[:SOURce[n]][:CHANnel[m]]:WAVelength:FREQuency<wsp><value>
[THZ|GHZ|MHZ|KHZ|HZ]
Sets the frequency difference used to calculate a relative wavelength. The output wave-
length is made up of the reference wavelength and this frequency difference.
The default units for frequency are Hertz.
The output wavelength (λ) is set from the base wavelength (λ
(df). The formula for calculating the output wavelength is:
where c is the speed of light in a vacuum (2.990 x 10
The frequency difference is a float value in Hz.
