Calibrating the Test System

Figure 6-1 Calibrating the Test System

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.
