Hantek HDG2002B AWG: 5Mhz or 100MHz? Let's see!

@ andrija :

have you tried to use & verify FM modulation on sine signals ?

With my "Toy" i obtain one of the following results :

- no modulation at all
- wrong modulation
- BSOD, followed by reset loop followed by Recovery Request

I would also ask if your instrument keeps the very screen intensity parameter that you set under system setting menu.

Mine changes it on quitting the menu, re-booting the device and so on.
 

andrija:
I just played with it for a bit. External modulation does not work, either FM or AM (I used the second channel and connected it to MOD jack). Internal modulation kind of works, but almost every time I get a different behaviour for the same setting. Sometimes it does not work at all, sometimes I get one kind of waveform and sometimes another. My Rigol 2072A also likes to lock up often when viewing it. Anyhow it seems it behaves similar to yours except I didn't get any BSOD at all, just basically a random result every time you're in that menu (and it changes when you reboot, too). Like a said, a toy.

Many thanks andrija,

at least now i know it's not my peculiar instrument fault.

So, as i already said, this instrument is currently sold even if the firmware is still in beta stage (at best).

Not fair at all.

PS : BSOD with FM mod occurs with particular parameters combination

Just to finalize my lame, in attachment some sync output glitch screenshots, present when sine signal freq is below 500Khz  :palm:

andrija:
I don't seem to be able to reproduce that, but my sync signal is very jittery above 1MHz, as is the actual signal above 10 or so. I managed to lock up Rigol's front panel doing that, too. Screen was updating but no buttons were working at all, except power button.
