Command: :SOURce0:WAVelength:CORRection:ARA
Syntax: :SOURce0:WAVelength:CORRection:ARA
Description: Realigns the laser cavity.
Parameters: None
Response: None
Example: :sour0:wav:corr:ara
Affects: All N777xC tunable laser sources
Command: :SOURce0:WAVelength:CORRection:ZERO
Syntax: :SOURce0:WAVelength:CORRection:ZERO
Description: Executes a wavelength zero.
Parameters: None
Response: None
Example: :sour0:wav:corr:zero
Affects: All N777xC tunable laser sources
Command: :SOURce0:WAVelength:FREQuency
Syntax: :SOURce0:WAVelength:FREQuency<wsp><value> [THZ|GHZ|MHZ|KHZ|HZ]
Description: Sets the frequency difference used to calculate a relative wavelength. The output wavelength is made up of the reference
wavelength and this frequency difference.
The default units for frequency are Hertz.
The output wavelength[l] is set from the base wavelength (l0) and the frequency offset (df).
The formula for calculating the output wavelength is:
where c is the speed of light in a vacuum (2.990 x 108 ms-1)
