Inspect the Test Port Connectors and Calibration Devices
1. Check for damage to the mating contacts of the test port center conductors and loose
connector bulkheads.
2. Check the test set and power splitter connectors for defects as well.
3. Inspect the calibration kit devices for bent or broken center conductors and other
physical damage. Refer to the calibration kit operating and service manual for
information on gaging and inspecting the device connectors.
If any calibration device is obviously damaged or out of mechanical tolerance, replace
the device.
Switch Repeatability
Calibration does not compensate for the repeatability for the repeatability of the
mechanical transfer switch in S-parameter test sets, so the switch can be a source of error.
However, most switch failures are not subtle: no action.
Connect the test set to the analyzer. Press

switch.
• No sound: confirm that the test set has a solid-state (noiseless) switch, then refer to
"Test Set Troubleshooting" on page 9-8
• Audible sound: continue with this section unless a subtle failure is suspected. To
troubleshoot subtle failures, refer to the test set manual.
