Before Calling Agilent Technologies

Check the Basics

Is there power at the receptacle?

Make sure there is no disk in the front-panel disk drive.

Is the analyzer turned on? Check to see if the green LED above the power switch is on. Also, listen for internal fan noise to determine if the analyzer cooling fans are running.

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).

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.

If the analyzer is not communicating via the LAN connection, check for the presence of blinking yellow LEDs on the rear panel LAN connector. If the Rx (receive) LED is not blinking, check the LAN cable and LAN integrity.

The analyzer must be powered on with the LAN already connected in order to recognize the LAN port.

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 24 hours, 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.
