Links to the best digital oscilloscope we listed in this video: 1. Zeeweii dso3d12- s.click.aliexpress.com/e/_DdDwEW9 2. Zoyi zt703s- s.click.aliexpress.com/e/_DFTwnrL 3. Bside zt702s- s.click.aliexpress.com/e/_DChg2gp 4. Gvda Gd188- s.click.aliexpress.com/e/_DClXoyD 5. Fnirsi dso152- s.click.aliexpress.com/e/_DebuVB3

Fnirsi link is incorrect

The only somewhat usable among them are the ZOYI/ZOTEK ZT-702/703 units. The rest are just colorful toys.

They are all literally the same thing just a different name and maybe different button layout

[@michaelroberts1120]

I beg to differ. In other videos, there were a number of bugs uncovered with the ZOYI devices, including aliasing. In my own experience and after seeing many other videos, it seems that the best and most solid offering is the Zeeweii. For only $80 US you get a 120 MHZ single channel bandwidth (this has been tested and verified), a basic but usable FFT (no window or binning options; seems to use flat top - no window function - but nevertheless, one can see and measure the frequency of waveform harmonics, even though amplitude measurements are not supported. There is also an "easter egg" that is not mentioned in the user manual - a six digit frequency and event counter, which you find by pressing the "display" button in the menu twice. That feature alone makes this device a far better value for the money than all the others.

@@michaelroberts1120 What function activate shift+V(ch2) ?

[@michaelroberts1120]

@@ErvoSilva I think that activates voice command, but I've tested this feature and it works so poorly that I can't see it as more than a gimmick. It is amusing though because the voice does sound like Tricia Takanawa from Family guy.

How about fnirsi dpox180h?

I have a FNIRSI DSO 152, but now I'm disappointed because it doesn't work properly and I can't measure anything or set the amplifier in the car. The maximum measured electrical voltage from the Head unit RCA pre out output shows me ONLY 0.43 Volts at the maximum set volume and this without any distortion of the clip signal. I think there is something wrong with this oscilloscope because it was working normally from the very beginning but now it is NOT. I went to measure the old battery from the vehicle and it correctly showed 12.52 volts and let's say the voltmeter showed 12.46 volts. Again, he disastrously showed the electrical voltage in the apartment, where he measured ONLY 147 volts, but the voltmeter measured 239 volts, which is correct, and now I'm skeptical because the oscilloscope is not right. Again, I will have to get an oscilloscope or a multimeter with an oscilloscope, so that I can measure and adjust the sound system in the vehicle.

Can it be linked BY pc or lcd

Лак какой лучший? Из этих ☝️

[@berrywin]

A bandwidth of only 200 KHz is not usable for much! My 40 year old cheap oscilloscope has 10 MHz of bandwidth!

[@tomorrowsnews3915]

eBay is the way?

[@vincentpritchett1231]

If you’re just using it for audio troubleshooting(and that’s the main use for any of these), any of these are adequate for that.
