Hantek HDG2002B AWG: 5Mhz or 100MHz? Let's see!
<< < (121/134) > >>

Yes Berni,

i do know, but at least AM modulation was working before last FW update.
markone:
Well,

just tried to revert FW to 1.00.3 (141225.0), now AM mod works good, see attachment.

Broken modulation apart, with ver. 150807 the user interface was a lot more sluggish than usual, maybe the last firmware is only for PCB "1004.1", mine is "1004".

Now i'm wondering if i am the only one with this problem ....

alex.forencich worked on the FPGA software and I am currently working on a GUI version.
I don't have other AWG to compare with.

Any news on this?

With what settings did you get waveform like that?

I really tried different settings but the AM seems to be working on my unit. Only thing I noticed that if I set some divisible ratio between modulation and carrier (for example 1:10) so that I can see the modulation changes and carrier cycles in same time, the carrier phase is constantly "rolling" against modulation phase - what it should not do if the ratio is exactly divisible. So it's possible that the modulation frequency has very little error against carrier frequency or vice versa.

I also noticed that there's MUCH more waveforms in the arbitrary menu now and the frequency of arbitrary waveforms are now correct. With previous software, if I set CH1 to sine for some frequency and then select exact same frequency for CH2 and select any of the arbitrary waveforms, the arb. frequency had little error.

Now they are exactly synced.

But I can verify what's said already earlier: frequncy counter function is now dead. No readings with any kind of signal anymore.

Similar behaviour with any kind of setting, anyway this problem disappeared reverting to older FW revision.

Your PCB is 1004.1, mine is 1004, also FPGA code is different (4.1 vs 2.1), i fear that the last FW file shared on this 3ad is only for your HW revision.

One positive thing is that now FM modulation is working properly, previously was not, probably due to FPGA code update 2.0->2.1 (SW downgrade left it to the latter).

I'm wondering if exist a web channel to ask  Hantek proper firmware release for the specific owned HW revision, if anyone succeded in that please share the way.
