Temperature—What to Watch Out For
Changes in temperature can affect electrical characteristics. Therefore, the operating
temperature is a critical factor in performance. During a measurement calibration, the
temperature of the calibration devices must be stable and within the range shown in
Table 2-1.
IMPORTANT Avoid unnecessary handling of the devices during calibration because your
fingers are a heat source.

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. Agilent Technologi es verifies the mechanical
characteristics of the devices in the kit with special gaging processes and electrica l 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 3-6 explains how to use gages to determine if the kit devices
have maintained thei r m ec hanic al i nteg ri ty. Refer to Table 2-2 for typical and ob s erved 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 conditio n will indicate a posi tiv e v al ue 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.

Mechanical Characteristics
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 its pin depth. The electrical specifications for each device in the kit take
into account the effect of pin depth on the device’s performance. Table 2-2 lists the typical
pin depths and measurement uncerta inties, and provi des obser ve d pi n dep th l im its f or 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).
