethernet port on the back give you any features beyond what you can do with the panel controls?
rjstoneus not really, external control, data logging mostly
I am.on my second return to amazon. I keep getting scratches on the screen....
That is an amazingly full featured scope for less than $400!
I wish I have serial decode on my Rigol DS1054Z. I know you could buy that feature or hack it, but I'm too cheap and unwilling to pirate. :-) Thx for the review.

This is an old thread but I have a question. Do you know if this has a DMM display? I worked with a scope years ago that had a DMM display area at the bottom of the waveform area. It showed Peak, Avg, and DC volts if present I numeric format. I loved that scope.
Yes it does have DMM AC Voltage p-p; rms; average; etc showed at the bottom of the screen. You can display four different values simultaneously from a very long list like frequency; period; rise time etc.
Hi , Anybody know how to use it with tube amplifiers gear?
Is x10 probe enough? Or need x100 probe?
If yes, with x100 will suite to this scope?
Hi Paul,
What the covid is ; y squared c
as always nice video's

How many world premieres does this scope have?
Is anyone familiar with defective units with BA in the serial number?
can you use it as a DMM?
Nice video Paul, but I think you missed a great opportunity to show deep memory advantages. At times when you switched from low frequency to higher frequency. There are times when the Hantek loses signal and the Siglent is solid. If you were to use the zoom function, I think the Siglent would have given a nice picture of the wave while the Hantek would have displayed something strange. For instance I think at 19:48, 20:32, and the one at 24:30 was the most glaring example. I used to hate Digital scopes because of what I called digitizing. The Siglent deep memory has the bits to sample that amount of data. So at 24:30 the Hantek is showing what looks like low frequency because it is sampling just parts of the 5MHz signal while the Siglent easily captures the samples and stores them in deep memory - preserving the wave shape.
You are right
Sir. Thank you for this video as I have this scope since getting into arduino last year. I was wondering if you could help me. I'd like to use my scope to monitor the voltage drop on a cr2032 graphically is possibly. Thank you. P.S. I haven't used it in awhile!
If you use one of the Arduino's analog input you can monitor your battery easily.

i wonder why it didnt trigger properly at freqs under 200Hz. i think the guy from eevblog mentioned that the scope under test he had would switch to rollmode when you set the ms/division thing higher than a certain value. could that be the case here too?
fredlllll yes, I think so. it has some quirks... those ugly square waves at RF frequencies...😨
I think it is a software frequency counter. Adjust the horizontal control. It needs to display a couple of full waveforms to be able to calculate the frequency. Most scopes are like this.

hi, how is it work with audio signal vs analog oscilloscope? how is the refresh rate of the screen vs 1104x-e ?
The cpu slows down trying to display audio (music tracks) my analog 20Mhz scope is smoother.. maybe I am doing something wrong?
@@Starcraftowns99 i have ancient ananlog since 1980s they are still smooth throughout time division scales. but i guess all digital oscilloscopes can not display smooth music signal slower than 1ms = 1khz. i did try to display subwoofer signal which are lower than 150hz, 5ms on time division of digital oscilloscopes is crappy.
your oscilloscope is the defective BA series.
i have this scope, I bought it for calibrating a few synths and have had no problems. However, I was designing a simple circuit with a UJT transistor (2n2646) as a simple oscillator and I wanted to see its resultant waveform. I was able to do that and all looked good, but the scope constantly goes into 'acquiring' mode and takes up to 30 seconds to refresh. It made using the scope really difficult as it couldn't keep up.
Has anyone got any ideas as to why this is happening or what I maybe doing wrong?
did you ever figure this out? I'm just looking at a dc signal, but anything greater than 50ms per division results in constant acquiring mode.
@@Pedro_Takahashi_Gunderson_Jr hi Pedro, yes kind of. The frequency was too low for the scope to capture. If you press the Roll button it will draw it in real time that helps somewhat. Also, using Auto my scope couldn't lock onto the waveform I was interested in, there was a lot of other DC noise in the signal, someone suggested reducing the bandwidth of the scope to effectively filter out the frequencies I wasn't interested in. Through a combination of these steps I was able to display the waveform I was looking for.... LFO's in guitar effects and synths are slow, when heard as audio you can hear them go up and down, so it kind of makes sense that you need a bigger capture time (time division) to display them, but then the scope can't keep up. I think that's the essence of issue in this situation, but I could be wrong, I'm learning still too.... I learnt the above from posting to a guitar effects builders forum.
@@silvertongues2 Thanks a lot for the response. I was trying to look at the charging and discharging of a capacitor and the roll mode allowed me to do that. I want to get into designing audio amps, analog synths and guitar effects. so far, I've read Make: Analog Synthesizers, which wasn't comprehensive enough for someone to get into detailed design, and I'm currently reading Designing Audio Amplifiers by Bob Cordell, which will take some time to get through. what approach have you taken to learning audio circuit design?
@@Pedro_Takahashi_Gunderson_Jr the same books, plus a few others. I've been building a lot of schematics and then using the books and forums to understand what is happening, and then I've progressed to making adjustments, and combining blocks of circuits to make my own design. And then I've tried to drill down into each block to understand how it works. I'm up to a point in which I know what parts are needed, and which components influence the outcome, but only high level understanding of what's happening at an electron level.... but, I guess the impression that the more you build (and debug) the better your understanding becomes.....I also found a few guys who I can call upon as mentors if I get stuck or have any questions. One of those guys is a trusted synth repair guy I've used, and the other is someone whose an active member from a facebook guitar pedal forum.... If you can find the right facebook group they're invaluable. Look up Guitar Pedal Builders group. People post schematics, and some really experienced guys offer help. (also, using LTSpice to review a circuit, rather than an oscilloscope, is quick and easy once you're learnt the software, it's what the pro's do when prototyping).
@@silvertongues2 thanks for all the info. I guess I'll just keep plugging away at it. spice programs are invaluable, but it seems tedious trying to input all the transistor characteristics. it's just another thing I need to do more of and I'm sure it will become easier. I'll look into the facebook group, it sounds very helpful. thanks again and good luck!
Vous avez appliqué la limitation de la bande passante en "Y" ou bien la sonde n'est pas bonne
Pavlin Nikolov Oui, j'ai eu la limite de bande passante. Je l'ai pincé dans un commentaire en haut de la page.
Are you thinking o selling your hantek?
Mike oliver no, it's my favorite
My current DSO is a 20 year old HP 54645A. It has a menu setting that allows a choice of Left, Center or Right for the Trigger zero reference position. Most of the time it is set to the Left because I'm only interested in seeing waveform after the trigger event. The Trigger zero reference position stays put regardless of change in Time base setting. I have been informed the SDS1202X E has the same ability. I have not been able to find confirmation in the operator's manual.
May an owner of the model please confirm?
Once one has become aware of this ability, DSOs that don't have it are unbearable to use.
=/ damn this doesnt do well with under 200hz? so if i feed it a lets say 40hz wave. it may not be able to track it properly??
+emerybryant It's ok, just not great.
learnelectronics for the price i was gonna pick one up. but i do a lot of audio. i frequently test using 40hz wave. so... thats a fail. lol what scope would be recommended?
+emerybryant I recommend this Hantek:
th-cam.com/video/JzfYSBwshyo/w-d-xo.html
It's available on Amazon for around $230
even the 200hz model is only about 330! lol so thats a good imo. i have an idea how to do the hacks to unlock the 200hz but ehh id rather just get the 200 model and call it a day but thanks. checking out the video now!
+emerybryant my friend, didn't you see what I said in the video? It comes pre-hacked from the factory. It's sold as 70MHz but you get 200!
