[SOURce:]FREQuency2
[:CW | :FIXed]
[SOURce:]FREQuency2[:CW|:FIXed] <frequency> selects the sample rate for
arbitrary waveforms or the frequency for the standard waveforms (square, ramp,
triangle).

Arbitrary Waveforms: MINimum selects the current reference oscillator frequency
divided by 131,072; MAXimum selects the current reference oscillator frequency.
Square Wave Outputs: MINimum selects the current reference oscillator frequency divided
by 524,288; MAXimum selects the current reference oscillator frequency divided by 4.
Ramps and Triangles Outputs: MINimum selects the current reference oscillator frequency
divided by 131,072 further divided by the SOURce:RAMP:POINts value; MAXimum selects
the current reference oscillator frequency divided by the SOURce:RAMP:POINts value.
The above values bound the valid range for <frequency>. The <frequency> value is
rounded to the nearest frequency that can be produced using the divide-by-n technique of
this generator.
Comments • If the actual frequency generated differs from the specified frequency by greater
than 1%, the Frequency bit of the Questionable Signal Status Register will be set.
See the STATus subsystem for more information.
