The application note, “Principles of Microwave Connector Care” (HP part number 5958-7442) can help
you improve measurements and reliability. Suggestions in the application note will help you get the best
performance from
all
microwave connectors.
It
will
show what
to
look for when cleaning and inspecting
connectors (in order
to
preserve their precision and extend their life) and how
to
make the best possible
microwave connections (improving the accuracy and repeatability of all your measurements).

Bench Mounting
The instrument cabinet
has
plastic feet and fold-away
tilt
stands
for convenience in bench operation.
(The plastic feet are shaped
to
ensure self-aligning of the instruments when stacked.) The tilt
stands
raise the front of the instrument for easier viewing of the front panel.
Rack Mounting
The Modulation Analyzer
is
heavy for its size
(23.6
kg,
52
lb). Care must be
exercised when lifting to avoid personal injuv. Use equipment slides when
rack mounting.
Rack
mounting information is provided with the rack mounting kits.
If
the kits were not ordered with
the instrument
as
options, they may be ordered through the nearest Hewlett-Packard office. (Refer
to paragraph 1-8,
Additional Equipment Information

Before
rack mounting the Modulation Analyzer, the
Operating Information
pull-out tray (attached
to
the
