Frequency Modulation (FM) Commands
See also “Frequency Modulation” starting on page 77 in chapter 3.
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.
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).
2 Select the modulation source.
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.
3 Select the shape of the modulating waveform.
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.
4 Set the modulating frequency.
Set the modulating frequency to any value from 2 mHz to 20 kHz using
the
FM:INT:FREQ
command.
5 Set the peak frequency deviation.
Set the frequency deviation to any value from 1 mHz to 5 MHz using the
FM:DEV
command.
6 Enable FM modulation.
After you have set up the other modulation parameters, use the
FM:STAT ON
command to enable FM.
