7 In Case of Difficulty
Check the Basics
Before calling Agilent 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. For
details, refer to “Presetting the Spectrum Analyzer” on
page 27.
• 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 135.
• To meet specifications, the analyzer must be aligned. For
more information on how to align the analyzer, please
refer to “Running Internal Alignments” on page 22.
