Use, Maintenance, and Care of the Devices
Gaging Connectors
Gaging Connectors
The gages available from Keysight 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.
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 then, 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. As the gages undergo more use,
the systematic errors can become more significant in the accuracy of the
measurement.
When to Gage Connectors
Gage a connector at the following times:
— Prior to using a device for the first time: record the pin depth measurement
so that it can be compared with future readings. This serves as a good
troubleshooting tool when you suspect damage may have occurred to the
device.
— If either visual inspection or electrical performance suggests that the
connector interface may be out of typical range (due to wear or damage, for
example).
— If a verification device is used by someone else or on another system or
piece of equipment.
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
and with previously recorded values
to evaluate the condition of device connectors.
