- I had the opportunity to test the Rigol DS1104Z Plus and the Siglent SDS1104X-E oscilloscopes before to buy one of them.
Both 4 channel scopes are specified as 100MHz digital Oscilloscopes and in the price range of 500 €.
I hope you will find the video useful for your decision which one to buy. - วิทยาศาสตร์และเทคโนโลยี

Thank you for this comparison.
I just get a Rigol DS1102Z-E for €333 on Amazon. I hesitate between Rigol and Siglent for a 100MHz oscilloscope.
First the prices: $439 for Siglent DS1000Z-E, $333 for Rigol DS1102Z-E. For now, I am satisfied except for the following.
1) DC measuring (not AC) can be 20% false (even for the same signal on 2 different channels).
2) AUTO is slow (4 seconds).
3) A lot of trigger modes BUT no so called alternate mode (this allows to synchonize 2 frequency different signals on 2 channels).
4) A bit noisy.
5) Some select options are done by turning a knob and then to push on this knob but it frequently happends that pushing the knob turns it a little bit so you choose a bad option. Really unhandly.
6) Large screen but it's impossible to make a "full screen" of traces.
Now, for the good news:
11) Easy to use for and old electronician (>65:)
12) Quick answer from Rigol UK and Rigol China about technical questions.
13) Trigger functions work really fine.
14) FFT is usefull (for me).
15) Many storage options on internal memory or USB stick. Specially a one key present traces storage on USB stick.
16) Comes with full options enabled.
17) Help key than can be used at any time and shows the function of a pressed key (contextual result), very usefull.
One more thing to say: english, is not, by far, my natural language :O)
Thanks for your comment that you find the video useful for you decision.
Yes Auto on the Rigol is slower.
and One more thing to say: english, is not, by far, my natural language :O) -> same here ;-)
Enjoy your scope !
@@mse6424 Just for information: my comments, the same I write here have been prohibited on amazon although I thought they were useful and don't hurt anyonone :(
Thanks for testing and showing the difference with very low voltage signals👍
Excellent review. Thank you.
Excellent, thank you so much!
So, just to make sure, it's like this?
Rigol DS1104Z Plus
The frequency at -3dB signal level ---> 139 MHz
Max frequency that can be displayed ---> 400 MHz
Siglent SDS1104X-E
The frequency at -3dB signal level ---> 117 MHz
Max frequency that can be displayed ---> 250 MHz
Max frequency that can be displayed ---> 430 MHz
for the 100MHz - Version of the scopes you're right. I checked the unlocked Siglent again. The max frequency i can display on my one, is up to 600MHz (not with Auto-Function, you have to turn time and amplitude by yourself).
Up to 500MHz you can count the div's quite easily and estimate the frequency (max resolution is 1ns, full sine-wave on 2 divisions is 500MHz). At 550Mhz the diplayed wave becomes thick and unstable. The frequency is also diplayed numeric at the upper right corner, but here it counts only up to 399.999MHz
All measurements were made with a direct coax-cable connection, between generator and scope. Not with a probe!
best regards
I believe the steepness of the band pass filter on the analog side of the Siglent may be made on purpose to help avoid aliasing, being the sampling rate in interleaved mode only 500 Msa/s
Goob job!
Very nice, thanks mate.
You said below you used a 50 Ohm cable to measure the frequency response - have you used a 50 OHm termination at the scopes?
I could eventually make the same tests on a Keysight DSO1102 100 MHz unit.
Hi Rubens, yes i used a direct connection coaxial cable, teminate with 50 Ohms and no probes for this comparison.

THANK YOU!!!!
After watching several comparisons on youtube. This one sealed my choice.....
good to hear that. What is your choice?
Siglent !
cool !!!
Of course, some Silgent models are easily modified by removal of one cap per input channel, increasing BW to -3 at 345MHz. I would like to know if this is one that has that hackable front end. Some models use software controlled bandwidth, so no physical hack is available.
sorry i only saw a hack with removing caps on 2000-models. I guess that not possible on the 1000-series
I don't know about SDS110X-E, but each model in the SDS2000X+ series can have its bandwidth unlocked to 500 MHz without any physical modifications, only SCPI commands or input from keypad.
Hey there, hope all is well and appreciate your detailed reviews. Have a question for you when you have time..
I'm a retired electrical engineer and would like to buy a more modern 4 channel oscilloscope as more of a hobby item use than profession. In my later years the job I had did not require much use of one, so I'm a bit rusty, but presently I own an old 60mhz analog scope. In your experience - which of these two 4-channel models would you recommend? I'm torn between Siglent or Rigol currently, but open to suggestions. Just trying to get the most bang for the buck basically.
Siglent 1204-XE
Rigol DS1054Z
Thanks again for your advice!
Siglent is a little better brand and much more like the button layout on them as well. What many do, as well as I did, is that buy the 1104X-E for a much cheaper price and then with a software key (that you can not buy but exist on the internet) "hack" and change it to a 1204X-E and get 200MHz bandwidth.
What great Video and excellent comparison. Super Great! I hope you continue developing such videos. If you dont mind, I have a question, the point is that today, the Rigol DS1202Z-E (200MHz), has a great price in Amazon for about 356Euros, vs the Siglent SDS1202X(200MHz) about 400Euros. Now that you had the opportunity to work in both devices, which one do you prefer? and why? which model do you consider more ergonomic or easy to work? You were very clear from the beginning when you mentioned that the Siglent is more colorful and bright and the screen looks much better because of the size or the allocation of the space is better on the Siglent? Tell me?
Hi Erick, its not so easy to answer, because of your personal preferences. Because there are a lot of buttons right and left of the screen on the Rigol, the handling is better and faster to setup. The Siglent seems to have a better FrontEnd, the inputs are less noisy with 0,5mV/div. (Rigol has 1mV/div if i remember correctly). The power switch on the Siglent is a soft button, on the Rigol its a real switch. You can control the Siglent very easy via network, because it has a built in web-server. The Rigol need additional Software (maybe also hardware?). At the time i bought the scope, it was possible to update the scopes from 1102 (1104) to 1202 (1204) only via entering a key.
Same on the Rigol Models.
So i decided to keep the Siglent and sent back the Rigol.
I heard that the Siglent will be discontinued and that there will come new models, but i don't know if this is true. Same on Rigol????
Best regards Michael
@@mse6424 Hey Michael, were did you here the sds1000x-e series will be discontinued? I'm curious because I saw they just released a new model sds1104x-u which is a inferior model to 1104x-e.
@@andidotro i only assume that maybe siglent will also have new models in the near future, because the Rigol ones are very cheap right now
@@mse6424 One more question, after you hacked the siglent to 200mhz what is the maximum frequency on which it can go to? can it go closer to 400mhz like the rigol?
@@andidotro the timebase ends at 1ns / div. At 431MHz (from my handheld TX) my siglent shows a good sinewave, but i did not check the correct amplitude. i think it it will be a lot of -db :-)
Also the counter-display in the upper right corner of the screen, shows something wrong (like 350...MHz). So you have to count the divisions and calcute by yourself to get the correct frequency (thats doable!). As i do not have a Rigol here anymore, i can not compare.
Hello, I subscribed. I hava a question. Eventually, if you were to buy one of them out of your pocket, which one would you choose.
Hi Nathan, i had both scopes for compare and decided to buy the siglent for me. A very little more expensive, but it has a better front-end (the inputs are low noise) and i think the frequency range is a bit higher after modification
I'm surprised that the siglent doesn't have a proper power button and uses so much power in standby mode.
.... I turn mine off on a power board after it shuts down. (SDS2352X-E)
4W quiescent standby is unacceptable in contemporary consumer devices.
(We travelled to the moon on less than 4W).
@@robbieaussievic Yeah, we traveled to the moon with a thing made of sticks wrapped in tinfoil ;-)
Via remote you can easily change the bandwidth on the Siglent to 200MHz with an effective 3dB cutoff of 250MHz. This changes to the type to a 1204X-E.
yes i know! ... and also activate the options :-)
It won't increase refresh rate...
@reeder 76 Для идеального синуса.
Siglent $$ for upgrade, or a no-cost DIY method?
@@jenniferwhitewolf3784 no cost + know how to ...
I bought one and Im very dissapointed by Display quality. The display is too much bright/overbright and there is absolutely no brightness/backlit control (dim) on it! Black color look like grey. And white is extremely bright. Siglent logo and white colour FTT waveform absolutely burning my eyes. The Rigol DS1104Z which I have in work has much better diplay quality - more vivid colour and blac is black not grey. Im 34 yo so I have senstive eyes. I consider returning it because I cannot able to work with it more than 10 min.
I disagree RIGOL FANBOY!!!
Did you compare the noise of the fans? I bougth the DS1102ZE and very disappointed about the noise.
sorry i did not test the fans. but i think they are both nearly the same.
I replaced fan in my DS1054 with a silent one. Simple modification. I believe it was 50mm 12V Sunon original fan. I put another slowest Sunon fan I could find. No problems after 2 years
@@odissey2 Do have part # of the replacement?
@@gruneranfanger6947 This is all info I have from my other post on Rigol1054z. The fan appears to be about 15mm thick:
I replaced original 50mm 0.35W 12V Sunon fan with similar 0.18W fan. Additionally, I added 40oHm 1/4W resistors on each wire (total 80 oHm in series) to lower current. Now it absolutely silent. No issues with overheating.
I looked at DigiKey for closest match, 259-1815-ND: Sunon 50x50x15 12V 3200RPM 15.4dB(A) 7.7CFM airflow.
DigiKey listed 154 similar fans with 15.4db(A) from other manufacturers.
@@mse6424 from other reviews I believe that noise of Siglent's fan is comparable or even stronger than from Rígol.
How is the bandwidth split up over the channels?
bandwitdh does not split between channels, its the same on all of them. The sampling rate is split
If your frequency bandwidth measurements were done with the actual scope probes, then you are not taking into consideration the fact that the Rigol has a 150 MHz probe and the Siglent has a 100 MHz probe. The frequency response of the probe has a big impact on the measurement you showed here.
Hi Carlos, thank you for your comment. I'm aware of this and made the comparison with a piece of coaxial cable with BNC connectors. Wish you a good and healthy 2021.
@@mse6424 OK in that case you are correct . Not long ago I did the same thing checking one of my scopes that had a 350 MHz front end which seem to have a -3db point ~ 120 MHz I soon realized I was using a 100 MHz scope probe and when I went directly on a 1:1 via coax I definitely had the advertised bandwidth. A very Happy New Year to you as well.
02: What's a "com' par iz' on" ??
Hey msi,pls suggest an model between rigol ds1104z plus & sigilent sds1104 x-e
For newbie in laptop repair field
Or in some electronics gadgets power supplies?
Or simply i can buy rigol ds1054z
Bcoz some user comment here that they buy it with offically unlock.
Please explain some features details of unlock version of ds1054z like bandwidh limit,
Signal Measurement accuracy voltages measurement accuracy,memory depth etc.
I m using unit 2102cex right now.
Which one you suggest to buy for upgrade my work.
Thankyou....
i think the ds 1054 will do the job! it's upgradable via key up to 100MHz.
If you need a slightly better frontend to measure very small amplitudes and frequencies up to 200MHz, maybe the Siglent will be the better choice.
i did not do the unlock on a rigol, but i saw that there is a website with a key-generator, what makes it very easy to unlock.
Siglent is a bit more complicated to unlock.
I don't know if everything is still available and possible, but google will help you
both scopes can decode serial protocols etc.
@@mse6424 if i buy rigol ds1104z plus
Which you describe very well, will it come with officially unlock decoding or rigol give some trial period for use it?
I want to choose ds1104z plus over ds1054z bcoz i watch a video where shows rigol ds1054z auto function perform very low which i use mostly. What should to do confuse a little bit.if ds1104z plus comes with trial then definitely i will buy sigilent.
Pls suggest.....
@@samarsaifi8766 maybe it depends on the dealer, i'm not sure (ask your seller to make sure!).
My dealer promised that all options are included: SA-DS1000Z Serielle Dekoder, AT-DS1000Z Advanced Trigger, MEM-DS1000Z Memory Extension und REC-DS1000Z Recording-Modul! all for € 522,41 incl. 19% Tax
@@mse6424 thankyou m si...☺☺
I have 2 DS1054z scopes for general bench tech work for pro audio equipment and RF, plus 2 Tektronix analog scopes. I use the Rigol units most of the time but the Tek scopes are better for very low noise signal monitoring since most of these digital scopes are 8-bit data bandwidth.
tHE 1054Z IS REALLY full-featured for a low-cost scope. The additional features can be easily unlocked with has codes on other TH-cam channels that really increased the functionality, for free. The 3bd bandwidth is now 400mhz, and additional memory is unlocked plus many advanced trigger functions. The time base is surprisingly accurate compared to WWVL or my o oven stabilized 10Mhz frequency standard The voltage and time readouts are quite. accurate. I am very happy with these scopes. They have been rugged and never caused problems. One of them is used in a field kit and has been bounced around a lot, and dropped more than once yet still self-calibrates to tight specs and dos not even show scratches
The web server on the Siglent is not the right way to control a scope. The Rigol uses standard protocols which allow it to be integrated into a testing environment along with other GPIB-controlled gear.
The Siglent can be controlled over ethernet, using the SCPI commands given in the "Siglent SDS Remote Programming Manual" and considering the pricepoint thats quite impressive already.
Also I am not so sure if i'd want to use either of these scopes in a Test environment. I'd Probably prefer a techtronix or something comparable for that kind of purpose. Those scopes are probably better suited for enthusiats, students and such, not so much for professional use.
Why do all Oscilloscopes look like they are 20 years behind in technical development?
just wondering what should they look like as they are a tool that performs measurements. I was just looking a a Rohde & Schwarz 3000 series it has a single $2000 dollar fpga inside before any other components so the development is probably more on the inside than the out. saying that I have a Micsig tablet scope so perhaps things are changing.
I prefer knobs, not touch screen
The conclusion is siglent use cpu and looks like small computer. Rigol is just set of adcs and controllers... I choose siglent for upgradability.
The Silent has 2x500MHz ADC, while Rígol has true 1GHz ADC. The review doesn't show the shape of the short pulse, which will be in favor of Rígol.
I would stay with the brand name (Rígol, a spin of HP).
@@odissey2 CALM DOWN RIGOL FANBOY!!! SIGLENT HAS 14MPS PER CHANNEL AND 1GHZ ISOLATED WITH CHANNEL 3!!!
@@odissey2 you mean Sampling rate? the sampling is 2x1GSa/s not 2x500MSa so the siglent is actually better in that regard if you use 2 channels that would both sample at the full 1GSa/s vs the 500MSa/s on the rigol...
Please, what about DS1104Z AND SDS1204X-E??? Please tell me SIGLENT is better!
people hack the 1054Z to 100MHz and hack the 1104X-E to 200MHz why not between those? The siglent is better but pricier
@@rokiedecentra9656 They spend more time hacking than just buying the siglent 1204.
