Hi all, I have an old Agilent 4194A gain-phase analyzer and want to query the instrument via GPIB to get data. Unfortunately, the user manual is not very helpful. It lists a query "A?" to get the complete measurement curve, however, I would like to only get one pair of x-data (frequency) and y-data (amplitude) after setting the marker to the max value. "MKRA?" seems to do the trick for the amplitude, but I do not find a query to get the x-position of the cursor. Anybody having a suggestion? I have already contacted Agilent, but since the tool is old, they could not help. Best regards, alex Legal Disclaimer: The information contained in this message may be privileged and confidential.
