INSPECT THE CONNECTORS
Check the physical condition of the analyzer front-panel connectors, the calibration kit devices,
and the test set connectors.
1. Inspect the front panel connectors on the analyzer. Check for bent or broken center pins
and loose connector bulkheads.
Gage the connectors. (Gage kit is HP part number 85054-80011.) The specied front-panel
type-N connector center pin protrusion is 0.201 to 0.207 inch.
If the center pin protrusion is incorrect, replace the entire connector assembly or A9 input
multiplexer. See the Replaceable Parts chapter.
2. Inspect the calibration kit devices for bent or broken center conductors and other physical
damage. Gage each device. The mechanical specications for each device are given in the
calibration kit manual.
If any calibration device is out of mechanical tolerance, replace the device.
3. Inspect and the gage test set and the power splitter connectors as described in steps 1 and 2.
