To Set the Frequency Deviation
The frequency deviation is the deviation of the frequency of the modulating
waveform relative to that of the carrier waveform and the unit is Hz.
Press Deviation to set the FM frequency deviation.
Use the numeric keyboard or knob to input the desired frequency value.
For different carrier frequencies, the maximum frequency deviations are
different.
To Select the Modulation Waveform
Press Source to select "Int" modulation source; use the menu page up/down key
to open the 2/2 page of the menu; press Waveform to select "Sine" or
"Square" and the default is "Sine".

disabled.
To Set the Modulation Frequency
Press Source to select "Int" modulation source; press Rate to set the modulation
frequency.
Use the numeric keyboard or knob to input the desired frequency value.
For sine waveforms, the range of the modulation frequency is from 10 Hz to 100
kHz.
For square waveforms, the range of the modulation frequency is from 10 Hz to
20 kHz.
Note: When "Ext" modulation source is selected, this menu is grayed out and
