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