Use, Maintenance, and Care of the Devices
Gaging Connectors
Gaging Connectors
The gages available from Agilent Technologies are intended for preventive maintenance
and troubleshooting purposes only. They are effective in detecting excessive center
conductor protrusion or recession, and conductor damage on DUTs, test accessories, and
the calibration kit devices.
Do not use the gages for precise pin depth measurements. See
Connector Gage Accuracy
The connector gages are only capable of performing coarse measurements. They do not
provide the degree of accuracy necessary to precisely measure the pin depth of the kit
devices. This is partially due to the repeatability uncertainties that are associated with the
measurement. Only the factory—through special gaging processes and electrical testing—
can accurately verify the mechanical characteristics of the devices.
With proper technique, the gages are useful in detecting gross pin depth errors on device
connectors. To achieve maximum accuracy, random errors must be reduced by taking the
average of at least three measurements having different gage orientations on the
connector. Even the resultant average can be in error by as much as
±
0.0001 inch due to
systematic (biasing) errors usually resulting from worn gages and gage masters. The
information in
assumes new gages and gage masters. Therefore,
these systematic errors were not included in the uncertainty analysis. As the gages
undergo more use, the systematic errors can become more significant in the accuracy of the
measurement.
The measurement uncertainties in
are primarily a function of the assembly
materials and design, and the unique interaction each device type has with the gage.
Therefore, these uncertainties can vary among the different devices. For example, note the
difference between the uncertainties of the opens and shorts.
The observed pin depth limits in
add these uncertainties to the typical factory
pin depth values to provide practical limits that can be referenced when using the gages.
See
. Refer to
the design of the calibration devices in the kit.
NOTE
When measuring pin depth, the measured value (resultant average of three
or more measurements) contains measurement uncertainty and is not
necessarily the true value. Always compare the measured value with the
observed pin depth limits (which account for measurement uncertainties) in
to evaluate the condition of device connectors.
