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.
