Amplitude Modulation (AM) Commands
See also “Amplitude Modulation (AM)” starting on page 87 in Chapter 3.
AM Overview
The following is an overview of the steps required to generate an AM waveform.
The commands used for AM 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 AM: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
AM: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
AM:INT:FREQ command.
5 Set the modulation depth.
Set the modulation depth (also called “percent modulation”) to any value from
0% to 120% using the AM:DEPT command.
6 Enable AM modulation.
After you have set up the other modulation parameters, use the
AM:STAT ON command to enable AM.
