I need to measure TDM timing relative to PPS. Is there a way to either trigger zero-span sweeps with PPS from the internal GPS receiver or display the PPS state on the Spectrogram? I’m currently using an external PPS source as a trigger. This works well enough for my current need, but would be nice to specify internal PPS as a trigger source and possibly display PPS state on time domain displays.
If using Spike there is unfortunately not a way to trigger off the internal PPS.
If using the API, then this would be possible by using the I/Q timestamps. When I/Q streaming via the API with GPS lock, the timestamps would give you indication of when the PPS trigger occurred and you take action at the appropriate time.
