Output Function(continued)• The following matrix shows which output functions are allowed witheach modulation mode. Each “X” indicates a valid combination. If youchange to a function that is not allowed with the selected modulation,the modulation mode is turned off.• Front-Panel Operation: To select a function, press any key in the toprow of function keys. Press Arb to output the arbitrary waveformcurrently selected (to scroll through the waveform choices andmake a selection, press Arb List ).• To select dc volts from the front panel, press Offset and hold it downfor more than 2 seconds.• Remote Interface Operation:FUNCtion:SHAPe {SINusoid|SQUare|TRIangle|RAMP|NOISe|USER|DC}You can also use the APPLy command to select the function,frequency, amplitude, and offset with a single command.AM CarrierAM Modulating WaveFM CarrierFM Modulating WaveFSK ModulationBurst ModulationFrequency SweepSineXXXXXXXSquareXXXXXXXTriangleXXXXXXXRampXXXXXXXNoiseXXArbXXXXXXXChapter 3 Features and FunctionsOutput Configuration56
