In Case of Difficulty

Before Calling Agilent Technologies

Check the Basics

❏ Is there power at the receptacle?

❏ Is the analyzer turned on? Listen for internal fan noise to determine if the analyzer

cooling fan is running. Feel the right side of the analyzer to feel for air flow.

❏ If other equipment, cables, and connectors are being used with your spectrum analyzer,

make sure they are connected properly and operating correctly.

❏ 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

Preset, and Factory Preset (if displayed).

NOTE Some analyzer settings are not affected by a Preset. If you wish to reset the

analyzer configuration to the state it was in when it was originally sent from

the factory, press

System, Power On/Preset, Preset Type, Factory. Then press

the green Preset key on the front panel.

❏ 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.

❏ To meet specifications, the analyzer must be aligned. Either the Auto Align (On) feature

must be selected (press

System, Alignments, Auto Align, On), or the analyzer must be

manually aligned at least once every hour (see your specifications guide for more

information), or whenever the temperature changes more than 3°C. When

Auto Align,

On is selected, the AA screen annotation appears on the left edge of the display.
