8-9. Amplitude Modulation (AM) Commands
8-9-1. AM Overview
To successfully create an AM waveform, the following commands must be
executed in order.
Enable AM
Modulation
Configure Carrier
Select Modulation
Source
Select Shape
Set Modulating
Frequency
Set Modulation
Depth
1.
Turn on AM modulation using the SOURce[1|2]:
AM:STAT ON command
2.
Use the APPLy command to select a carrier waveform.
Alternatively the equivalent FUNC, FREQ, AMPl, and
DCOffs commands can be used to create a carrier
waveform with a designated frequency, amplitude and
offset.
3.
Select an internal or external modulation source using
the SOURce[1|2]:AM:SOUR command.
4.
Use the SOURce[1|2]:AM:INT:FUNC command to select
a sine, square, upramp, dnramp or triangle modulating
waveshape. For internal sources only.
5.
Set the modulating frequency using the SOURce[1|2]:
AM:INT:FREQ command. For internal sources only.
6.
Set the modulation depth using the SOURce[1|2]:
AM:DEPT command.
