Hi gga33,
Thanks for contacting us. I can help you with your questions.
a. In our software switching between sweeps and QP detector is manually done with the Start/Stop buttons in the control panel under the “Meter Settings” tab. Additionally in the Peak Table control panel along the bottom of the screen, you can select a peak and move the settings to the QP detector by pressing “Selected Spur to Meter”. In the meter settings you can control the dwell time parameter.
b. The only way to change the measurement points in the sweep is to change the RBW. You currently cannot directly set the number of points in the sweep.
c. You will need to use the “Scalar Network Analysis” measurement mode in Spike for return loss measurements. There is a step-by-step setup guide in the manual (you can bring the manual up in the help menu). You can also watch the Justin setup up the software for SNA measurements in this video https://www.youtube.com/watch?v=hxUZx-9DMYg
Let me know if you have follow up questions.
Regards,
Andrew
