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 Agilent Technologies splash screen is displayed in white font on a 
dark background for ~5-10 seconds after the analyzer is turned on. If the 
Agilent Technologies logo is not displayed refer to the “No Agilent Splash 
Screen Displayed” section in this chapter. If the instrument hangs at the 
Agilent Technologies splash screen refer to the “Instrument Hangs at the 
Agilent Splash Screen” section in this chapter.
6. Verify text is displayed on screen where the user has the option of booting 
Windows XP or running the Agilent Recovery System. The default 
selection is to boot Windows XP. If a recovery is required, press the Down 
Arrow key on the front panel of the analyzer within 5 seconds to highlight 
“Agilent Recovery System” and press the Enter key on the analyzer, 
otherwise Windows XP will begin to boot. If the Windows XP 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 XP Professional 
operating system will begin to boot up. This will take ~20-30 seconds.
NOTE 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 8, “CPU/Disk Drive Troubleshooting”, on page  305 in 
this manual.
8. The Agilent Technologies logo is displayed in white font on a blue 
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 MXA Spectrum Analyzer 
application begins loading. The N9020A MXA 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 yellow 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.
