Text Area 7. Softkey Label Area1. Active Function AreaThis area displays the currently active function. For example, if frequency is the active function, thecurrent frequency setting appears. If the currently active function has an increment value associatedwith it, that value also appears.2. Frequency AreaThis area displays the current frequency setting.3. AnnunciatorsAnnunciators show the status of some of the signal generator functions, and indicate errorconditions. An annunciator position may be used by more than one annunciator; in this case, onlyone of the functions sharing a given position can be active at a given time.This annunciator appears when...ΦMARBALC OFFAMARMEDATTNHOLDAWGNPhase modulation is on. If you turn frequency modulation on, the FM annunciator replaces ΦM.The ARB generator is on. ARB is running and not waiting on a trigger.The ALC circuit is disabled. The UNLEVEL annunciator appears in the same position if the ALC is enabled andis unable to maintain the output level.Amplitude modulation is on.A sweep has been initiated and the signal generator is waiting for the sweep trigger event.The attenuator hold function is on. When this function is on, the attenuator is held at its current setting.Real Time I/Q Baseband additive white Gaussian noise is on.Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 11
