a designated frequency, amplitude and offset.
Sine, square or ramp can be used as the
carrier wave.
3. Select an internal or external modulation
source using the SOURce[1]:AM:SOUR
command.
4. Use the SOURce[1]:AM:INT:FUNC command
to select a Sine, Square or Ramp modulating
waveform. For internal sources only.
5. Set the modulating frequency using the
SOURce[1]:AM:INT:FREQ command. For
internal sources only.
6. Set the modulation depth using the
SOURce[1]:AM:DEPT command.
