Hi
I am controlling SA44B and SA124B from SCPI. I would like to measure frequency error in zero span. I can get I nice zero span trace of my CW signal, but how do I get the signals frequency? When using the Spike app manually I can get a marker (By right clicking the plot) and make a peak search. How do I do this from SCPI? The normal maker commands do not give me a marker in Zero Span Spectrum PlotHi Torbin,
Zero-span mode has only partial support for SCPI. There is only commands for configuring the capture and then requesting the I/Q data. To achieve the functionality of a frequency marker, you would need to pull the I/Q data, FM demodulate it, then index your FM array accordingly.
This may be expanded in a future update, I cannot provide a timeline on when this would be available.
Let me know if you have follow up questions.
