Set FSK Rate
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.
