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 center conductor protrusion or improper
pin depth when the kit leaves the factory.
“Gaging Connectors” on page 3-7 explains how to use gages to determine if
the kit devices have maintained their mechanical integrity. (Refer to Table 2-3
on page 2-3 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 when the center conductor extends beyond the
outer conductor mating plane, and will measure a positive value on the
connector gage. Recession is when the center conductor is set back from the
outer conductor mating plane and will measure negative.
The pin depth value of each calibration device in this kit is not specified, but is
an important mechanical parameter. The electrical performance of the device
depends, to some extent, on its pin depth. The electrical specifications for each
device in this kit take into account the effect of pin depth on the device’s
performance. Table 2-3 lists the typical pin depths and measurement
uncertainties, and provides observed pin depth limits for the devices in the kit.
If the pin depth of a device does not measure within the observed pin depth
limits, it may be an indication that the device fails to meet electrical
specifications. Refer to Figure 2-1 for a visual representation of proper pin
depth (slightly recessed).
