Hello,
I want to record IQ data signal. I have a trigr set on the rising edge, but it seems that the trigr is working on the leading edge (see Picture). If I then try to play recorded data, I can only see part of the signal. It was as if only the descending edge was responding to the recording. The displayed record can not be moved to the left, up to half of the record. Trigger position it also affects the recording of IQ data, or only the display of data.Hi hhonza,
Try disabling the video trigger when you are playing back the capture. This will allow you to scroll through the data. When you are playing the signal back and the video trigger is active, it attempts to find triggers in the capture and overrides your manual scrolling.
Once you are able to scroll through the data, try zooming in on the falling edge of that pulse to verify it is a smooth descent.
The trigger position control only affects the display of the IQ data. The pre-trigger setting on the IQ recording toolbar affects how much data before the trigger gets saved.
Let me know if you have additional questions.
Regards,
Andrew
