1. Turn on SUM modulation using the

SOURce[1|2]: SUM:STATe ON command.

2. Use the APPLy command to select a carrier

waveform. Alternatively, the 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]:SUM:SOUR command.

4. Use the SOURce[1|2]: SUM: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]:SUM:INT:FREQ command. For
internal sources only.

6. Use the SOURce[1|2]:SUM:AMPL command to

set the modulating amplitude.
