INTRODUCTION This appendix provides general, precautionary information and in-
structions pertaining to precision connectors.
C-2
PRECAUTIONS The following paragraphs are precautionary notes relating to mainte-
nance considerations for precision connectors
Pin Depth Problems 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).
