Signal Generator OverviewBlank Front Panel Display – N5161A/62A MXG ATE5. Error Message AreaThis area displays abbreviated error messages. If multiple messages occur, only the most recentmessage remains displayed. See “Reading Error Messages” on page 75.6. Text AreaThis area displays signal generator status information, such as the modulation status, and otherinformation such as sweep lists and file catalogs. This area also enables you to perform functionssuch as managing information (entering information, and displaying or deleting files).7. Softkey Label AreaThis area displays labels that define the function of the softkeys located immediately to the right ofthe display. Softkey labels change, depending on the function selected.Blank Front Panel Display – N5161A/62A MXG ATEN5161A/62A MXG ATE – Web Enabled DisplayThe 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 ProgrammingGuide.AnnunciatorsNOTEOn the N5161A/62A, the following listing of annunciators are only displayed and visiblethrough 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 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 OFFAMARMEDATTNHOLDBBG DACDETHTRAWGNPhase 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.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).The ALC detector heater is not up to temperature. To meet ALC specifications the heater must be attemperature.Real Time I/Q Baseband additive white Gaussian noise is on.Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 13
