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.
