hilarious - I have been looking at all these testers the past few days. Thank you for doing these videos, the reviews are very informative. I appreciate that you are to the point with these testers, no beating around the bush. Pure experience to honesty to the functions it says it should provide.
I'm astounded at the value! that much performance for $25 is really good. Even with a 200kHz analogue bandwidth (which I'm sure is limited by an input filter that could be 'adjusted'😂, it's really great for situations you mention. Heck, you could even use it to explain aliasing and digital down-conversion with a 455KHz IF AM radio. How to use a scope and how to interpret the waveform is 80% of mastery. I'd pay an extra $5 for a trigger input that doubled as a 1-ch logic analyzer. Really cool!
Bandwidth is likely limited by the internal A/D sample rate, so while you might be able to "adjust" the input filter, you would not gain much in terms of performance.
At 8:00, the vertical ranges will probably depend on the probe attenuation. At 9:40, triggering wasn't a problem -- the pulse train was stationary; the problem was the sampling frequency beating with the pulse frequency... instead of sampling at the peak it sampled half-way down on each side during some traces.
@@_N4VE_ at first i couldn't get it to read either but eventually i got it to work and it does the job. Don't use auto, try manually using different settings until you get it to read.
Might be useful for checking Hall effect sensors on my car. Wouldn’t want to drag my expensive oscilloscope out to the garage and risk getting it all dirty or broken.
You definitely don't want your scope turning into one of those "pulled from working environment" eBay units where the "working environment" seems to be under the hooves of many cows in a barn.
I did a review of this a month ago in my channel and I really liked it, it is fast for the price! For audio usage and mains measure (using the 10x probe obviously) is quite neat!
For 25USD its a great tool. U can check switching power suply, U can check comunication between PCH and BiOS chip, U can check linaerity of Ur suply, U can do many things. Especialy U can teach how to measure with osciloscope AND it is on battery, so U are out of grounding👌🏻
I CANT BELIEVE ITS 25 BUKS ! waw that blows my mind, this unit is great for on the car use or under bonnet stuff wear you get it covered in oil and soot so many uses such amazing value when i was a young dude i would fantasize about oscilloscopes and could not get one ...
This seems like fine companion to Hantek 1008 I have used for years to work on cars. Single channel and sampling rate are limiting capabilities but it being small stand alone device is great to get a quick read from some sensor when you dont want to set up the Hantek.
I don't know how this Fnirsi is powered but I blew up a similar inexpensive one when I decided to power it externally with what I thought was an isolated PSU. I can't remember what I was doing exactly but i tried to measure something with respect to mains only to find out the negative rail of the PSU output was actually earthed! I had assumed, because the PSU was just a big black plastic block, it was double insulated. Sadly for my cute little scope it was not 😢
Human hearing frequency range is 20 to 20,000 Hz - so am I correct in assuming this device would be sufficient for seeing audio frequencies on a guitar pedal? Thanks!
I must have gotten the next generation of this $20 scope on 07/25/2024 from Banggood. It has two inputs at the top, DSO and DDS, and it displays the stats at the bottom of the screen. Happy with it.
At 9:20, it appears the problem with the sync pulse triggering is not the scope: it's either that the amplitude of the pulse varies, or (at 200mV / div) you're getting quantization error on the signal. That would make it appear to shift slightly. There also appears to be a little noise in the signal which could make it appear to shift.
I did. And the drool immediately evaporated when landing on the tops of the vacuum tubes of my first 70s scope. This tiny thing would have been Unobtanium.
Wonderful video! All of your videos are great, and yours might be the only YT channel that I can say that about.. This fulfills another wish I had, besides low cost. I am excited for more scopes, or other instruments, that don't need to connect to mains.
Im learning electronics, im far from rich, but most electronic componants are within my price range, so a 20 quid Oscilloscope is a dream for me, ok its limited but 20 quid or 2+ grand, a no brainer for me. Thank you for the review, it helps me a lot.
Ty for the unbias review! I bought for exactly the reason of room/shop swapping. Ill program in my comfy room, when i need to quickly check low freq comms, or even just snap shot a voltage reading and a curve. ill use this. Would hate to drag out the riglol on a field mission to just to confirm its dacing and not dead. Haha
I became interested in electronics as a kid back in the late 50s and I would have given a few limbs to have anything 1% as good as this. There is no doubt a scope is the single most useful tool in grasping an understanding of electronics - especially analogue electronics.
Actually, it did say it was calibrating on screen but it was brief. Watch your video. I just got mine today and it looks great. I wish you would have gone to a little more detail. I cant get to connect to my PC (W10 sees it but says it is malfunctioning). The instructions are not at all clear to me. And I would like to update the firmware. Some other youtuber fixed an old Commador 64 with 4 problems using this. And I would like to see if this DSO152 would project to the PC screen. Thanks for the review.
9:02 When you started talking about a "sync pulse" before zooming in, and I just saw the spikes, I assumed for a moment you were talking about some synchronization pulse. Then you zoomed in and I recognized the function as a "sinus cardinalis" sinc(x)=sin(πx)/πx, and I understood you were talking about a "sinc pulse" rather than a "sync pulse". BTW, according to the cc subtitles you talk about a "sink pulse", which briefly added to the confusion.
I bought this to simply test the sine/modified waves for inverters as some of the more expensive ones are listed as sine when in fact they're not. Still trying to figure it out though.
im looking to get one of these for simple electronics repair/diagnosis stuff, mostly testing for switch mode power supply clocks, Do you think this would be sufficient for such?
So what is the crosshair “trigger” you referenced on the sides ? I thought it was going to let me shift the wave along the “Y” axis but it does not ? Basically I’m trying to use this for checking a 40hz sine wave for setting my amplifier gain but I’m not able to keep the image within the confines of the screen? I’ve tried to slow it down and get it the smallest but it’s not helping🤔
Is there a mode to capture a single event? Like if i pull my outboard motor and record the crank sensor. Can I check the pulses after the pull in a "recorded" state?
Bought this to test inverters. Can not figure it out. Do not know what settings to use or where you put the probe and other black wire to test an AC socket. I guess you have to already know how to use these when you buy it. Instructions are no help and what videos I have found so far only show the screen and the wires are aways going off screen so I can't see the connections.
Can you use any bnc scope leads? I have a pico lead but not sure if it would fit? I want to use it for automotive sensors and can bus etc but not crazy on the short lead’s like in the video
1Mhz would be nice, so you can look at boost / buck switchers. I would spend a bit more money for something you knew could do that. Yes it's a slippery slope of how fast to go, but eh these bare-CPU-ADC oscilloscopes are getting a bit old hat, and the interfaces are all sad to work with
Do you know which processor it's using? Could make a great dev machine if it's hackable. Nice ergonomics. You'd pay more than that for a decent production quality project case. Edit: Found it. CH32F103. It looks like there's a UART header too so the STM32-Arduino framework might be worth experimenting with.
@@nikthefix8918 AliExpress some European put review photos with opened view. from there i understand FPGA chip company started 2014 have their chip used.
For the price - it's amazing. As usual, it's the 'right tool for the right job'. You're certainly not checking the clock on a 5ghz clock signal with it. Wrong tool. It's WAY cheaper than the first 'cheap' DMM I bought in about 1979. Factor in inflation?! OMG.... SO much cheaper. Still have that meter BTW!
Hi , I am knew to electronics. I replaced an alcohol addiction with electronics. At first I didn’t know how to use a breadboard, now I have built a MOT self starting Jacobs ladder and some Slayer Exciter Circuits. I just ordered a mini oscilloscope and it should get in in a week or so. I want to build a pulse laser driver to run a 905nm 75w laser diode that has a typical voltage of 12.8v 30a 100ns max pulse 0.1% Any idea’s of a simple cheap way to drive the laser diode ? The arduino is too slow, so I found I can generate a 100ns PWM with a 555 timer but I don’t know what MOSFET to use for the 100ns switch and if I need a capacitor or what size and if I need an inductor ? Any thoughts ?

I think this might be an ideal tool for setting gains on audio amplifiers. Cheap and cheerful. Useful video, thank you.

I'm an auto tech and having a really cheap one channel battery scope is very useful.
You definitely don't want your scope turning into one of those "pulled from working environment" eBay units where the "working environment" seems to be under the hooves of many cows in a barn.
Exactly what I was going use one for! See if your cam sensor is pulsing (or whatever), and it's plenty fast enough to check if the CAN bus is alive.
This one won't even get dirty, 'cause it fits right in your front pockets!
Would this too work to check pickup coil AC voltage on a motorbike?
Great ringtone. Oh, and the scope is a nice upgrade from a DS0138.

Could be useful cause it’s not connected to mains ground. Being new to oscilloscopes and not having to worry about shorting out parts might be good.
