CAUTION
Safety Notice
Safety Notice
Read the following warnings and cautions carefully before
powering on the spectrum analyzer to ensure personal and
instrument safety.
Always use a well-grounded, three-pin AC power cord to connect
to power source. Personal injury may occur if there is any
interruption of the AC power cord. Intentional interruption is
prohibited. If this product is to be energized via an external auto
transformer for voltage reduction, make sure that its common
terminal is connected to a neutral (earthed pole) of the power
supply.
Personal injury may result if the spectrum analyzer covers are
removed. There are no operator-serviceable parts inside. To avoid
electrical shock, refer servicing to qualified personnel.
14
Electrical shock may result if the spectrum analyzer is connected
to the power supply while cleaning. Do not attempt to clean
internally.
Prevent damage to the instrument and ensure protection of the
input mixer by limiting average continuous power input to +33
dBm, DC voltage to 50 VDC with >
Instrument damage may result if these precautions are not
followed.
To install the spectrum analyzer in other racks, note that they may
promote shock hazards, overheating, dusting contamination, and
inferior system performance. Consult your Keysight customer
engineer about installation, warranty, and support details.

Power Requirements
AC Power Cord
Getting Started
Power Requirements
The spectrum analyzer has an auto-ranging line voltage input. The
AC power supply must meet the following requirements:
Voltage: 100 to 240 VAC (90 to 264 VAC)
Frequency: 50 to 60 Hz
Power: Maximum 100 W
The analyzer is equipped with a three-wire power cord, in
accordance with international safety standards. This cable grounds
the analyzer cabinet when connected to an appropriate power line
outlet. The cable appropriate to the original shipping location is
included with the analyzer.
Various AC power cables are available that are unique to specific
geographic areas. You can order additional AC power cables for
use in different areas. The table AC Power Cords lists the available
AC power cables, the plug configurations, and identifies the
geographic area in which each cable is appropriate.
The detachable power cord is the product disconnecting device. It
disconnects the mains circuits from the mains supply before other
parts of the product. The front panel switch is only a standby
switch and do not disconnect instrument from LINE power.

Self-initialization takes about 25 seconds; the spectrum analyzer
then defaults to the menu mode. After power on, let the spectrum
analyzer warm up for 45 minutes for stabilization.
The front panel switch is a standby switch only; it is not a

Running Internal Alignments
Check for Instrument Messages
To meet the instrument performance specifications, the analyzer
must periodically be manually aligned.
1 Connect a BNC cable with the N-BNC adapter between the CAL
OUT and RF IN front panel connectors.
2 After 15-minute warm up, press > Alignment > Align > All
The self alignment takes about 5 minutes.
When an alignment is being run, there will be an audible
clicking sound as the attenuator settings are changed. This
sound is not an indication of a problem.
Please refer to
"Alignment" on page 159 for further information.
The spectrum analyzer has two categories of instrument messages:
error and warning messages. A error message is triggered by
operation errors, for example, parameter setting conflicts or data
input that is out of the range of a parameter. An warning message
may be triggered by hardware defects which could result in
damage to instrument.
Here are some tips to check the instrument messages.
1 Check the display to see if any messages display in the status bar.
Press > More > Show Errors to review each message. Refer to
Chapter 5, "Instrument Messages" for detailed system message
descriptions.
2 When you have reviewed and resolved all of the error messages,
press > More > Show Errors > Clear error queue to delete the
messages.
3 Cycle the power to the analyzer and re-check to see if the
instrument messages are still there.
