Mechanical Characteristics
Mechanical characteristics such as center conductor protrusion and pin depth are not
performance specifications. They are, however, important supplemental characteristics related
to electrical performance. Keysight Technologies verifies the mechanical characteristics of the
devices in this kit with special gaging processes and electrical testing. This ensures that the
device connectors do not exhibit any improper pin depth when the kit leaves the factory.
“Gaging Procedures” on page 3-10 explains how to use gages to determine if the kit devices
have maintained their mechanical integrity. (Refer to Table 2-2 on page 2-4 for typical and
observed pin depth limits.)
Pin Depth
Pin depth is the distance the center conductor mating plane differs from being flush with the
outer conductor mating plane. See
Figure 2-1 The pin depth of a connector can be in one of
two states: either protruding or recessed.
Protrusion is the condition in which the center conductor extends beyond the outer conductor
mating plane. This condition will indicate a positive value on the connector gage.
Recession is the condition in which the center conductor is set back from the outer conductor
mating plane. This condition will indicate a negative value on the connector gage.

The pin depth value of each calibration device in the kit is not specified, but is an important
mechanical parameter. The electrical performance of the device depends, to some extent, on
