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/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 Agilent/Keysight Technologies logo is not displayed refer to the “No
Agilent/Keysight Splash Screen Displayed” section in this chapter. If the
instrument hangs at the Agilent/Keysight Technologies splash screen refer
to the “Instrument Hangs at the Agilent/Keysight Splash Screen” section
in this chapter.
6. Verify text is displayed on screen where the user has the option of booting
Windows or running the Agilent Recovery System. The default selection is
to boot Windows. 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 will begin to boot. If the Windows 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 operating system will
begin to boot up. This will take ~20-30 seconds.
8. The Agilent/Keysight 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 EXA Spectrum Analyzer
application begins loading. The N9010A 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 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.
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 329 in this manual.
