The following is an overview of the steps required to generate an FSK modulated
waveform.
Enable FSK
Modulation
Configure Carrier
Select FSK
Source
Select FSK HOP
Frequency
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.

other modulation modes will be disabled when FSK
modulation is enabled.
Syntax SOURce[1|2]:FSKey:STATe {OFF|ON}
Example SOUR1:FSK:STAT ON
Enables FSK modulation
