4. Error Messages
Area
Abbreviated error messages are reported in this space. When
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
Area
The current active function is shown in this area. For example, if
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
Modulation
Annunciators
An annunciator appears here when a digital modulation is on.
The exact annunciator depends on the modulation type, and is
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.
