PRECAUTIONS The following are precautionary notes related to the use of connectors.
For specific information on setting pin depths on sliding terminations,
refer to the 37XXXC Operation Manual, Chapter 7.
Pin Depth Before mating, measure the pin depth (Figure 13-6) of the device that
will mate with the RF component, using a
ANRITSU Pin Depth Gauge
or equivalent (Figure 13-7). Based on RF components returned for re-
pair, destructive pin depth of mating connectors is the major cause of
failure in the field. When an RF component is mated with a connector
having a destructive pin depth, damage will likely occur to the RF
component connector. (A destructive pin depth has a center pin that is
too long in respect to the connector’s reference plane.)
Pin Depth Tolerance
The center pin of RF component connectors has a precision tolerance
measured in mils (1/1000 inch). Connectors on test devices that mate
with RF components may not be precision types and may not have the
proper depth. They must be measured before mating to ensure suit-
ability. When gauging pin depth, if the test device connector measures
out of tolerance (Table 13-1) in the “+” region of the gauge (Figure
13-7), the center pin is too long. Mating under this condition will likely
damage the termination connector. On the other hand, if the test de-
vice connector measures out of tolerance in the “–” region, the center
pin is too short. While this will not cause any damage, it will result in
a poor connection and a consequent degradation in performance.
