Recession Limits
The female receptacle recession and the male pin
recession, along with other mechanical specifications of
Port 1 and Port 2, must be within limits to meet complete
measurement specifications. The precision adapters
supplied in this kit are manufactured to metrology
standards in order to obtain the best measurement
accuracy specifications. If other connectors than these
precision adapters are used as the test ports, they must be
fully inspected. Using other than the highest quality
connectors as the test ports will reduce accuracy and
repeatability as well as possibly damaging the calibration
standards.
Precision Connectors
For general use, any 3.5 mm precision
female con-
nector can be used for the female test port. The 3.5 mm
precision male connector used on the male end of these
adapters is always required for measurements between
7-32
in order to connect the 7-32
air line in this
kit. Any 3.5 mm precision male connector can be used at
frequencies less than 7
Feature
The precision adapter male connector has a special feature
to allow installation of the 7-32 air line.

Grasp the knurled sleeve and move the nut to its
extended position by pulling on it.
This is the position used for measurement of the 7-32
air line.

. Now move the sleeve forward and push the nut back
into its standard position.
This position is used to install the short air line, for
connecting the other calibration standards, and for
connecting the device under test.
