Topic: Controlling the AWG with SCPI command
Maybe someone could explain the intention of the SCPI commaArbnds with regards to the AWG. I tried a few. Most work as expected, like Basicwave (mostly, some glitches), Output, Storlist (huge list!).
What does not seem to work is ArBWaVe. What did I do:
1. Switch output on with: c1:outp on
result: Output is on, TE shows AWG menu
2. Switch basic waveform to Arb: c1:BSWV WVTP,ARB
result: Menu shows Wave Type Arb.., Arb type stair-up, And that is visible in the trace
3. Try to change the arbtype with: c1:ARWV NAME,PPULSE
A short glitch, then still stair-up.
Assuming, that the TE might have changed the Waveform for a short moment, I
a) selected manually Trapezia as the waveform
b) set the slope trigger such that is triggers on the trapezia waveform, but not on the ppulse waveform
c) set the waveform manually back to PPulse (no trigger)
d) send the SCPI command: c1:ARWV index,7
Result: Triggered with a surprising pattern. A mix of trying to switch to trapezia and then again falling
back to Ppulse. Screen shot below.
I could repeat that a few times. After a while, the TE did not respond any more at all to the
ARWV command.
Another strange effect:
Sending the command "C1:ARWV index,47" or "C1:ARWV index,25" breaks the SCPI interface. No command accepted any more, not even *idn?, until I disconnected and reconnected, or even had to reboot the TE. Sometimes it causes the TE GUI to completely freeze. No touch, no button press, no nothing, although the waveform update still worked. I had to power cycle the TE to revive it.
