FM Overview
The following is an overview of the steps required to generate an FM waveform.
The commands used for FM are listed on the next page.
1 Configure the carrier waveform.
2 Select the mod ulation source.
3 Select the shape of the mod ulating waveform.
4 Set the mod ulating frequency.
5 Set the peak frequency deviation.
6 Enable FM mod ulation.

"Frequency Modulation (FM)"
Use the APPLy command or the equivalent FUNC, FREQ, VOLT, and VOLT:OFFS
commands to select the function, frequency, amplitude, and offset of the
carrier waveform. You can select a sine or square waveform for the carrier
(ramp, pulse, noise, dc, and arbitrary are not allowed).
The function generator will accept an internal or external modulation source.
Select the modulation source using the FM:SOUR command. For an external
source, you can skip steps 3 and 4 below.
You can modulate the carrier with a sine, square, ramp, noise, or arbitrary
waveform (pulse and dc are not allowed). Use the FM:INT:FUNC command to
select the modulating waveshape.
Set the modulating frequency to any value from 2 mHz to 20 kHz using the
FM:INT:FREQ command.
Set the frequency deviation to any value from 1 mHz to 5 MHz using the
FM:DEV command.
After you have set up the other modulation parameters, use the
FM:STAT ON command to enable FM.
