Description This softkey (Option 002 only) accesses the frequency modulation softkeys. These softkeys engage external and internal frequency

modulation. They allow you to define the coupling, waveform, rate, and deviation of the internal FM.

FM an/Off	Ext	Toggles on and off the frequency
		modulation mode for an external FM
		source.
FM adaff	Int	Toggles on and off the frequency
		modulation mode using the internal
		FM generator.
Internal FM Rate		Sets the rate of the internal frequency
		modulation.

Internal FM Deviation

FM Coupling lOOk&

FM Coupling DC

Sets the deviation of the internal frequency modulation.

Sets AC coupling for modulation rates of 100 kHz or greater. The RF signal is phase locked.

Sets DC coupling for modulation rates of less than 100 kHz. The phase locked loop is open.

Waveform Menu	Displays	the waveforms for internal
	frequency	modulation.

Programming Codes SCPI: NONE, see the individual softkeys listed. Analyzer: NONE
