Hi Justin,
Thanks for the reply.
I tried the zero span with video triggering. It worked very well.
But it seems to have no peak mark tracking capability that realtime mode has.
I also tried realtime mode. It worked as well.
The peak frequencies captured by in these two modes really have good consistency.
Now I’m trying to readout the peak frequency through SCPI command. I read the manual which says the zero span mode is not supported by SCPI yet. So it seems I have to rely on the realtime mode.
As such, could you let me know what SCPI command I should use to get the peak mark frequency read from Spike?
Thank you very much.
