Measurement Operations & Settings Signal Generation – The SOURce Subsystem
144 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
command:
[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:STARt
syntax: [:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:STARt<wsp><start value>
[PM|NM|UM|MM|M]
description: Sets the starting point of the sweep.
NOTE
Cannot be set while a sweep is running.
parameters: The wavelength at which the sweep starts as a float value.
If you specify no units in your command, meters are used as the default.
response: none
example: wav:swe:star 1500nm
affects: All tunable laser modules
command:
[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:STARt?
syntax: [:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:STARt?[<wsp>MIN|MAX]
description: Returns the starting point of the sweep.
parameters: optional MIN Returns the minimum start wavelength available.
This value is wavelength dependent.
MAX Returns the maximum start wavelength available.
This value is wavelength dependent.
response: The wavelength at which the sweep starts as a float value in meters.
example: wav:swe:star? → +1.50000000E-006<END>
affects: All tunable laser modules
command:
[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:STOP
syntax: [:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:STOP<wsp><stop value>
[PM|NM|UM|MM|M]
description: Sets the end point of the sweep.
NOTE
Cannot be set while a sweep is running.
parameters: The wavelength at which the sweep ends as a float value in meters.
If you specify no units in your command, meters are used as the default.
response: none
example: wav:swe:stop 1550nm
affects: All tunable laser modules
