Specifications
Mechanical Characteristics
NOTE
The gages for measuring type-N connectors compensate for the designed
offset of 5.26 mm (0.207 inch), therefore, protrusion and recession readings
are in relation to a
zero reference plane (as if the inner and outer conductor
planes were intended to be flush). Gage readings can be directly compared
with the
observed values listed in Table 2-2 .
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 2-2 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 an illustration of pin depth in type-N connectors.
NOTE When measuring pin depth, the measured value (resultant average of three
or more measurements) is
not the true value. Always compare the measured
value with the observed pin depth limits in Table 2-2 to evaluate the
condition of device connectors.
