FSK Overview
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]: FSK:STAT ON command.
2. Use the APPLy command to select a carrier
waveform. Alternatively, the FUNC, FREQ,
AMPL, and DCO commands can be used to
create a carrier waveform with a designated
frequency, amplitude and offset. The carrier
waveform can be sine, square or ramp.
3. Select an internal or external modulation
source using the SOURce[1]:FSK:SOUR
command.
4. Set the hop frequency using the
SOURce[1]:FSK:FREQ command.
5. Use the SOURce[1]: FSK:INT:RATE
command to set the FSK rate. The FSK rate
can only be set for internal sources.
SOURce[1]:FSKey:STATe
Set
Query
Description Turns FSK Modulation on or off. By default FSK
modulation is off.
Note
As only one mode is allowed at any one time,
other modes (AM, FM, Sweep etc.) will be disabled
when FSK modulation is enabled.
