Blank Display
If your display is blank, before calling Agilent Technologies or returning
the analyzer for service, please make the checks listed below. The
"Power Requirements" section includes more detailed information
about making these checks.
• Is the analyzer plugged into the proper ac power source? Does the
line socket have power?
• Is the rear-panel voltage selector switch set correctly?
• Is the line fuse good?
• Is the analyzer turned on?
• Check that the LED over the power switch is lit and the fan is on. If
the spectrum analyzer has power applied but the display is still
blank, you may have a hardware failure. See "Servicing the
Spectrum Analyzer Yourself" in this chapter.
Check the Basics
Unexpected behavior can have many different causes. Perform the
checks below and then refer to the list of symptoms and suggestions.
These checks may eliminate the problem altogether, or may give a
clearer idea of its cause. If you determine that there is a hardware
problem refer to the "Hardware Problems" section.
• If other equipment, cables, and connectors are being used with the
spectrum analyzer, are they connected properly and operating
correctly?
• Often problems may be solved by repeating what was being done
when the problem occurred.
