1. Turn on FSK modulation using the
SOURce[1|2]: FSK:STAT 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]:FSK:SOUR command.
4. Set the hop frequency using the
SOURce[1|2]:FSK:FREQ command.
5. Use the SOURce[1|2]: FSK:INT:RATE
command to set the FSK rate. The FSK rate can
only be set for internal sources.
