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

<< < (42/134) > >>

Well a couple of things:

- I tried loading both the sine and square files; the sine had nothing it in, and the square one had a 1KHz square wave in it. I could not upload either to the HDG (not sure why that isn't working, but it is probably a case of I'm not using it correctly).
- Against my HP 5334, I measured the sine wave output, 10MHz, at 9.999681 MHz (pretty close).

Again, it isn't the frequency that seems to be off, but the phase of the output that is wandering.

Thanks for that, the alternative nanddump seems to work. The files are available here:

By the way, I didn't remove my serial from the system.inf, it was set to 'undefined' from the factory.

I would expect to see both the ref and output signals sync'ed.

This is the best I could do.  I manually dialed in the sine wave frequency (top) to stabilize it relative to the 10MHz out signal (bottom).  The jitter is really bad.  Maybe I'm doing something wrong setting up the measurement.

@FrankenPC: Thanks for the measurements!

Both are related. With the arb function and TTsource I am pretty sure you would have less phase problems and a more accurate frequency.
The files I posted seem OK  :-//
