Troubleshooting
Check the Basics
Check the Basics
o Is there power at the receptacle? 
o Is the instrument 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 instrument 
cooling fans are running. 
o If other equipment, cables, and connectors are being used with your EMI 
Receiver, make sure they are connected properly and operating correctly. 
If the instrument cannot completely load or run the operating system, or the 
instrument application is not successfully launched, the problem could be a 
corrupt hard drive. If the instrument gets far enough along in the boot process to 
run the "Agilent Recovery System", perform the Disk Drive Recovery Process as 
described on page 68. 
o Is the Measurement Application running? If not, there is a software launch 
shortcut/icon on the desktop.
o 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.
o Review the measurement procedures being performed when the problem first 
appeared. Are all of the settings correct? 
o If the instrument is not functioning as expected, return the instrument to a known 
state by pressing Mode Preset.
NOTE Some instrument settings are not affected by a Preset. If you wish to reset the 
instrument settings, press System, Power On, Restore Power On Defaults.
o Is the measurement being performed, and the results that are expected, within the 
specifications and capabilities of the instrument? Refer to the specifications guide 
for your instrument. Technical manual pdf files are available on the Agilent 
website:

o If the instrument 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.
o To meet specifications, the instrument must be aligned. Either the Auto Align 
(On) feature must be selected (press System, Alignments, Auto Align, Normal), 
or the instrument must be manually aligned. 
o Perform an Alignment. Press System, Alignments, Align Now, All. 
o Perform an RF Preselector Alignment. Press System, Alignments, More 1 of 2, 
RF Preselector, Align Now, 20 Hz to 3.6 MHz.
