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.
