:FSKey
[SOURce:]FREQuency[1]:FSKey <frequency1>,<frequency2> sets the two
sample rates or waveform frequencies for frequency-shift keying.
[SOURce:]FREQuency[1]:FSKey:SOURce sets the source which selects between the
two sample rates or waveform frequencies. A TTL high level on the selected source
generates frequency1; a TTL low level generates frequency2.

numeric see below | MINimum | MAXimum Hz
MINimum selects 0 Hz.
Arbitrary Waveforms and Sine Wave Outputs: MAXimum selects the current reference
oscillator frequency divided by 4.
Square Wave Outputs: MAXimum selects the current reference oscillator frequency
divided by 16.
Ramps and Triangle Outputs: MAXimum selects the current reference oscillator
frequency divided by 4 further divided by the [SOURce:]RAMP:POINts value.
For non-sine wave outputs, multiply the MAXimum value by 2 if frequency doubling is in
effect (see the [SOURce:]FREQuency[1]:RANGe command).
The above values bound the legal range for <
frequency1> and <frequency2>.
Comments • Executable when Initiated: Yes. However, the frequency being generated will
not change until the FSK control source changes levels.
• Coupling Group: Frequency
