I'm using an AD3 with the python SDK for this. Is there a way to define an RF pulse, and then play it out N times, but with a different phase each time? Rebuilding the pulse in a loop appears to be somewhat time consuming and would likely be imprecise. I can trigger the repeated pulses from a pattern generator, but I still don't know how to change the phase with each pulse. Of course, time is an issue, more than a few msec to update the pulse doesn't work.
A bit of code you helped me with some time ago is attached. Ideally I'd like the second pulse to be at a different phase. 180 is fine, but ideally any phase. The 180 I can do with some external hardware at the cost of 3dB insertion loss, but I'd prefer to do this in software.
Thanks for any suggestions/pointers! I have looked at the AnalogOut_Phase example, and tried to adapt it, but had no luck so far.
