Calibration and Test

For the best accuracy, you should perform a full two-port calibration between ports 1 and 3 on the test set, and again between ports 1 and 5. As mentioned before, you need to save the calibrations as instrument states. For information on how to calibrate and store instrument states, refer to the PNA Series Network Analyzers User Guide, part number E8356-90001.

CAUTION

Do not use the test set to change the RF signal path direction when you

 

are using a full two-port calibration. Doing so will render the

 

calibration invalid. Instead, use the internal transfer switch in the

 

analyzer.
