SCPI "TRACe:DATA?" command on SVA1015x
« on: October 26, 2022, 11:04:48 pm »
Is there a beginners guide to using this command?
With the SVA in SA mode, It seems to spit out 35 1/2 values, how do I know what frequency each one refers to? How do I get more than 35 values?

Thank you for any and all help!

This is probably a limitation of the UI rather than the unit directly - I've never used this SA but it certainly looks like the UI is just truncating the buffer - Install whatever the appropriate communication software is (NI VISA, Keysight IO Libraries, PyVISA etc) and then write a small program to send the command and read back the data - You'll probably end up with several hundred values that will be distributed from the start and stop frequencies of the sweep - For example, my HP 8563E returns 601 values so I would simply calculate the frequency based on start, stop, divided by 601.

Not sure if this helps very much but maybe it'll help you find the right answer.
