and
and verify the following:
1.
Ensure that the Test Set is turned On and connected to the analyzer.
2.
Check all appropriate analyzer and Test Set connectors for damage, cleanliness,
and proper torque.
3.
Repeat the relevant 1-Port calibrations using another ECal or mechanical
standard.
4.
Verify that the analyzer is operating properly and meeting its published
specifications. If the analyzer is connected to the Test Set it will fail the
Operational Check. Refer to

ECal Confidence Check
The following procedure is a method to check the accuracy of a 1-Port calibration
performed with mechanical standards or an ECal module. In order 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 calibration on the Test Set port being tested.
2.
Connect the ECal Module to the port being tested. Terminate any remaining ports
on
the ECal Module.
