Inspect and Gage Connectors
1. Check for damage to the mating contacts of the test port center conductors
and loose connector bulkheads. If the center pin recession is incorrect,
replace the entire connector assembly (see Chapter 14, "Assembly
Replacement and Post-Repair Procedures. ")
2. 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 gauging and inspecting the device connectors.
If any calibration device is obviously damaged or out of mechanical
tolerance, replace the device.
Inspect the Error Terms
Error terms are a measure of a "system": a network analyzer, calibration kit,
and any cables used. As required, refer to Chapter 11, "Error Terms, ' for the
following:
The specific measurement calibration procedure used to generate the error
n
terms.
The routines required to extract error terms from the instrument.
n
Use 'lhble 9-l to cross-reference error term data to system faults.
