1. Ensure that the test set is on and connected properly to the analyzer.
2. Check all appropriate connectors for damage, cleanliness, and proper torques.
3. Repeat the relevant 1-Port calibrations using another ECal or mechanical
4. Verify that the PNA is operating properly and meeting its published specifications.

ECal Confidence Check

The following ECal Confidence Check is a method to verify the accuracy of a 1-Port
calibration performed with mechanical standards or an ECal module. To perform this
check, the test port of the ECal module must connect directly to the Test Port being
verified (without adapters).
1. Perform a 1-Port Cal of the test set port being tested.
2. Connect the ECal Module to the Port being tested. Terminate any remaining ports
3. Select the Cal Set to be verified. Select
