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.
