Thanks, manual was kinda crappy but your video helped great deal I couldn't even change the scales until I watched this video so thanks again.

32:40 Not to the 10 Volts but to the 10Mhz!!!!

Version V0.0.5:
The following changes have been made since version V0.0.4:
1. Fixed a bug where the oscilloscope's measurement level was halved when the frequency was below 980Hz.
2. Fixed a bug where the waveform display was incorrect when the oscilloscope was paused.

Version V0.0.4:
The following changes have been made since version V0.0.3:
1. Fixed a problem where the signal generator switch would fail.
2. Modified the display of the scrolling time base.

meander test at different frequencies and not just sine

I see you have the DS215H attached to a stand. What stand is that? Link?

Could you add a section to your videos on what is really new with respect to other models of the same supplier?

una pena que no acepte sonda X100, seria perfecto!

@Peter-rt3tu 11 months ago

In the bandwidth test, you test some 50MHz signals in a milliseconds range? That can only be some aliases, right?

@samsonveriz 7 months ago

wtk where is meander??

@benthillerup 9 months ago

How is this comparing to the 2C53P (scope part) ?

@DissidentPenguin 11 months ago (edited)

Great review. Thanks a lot! One question. Is there a way to calibrate the probes with this oscilloscope? Also for the bandwidth test, how would it differ if you used the
cables that come with the oscilloscope instead of the 50 Ohms terminated ones?

@OMNI_INFINITY 11 months ago

So the FFT is merely a gimmick FFT without any windowing options and so on?

@ГригорийКарелов 1 year ago (edited)

Hi.
1.
10:10 The sensitivity of the first channel is 1V, the second is 100mV. Are they the same on the generator and on the oscilloscope? Where's the error?
2.
31:29 Up-p readings are not correct if the oscillogram goes beyond the screen.
3.
31:10 Why, with different frequencies on the channels, the lower is 10 MHz channel practically synchronized with the upper 25 MHz?
4.
Why turn on automatic mode every time you change the generator frequency? It's better and more intuitive to manually change the sweep mode on the oscilloscope; this will eliminate possible software changes to the signal amplitude measurement.
5.
29:49 The entire band of the device is 50 MHz, but the generator now only has 25 MHz. :)
6.
You have a good generator, why don't you show how the device displays a square wave at the maximum frequency available to it?

There are no values from 1s up to infinity on afterglow???? How lame is this? Why implementing features, when you could barely use them at all?

I had ordered it already when I found this video, but just wanted to let you know that at least from Germany both affiliate links seem to be dead. So far I'm loving it, but just wish the FFT was a bit more like that of the Zeeweii DSO3D12. I can't imagine what usecase can be solved with the FFT in the DS215H. Does anybody have an idea?
