85071E software overwriting VNA settings

Question asked by askl21 on Jul 14, 2014
Hello,

I am trying to use the 85071E software with an E5071C network analyzer, for waveguide measurements at 1.7-2.6 GHz.  I calibrate the VNA manually, but when the 85071E software scans for new hardware or restarts, it changes the instrument state: resets the frequency band, turns off calibration, changes the calibration kit, changes the system impedance back to 50 Ohms from 1 Ohm, etc.  Is there anyway to prevent the software from doing this and simply just read in values when triggered by the user?  Thanks in advance.
