Frequency-Shift Keying (FSK) Modulation
You can configure the instrument to "shift" its output frequency between two preset values (called the "carrier
frequency" and the "hop frequency") using FSK modulation. The rate at which the output shifts between these two
frequencies is determined by the internal rate generator or the signal level on the front panel Ext Trig connector.
See Front Panel Menu Operation - Output an FSK Waveform for details on FSK using the front panel.
To Select FSK Modulation
– Only one modulation mode may be enabled at a time. Enabling FSK turns off the previous modulation mode.
– You cannot enable FSK when sweep or burst is enabled. Enabling FSK turns off sweep and burst.
– To avoid multiple waveform changes, enable modulation after configuring the other modulation parameters.

FSKey:STATe {OFF|ON}
FSK Carrier Frequency
The maximum carrier frequency varies by function, model, and output voltage, as shown here. The default is 1 kHz
for all functions other than arbitrary waveforms.
When a logic low is present, the carrier frequency is output. With a logic high, the hop frequency is output.
