When I was using PNA N5230A with 4 windows (S11,S12,S21,S22) I found that windows are changing position during the time of calibration.


For Example: in place of S11 window ,S22 is coming and in place of S21 window S12 is displaying.


But calibration and measurements are ok.


May I know how to rectify this issue.



Attached are the screenshots before and after the calibration with Ecal. Please see that windows are changing its position...Please help..
