Boot Up and Initialization Troubleshooting
Instrument Boot Up Process
4. The instrument fans should start running. The fans are mounted on the
left-hand side of the analyzer and draw air into the instrument to cool the
internal circuitry. If a fan is not running refer to the “Fan(s) Are Not
Operating” section in this chapter.
5. The Keysight Technologies splash screen is displayed in white font on a
dark background for ~5-10 seconds after the analyzer is turned on. If the
Keysight Technologies logo is not displayed refer to the “No Keysight
Splash Screen Displayed” section in this chapter. If the instrument hangs
at the Keysight Technologies splash screen refer to the “Instrument Hangs
at the Keysight Splash Screen” section in this chapter.
6. Verify text is displayed on screen where the user has the option of booting
Windows 7 FES or running the Instrument Recovery System. The default
selection is to boot Windows 7 FES. If a recovery is required, press the
Down Arrow key on the front panel of the analyzer within 5 seconds to
highlight “Instrument Recovery System” and press the Enter key on the
analyzer, otherwise Windows 7 FES will begin to boot. If the Windows 7
FES boot screen is not displayed within a few seconds refer to the
“Instrument Cannot Completely Load or Run the Operating System”
section in this chapter.
7. If the recovery system is not selected the Windows 7 FES operating
system will begin to boot up. This will take ~20-30 seconds.
8. The Keysight Technologies logo is displayed in white font on a black
background while Windows finishes loading user preferences. This can
take up to 4 minutes. If this does not occur refer to the “Instrument Cannot
Completely Load or Run the Operating System” section in this chapter.
9. By default, the initialization process of the EXA Spectrum Analyzer
application begins loading. The N9010B EXA Signal Analyzer screen
appears. The screen remains for slightly over 1 minute. If any of the
initializing processes do not complete, refer to the “Initializations Did Not
Complete” section in this chapter.
10.While the application software is loading the instrument will perform a
number of internal alignments before the analyzer begins to sweep. A
screen with a black background appears and the alignment progress is
shown in a gray box. The number of alignments is dependent on which
hardware options are present. If an alignment fails, refer to the “Fails an
Initial Alignment” section in this chapter.
11.If any of the initial alignments fail, check the alignment history for
troubleshooting hints.
The instrument alignment history can be found at:
If a recovery was selected follow the on-screen instructions and perform a
system recovery. Additional information about performing a system
recovery can be found in Chapter 9, “CPU/Disk Drive Troubleshooting”, on
page 325 in this manual.
