Calibration Kit Components
Air Lines
The HP
3.5 mm Precision Calibration Kit contains
components useful for several different calibration tech-
niques. The parts used for the TRL 2-Port calibration are:
l
Longer precision air line for 2 to 7
l
Shorter precision air line for 7 to 32
l
Male and female short circuits
l
Male and female fixed loads
Other parts included are:
l

Tools
Note the reference card in the box and the material list on
the bottom of the box.
These are precision air lines. Each one is always stored in
its installation tool to help prevent damage and preserve
cleanliness.
The shorter air line is used for measurement calibration
over the 7 to 32
frequency range. The longer air line is
used for measurement calibration over the 2 to 7
range. Each air line is fully specified at all frequencies
within its stated range.
