Signal Generation – The SOURce Subsystem Measurement Operations & Settings
Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition 131
command:
[:SOURce[n]][:CHANnel[m]]:WAVelength[:CW[l]|:FIXED[l]]?
syntax: [:SOURce[n]][:CHANnel[m]:WAVelength[:CW[l]|:FIXED[l]]?[<wsp>[MIN|DEF|MAX]
description: Returns the wavelength value in meters.
parameters: none
Also allowed, for tunable laser
modules only, are
MIN: minimum wavelength
MAX: maximum wavelength
DEF: This is not the preset (*RST) default value but is half
the sum of, the minimum wavelength value and the maxi-
mum wavelength value
NOTE
Use [l] to query the upper or lower wavelength laser source of a dual-wavelength laser
source. The default value of [l] is 1, the lower wavelength source. The upper wavelength
source is denoted by 2.
response: The wavelength as a float value in meters.
example: sour0:wav? → +1.5672030E-006<END>
sour0:wav? min → +1.5500000E-006<END>
sour2:wav:fixed2? → +1.61544494E-006<END>
Returns the current wave-
length value for a tunable la-
ser module.
Returns minimum wave-
length for a tunable laser
module.
Returns the wavelength val-
ue of the upper wavelength
source of a dual-wavelength
laser source.
affects: All laser source, DFB source, and tunable laser modules and return loss modules with an in-
ternal source
command:
[:SOURce[n]][:CHANnel[m]]:WAVelength:CORRection:ARA
syntax: [:SOURce[n]][:CHANnel[m]]:WAVelength:CORRection:ARA
description: Realigns the laser cavity.
parameters: none
response: none
example: sour0:wav:corr:ara
affects: All tunable laser modules except Agilent 81649A and Agilent 81689A/B
