Preparing for Initial Use of Your New FieldFox
Connector Care
Connector Care
— Never store connectors, airlines, or calibration standards loose in a box. This
is a common cause of connector damage.
— Install protective end caps when connectors are not in use.
— Keep connector temperature the same as the test instrument. Holding the
connector in your hand or cleaning connector with compressed air can
significantly change the temperature. Wait for connector temperature to
stabilize before using in calibration or measurements.
— Do not touch the mating plane surfaces. Natural skin oils and microscopic
particles of dirt are difficult to remove from these surfaces.
— Do not set connectors contact-end down on a hard surface. The plating and
mating plane surfaces can be damaged if the interface comes in contact
with any hard surface.
— Wear a grounded wrist strap and work on a grounded, conductive table
mat. This helps protect the analyzer and devices from electrostatic
discharge (ESD).
— Refer to “Connector Care Review” on page 715.
Because of the very small and precise mechanical tolerances of mmWave
connectors, minor defects, damage, and dirt can significantly degrade
repeatability and accuracy. In addition, a dirty or damaged connector can
destroy connectors that are mated to it. For this reason, NEVER use a
damaged connector. See also
