Digital Modulation Annunciators | Agilent Technologies E8257D PSG

	Signal Generator Overview
	Front Panel Display
UNLEVEL	This annunciator appears when the signal generator is unable to maintain the
	correct output level. The UNLEVEL annunciator is not necessarily an indication of
	instrument failure. Unleveled conditions can occur during normal operation. A
	second annunciator, ALC OFF, will appear in the same position when the ALC
	circuit is disabled.
UNLOCK	This annunciator appears when any of the phase locked loops are unable to
	maintain phase lock. You can determine which loop is unlocked by examining the
	error messages.

4. Digital Modulation Annunciators

All digital modulation annunciators (E8267D with Option 601/602 only) appear in this location. These annunciators appear only when the modulation is active, and only one digital modulation can be active at any given time.

5. Amplitude Area

The current output power level setting is shown in this portion of the display. Indicators are also displayed in this area when amplitude offset is used, amplitude reference mode is turned on, external leveling mode is enabled, a source module is enabled, and when user flatness is enabled.

6. Error Message Area

Abbreviated error messages are reported in this space. When multiple error messages occur, only the most recent message remains displayed. Reported error messages with details can be viewed by pressing Utility > Error Info.

7. Text Area

This text area of the display:

•shows signal generator status information, such as the modulation status, sweep lists, and file catalogs

•displays the tables

•enables you to perform functions such as managing information, entering information, and displaying or deleting files

8. Softkey Label Area

The labels in this area define the function of the softkeys located immediately to the right of the label. The softkey label may change depending upon the function selected.
