New Hantek DSO2X1X models?
<< < (362/388) > >>
phmarek:
I have no idea -- DavidAlfa suggested it!

And it's not that no key worked -- a few of them did, once or twice.


My hunch would have been to look at the FPGA firmware, as that one's responsible for translating key presses to input events.
Aldo22:
When I tested the script (above), I found that the frequency response with the tinysa from 1M to 150M was not very flat or linear. (-> picture, direct connection, dummy load, no DUT).
10dB gain over the frequency range.

Now I'm wondering if it's the Hantek, the tinysa, the cable or the script.
Unfortunately, I think the Hantek is the culprit, but I would prefer it to be for other reasons.
Does anyone know anything about it?

Can someone check this with a decent signal generator?
It doesn't have to be with the script, a few measurements would be enough (e.g. 1, 10, 50, 100, 150 MHz).
Perhaps someone has already tested this?

Thank you.
Aldo22:
If I connect the oscilloscope to the PC via USB (SCPI), does it make sense to use an Adum3160 USB Isolator ?
Do the SCPI commands work with it?

E.g. https://www.eevblog.com/forum/reviews/chinese-usb-isolator-test/

Thank you!
