General Safety Considerations
Warning w Before this instrument is switched on, make sure it has been
properly grounded through the protective conductor of the ac
power cable to a socket outlet provided with protective earth
contact.
n Any interruption of the protective (grounding) conductor,
inside or outside the instrument, or disconnection of the
protective earth terminal can result in personal injury.
n If this instrument is used in a manner not specified by
Hewlett-Packard Co., the protection provided by the instrument
may be impaired.
n There are many points in the instrument which can, if
contacted, cause personal injury. Be extremely careful. Any
adjustments or service procedures that require operation of
the instrument with protective covers removed should be
performed only by trained service personnel.
Caution Before this instrum,ent is switched on, make sure its primary power
circuitry has been adapted to the voltage of the ac power source.
Failure to set the ac power input to the correct voltage could cause
damage to the instrument when the ac power cable is plugged in.
This product conforms to Enclosure Protection IP 2 0 according to
IEC-529. The enclosure protects against finger access to hazardous
parts within the enclosure; the enclosure does not protect against the
entrance of water.

Initial Inspection Inspect the shipping container upon receipt. Retain it and the
cushioning materials. If the container or cushioning material is
damaged, verify that the contents are complete and that the analyzer
functions correctly mechanically and electrically.
If the contents are incomplete or the analyzer fails the verification
tests in the calibration guide, notify one of the Hewlett-Packard
Sales and Service Offices listed in `Pable 9-3. Show any container or
cushioning materials damages to the carrier. The Hewlett-Packard
Sales and Service Office will arrange for repair or replacement without
waiting for a claim settlement.
The shipping container and cushioning materials are shown in
the "If You Have A Problem" chapter, Figure 9-4. Instructions for
repackaging the analyzer are included in that chapter.

Quick Start Guide 1-3
Turning the Spectrum Analyzer On for the First Time
The spectrum analyzer requires no installation other than connection
to an ac power source. If you want to install your spectrum analyzer
into an HP System II cabinet or a standard 19 inch (486.2 mm)
equipment rack, complete instructions are provided with the
Option 908 and Option 909 Rack mounting Kits.
Caution Do not connect the analyzer to an ac power source before verifying
that the line voltage is correct, the line-voltage selector switch located
on the analyzer rear panel is set to the correct voltage, and the proper
fuse is installed. Failure to verify that these items are correct could
result in equipment damage.

Caution When installing the instrument in a cabinet, the convection into
and out of the instrument must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum
operating temperature of the instrument by 4 degrees C for every
100 watts of power dissipated in the cabinet. If the total power
dissipated in the cabinet is greater than 800 watts, then forced
convection must be used.
1-4 Quick Start Guide
1. Press (LINE] to turn the analyzer on.
2. The analyzer takes about half a minute to perform a series of
self-diagnostic and adjustment routines. At completion, the screen
displays the analyzer model number and the firmware date (for
example, 890802 indicates August 2, 1989). If you should ever need
to call Hewlett-Packard for service or have any questions regarding
your analyzer, it is helpful to know the firmware date to get the
most accurate information.
3. Allow the analyzer a 5-minute warmup. Refer to the warmup
specification in the calibration guide.
4. The reference level calibration adjustment procedure in this
chapter should be performed before checking the specifications.
5. The trace alignment procedure can be per
