This appendix provides general, precautionary information and in- structions pertaining to precision connectors.

The following paragraphs are precautionary notes relating to mainte- nance considerations for precision connectors

Based on ANRITSU precision components returned for repair, destruc- tive pin depth of mating connectors is the major cause of failure in the field. When a precision component is mated with a connector having a destructive pin depth, damage will likely occur to the precision compo- nent’s connector. A connector is considered to have destructive pin depth when the center pin is too long in respect to the connector’s ref- erence plane (Figure C-1).

Before mating an unknown or new device with your 373XXA Port con- nectors or calibration devices, always measure the pin depth of the de- vice’s connectors. Use a ANRITSU Pin Depth Gauge, or equivalent, for these measurements (Figure C-2). Also, measure the connector pin- depth of a device when intermittent or degraded performance is sus- pected.

Gauging sets for measuring the pin-depth of precision connectors are available from your nearest ANRITSU Service center, or from the fac- tory. Instructions for measuring connector pin-depth are included with the gauging set(s).
