I'm using a 81180A AWG to create arbitrary I and Q at 1 GHz. These are input to the wideband I and Q inputs on the E8267D. I see no way to trigger the modulation on the 8267, so the LO and modulation is on, then I trigger the 81180 to send the ~ 2 microsecond waveform. My problem is, shot to shot the phase between the 1 GHz waveform and 7 GHz carrier vary by Pi/4. Is there some way to sync the 81180 and the 8267 so that the modulation always starts at the same point on the carrier wave?
Thanks in advance.
Thanks in advance.
I have engaged several different colleagues here, but we do not understand what you really want to achieve.
We need more information. Can you provide us with a ‘timing diagram’ of the desired outcome - and the PRI?
Hope we can help -
