Is there power at the receptacle?
Is the analyzer turned on? Check to see if the green LED beside the power switch
is on. Also, listen for internal fan noise to determine if the analyzer cooling fans
are running.
If other equipment, cables, and connectors are being used with your signal
analyzer, make sure they are connected properly and operating correctly.
Is the Measurement Application running? If not, there is a software launch
shortcut/icon on the desktop.
Does the instrument application have the focus? (That is, is the blue window
banner highlighted?) If not, move focus to the application with Alt-Tab.
Review the measurement procedures being performed when the problem first
appeared. Are all of the settings correct?
If the analyzer is not functioning as expected, return the analyzer to a known state
by pressing Mode Preset.
Is the measurement being performed, and the results that are expected, within the
specifications and capabilities of the analyzer?
Refer to the specifications guide for your analyzer.

Technical manual pdf files are available on the documentation DVD provided
with the analyzer, and on the Keysight website:

If the analyzer is not communicating via the LAN connection, check for the
presence of blinking yellow LEDs on the rear panel LAN connector. If the ACT
LED is not blinking, check the LAN cable and LAN integrity.
To meet specifications, the analyzer must be aligned. Either the Auto Align (On)
feature must be selected (press System, Alignments, Auto Align, Normal), or
the analyzer must be manually aligned.
Perform an Alignment. Press System, Alignments, Align Now, All.
If the previously performed alignments did not resolve the problem, press
System, Alignments, Restore Align Defaults. Then press System, Alignments,
Align Now, All.
