Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 13
Preliminary Signal Generator Overview
Preliminary Blank Front Panel Display – N5161A/62A MXG ATE
6. Text Area
This area displays signal generator status information, such as the modulation status, and other
information such as sweep lists and file catalogs. This area also enables you to perform functions
such as managing information (entering information, and displaying or deleting files).
7. Softkey Label Area
This area displays labels that define the function of the softkeys located immediately to the right of
the display. Softkey labels change, depending on the function selected.

N5161A/62A MXG ATE – Web Enabled Display
The MXG ATE only has display information available through a LAN connection to the Web Server
(“11. LAN” on page 17). For more information on the Web–Enabled MXG, refer to Programming
Guide.
Annunciators
NOTE On the N5161A/62A, the following listing of annunciators are only displayed and visible
through the Web–Enabled MXG. Refer to Programming Guide, “Using the Web Browser”.
Annunciators show the status of some of the signal generator functions, and indicate error
conditions. An annunciator position may be used by more than one annunciator; in this case, only
one of the functions sharing a given position can be active at a given time.
This annunciator appears when...
ΦM Phase modulation is on. If you turn frequency modulation on, the FM annunciator replaces ΦM.
ARB The ARB generator is on.
ALC OFF The ALC circuit is disabled. The UNLEVEL annunciator appears in the same position if the ALC is enabled and
is unable to maintain the output level.
AM Amplitude modulation is on.
ARMED A sweep has been initiated and the signal generator is waiting for the sweep trigger event.
ATTNHOLD The attenuator hold function is on. When this function is on, the attenuator is held at its current setting.
BBG DAC A DAC overflow is occurring, adjust the runtime scaling adjust until the BBG DAC annunciator turns off.
Another annunciator, UNLOCK, appears in the same position and has priority over the BBG DAC annunciator
(see UNLOCK, below).
DETHTR The ALC detector heater is not up to temperature. To meet ALC specifications the heater must be at
temperature.
AWGN Real Time I/Q Baseband additive white Gaussian noise is on.
DIGBUS The digital bus is in use.
DIGMOD Custom Arb waveform generator is on.
ERR An error message is placed in the error queue. This annunciator does not turn off until you either view all of
the error messages or clear the error queue (see “Reading Error Messages” on page 74).
EXTREF An external frequency reference is applied.
