My method of communicating with the analyzer is via SCPI commands issued through the telnet server on the analyzer. In the past my general method for taking a measurement at a certain frequency has been to set a marker at that frequency for the channel/trace and then read the Y value. In my current situation I would like to take measurements for 512 distinct frequencies across a single sweep. Given a 9 marker limit I can't accomplish this the way I have in the past. Is there an alternative way to programmatically obtain measurements for a sweep of all 512 frequencies at once?
