command: [:SOURce[n]][:CHANnel[m]]:WAVelength:REFerence[l]?
syntax: [:SOURce[n]][:CHANnel[m]]:WAVelength:REFerence[l]?
description: Returns the reference wavelength (λ
0
).
parameters: none
response: The wavelength as a float value in meters.
example: sour2:wav:ref?
-> +1.5500000E-006<END>
affects: All tunable laser and DFB modules
command: [:SOURce[n]][:CHANnel[m]]:WAVelength:REFerence:DISPlay
syntax: [:SOURce[n]][:CHANnel[m]]:WAVelength:REFerence:DISPlay
description: Sets the reference wavelength to the value of the output wavelength (λ -> λ
0
), that is, sets the frequency offset (df) to
zero.
parameters: none
response: none
example: sour2:wav:ref:disp
affects: All tunable laser and DFB modules
