Check the Basics
Before calling Keysight Technologies, or returning an analyzer for
service, perform the quick checks listed below. This check may
eliminate the problem.
• Is there power at the receptacle?
• Is the analyzer turned on? Listen for internal fan noise to
determine if the analyzer cooling fan is running. Feel the rear
side of the analyzer for air flow.
• If other equipment, cables, and connectors are being used with
your spectrum analyzer, make sure they are connected properly
and operating correctly.
• Review the measurement procedures being performed when the
problem first appeared. Make sure all of the settings are correct.
• If the analyzer is not functioning as expected, return the
analyzer to a known state by pressing
Preset
.
• Is the measurement being performed, and the results that are
expected, within the specifications and capabilities of the
analyzer? Refer to the
Technical Overview
for your analyzer.
• Is the analyzer displaying an error message? If so, refer to
"Instrument Messages" on page 173
for details.
• To meet specifications, the analyzer must be aligned. For more
information on how to align the analyzer, refer to

NOTE
Some analyzer settings are not affected by a Preset. If you wish to reset the
analyzer configuration to the state it was in when it was originally sent from
the factory, press System, Power On/Preset, Preset Type, Factory. Then
press the green Preset key on the front panel.
