4.Error Messages Abbreviated error messages are reported in this space. When

Area

multiple error messages occur, only the most recent message

 

remains displayed. All of the reported error messages with details

 

can be viewed by pressing Utility > Error Info >

 

View Next Error Message.

5. Text Area

This area is used to display status information about the signal

 

generator such as the modulation status, to enter information such

 

as creating sweep lists, and to manage information such as

 

displaying the catalog of files and deleting unwanted files.

6.Active Entry The current active function is shown in this area. For example, if

Area

frequency is the active function, the current setting will be

 

displayed in the active entry area and that setting will change as

 

you enter a new value.

7.Annunciators The display annunciators show the status of some of the signal generator functions and indicate error conditions of the instrument. The following annunciators are available:

φM

This annunciator appears when phase modulation is turned on.

ALC OFF

This annunciator appears when the automatic leveling control

 

(ALC) circuit is disabled.

AM

This annunciator appears when amplitude modulation is turned on.

ARMED

This annunciator appears when a sweep has been initiated and the

 

signal generator is waiting for the sweep trigger event.

ATTEN HOLD

This annunciator appears when the attenuator hold function is

 

turned on. When this function is on, the attenuator is frozen at its

 

current setting.

BERT

This annunciator appears whenever the Option UN7, bit error rate

 

test (BERT), or Option 300, base station BERT extension, functions

 

are turned on.

Digital

An annunciator appears here when a digital modulation is on.

Modulation

The exact annunciator depends on the modulation type, and is

Annunciators

documented in the manual that addresses that modulation.

 

Only one modulation con be on at a time, so sharing an annunciator

 

location is not a problem.
