1. Turn on PM modulation using the
SOURce[1|2]: PM: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]:PM:SOUR command.
4. Use the SOURce[1|2]: PM: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]:PM:INT:FREQ command. For
internal sources only.
6. Use the SOURce[1|2]:PM:DEV command to set
the phase DEViation.
