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
User’s Guide for details.
• To meet specifications, the analyzer must be aligned. For
more information on how to align the analyzer, refer to
“Running Internal Alignments” on page 8.
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.
WARNING
No operator serviceable parts inside. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers.
