command: [:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:CHECkparams?
syntax: [:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:CHECkparams?
description: Returns whether the currently set sweep parameters (sweep mode, sweep start, stop, width, etc.) are consistent. If there is a
sweep configuration problem, the laser source is not able to pass a wavelength sweep.
parameters: none
response: A string with a detailed description of a configuration problem, or "OK" if the sweep os configured correctly. The responses
shown below are all the possible configuration problem strings:
Message Description
368,LambdaStop <=LambdaStart start wavelength must be smaller than stop wavelength
369,sweepTime < min the total time of the sweep is too small
370,sweepTime > max the total time of the sweep is too large
371,triggerFreq > max the trigger frequency (calculated from sweep speed divided by sweep step) is too
large
372,step < min step size too small
373,triggerNum > max the number of triggers exceeds the allowed limit
374,LambdaLogging = On AND
Modulation = On AND
ModulationSource! =
CoherenceControl
The only allowed modulation source with the lambda logging function is coherence
control.
375,LambdaLogging = On AND
TriggerOut! = StepFinished
lambda logging only works "Step Finished" output trigger configuration
376,Lambda logging in stepped
mode
lambda logging can only be done in continuous sweep mode
377,step not multiple of <x> the step size must be a multiple of the smallest possible step size
378, triggerFreq < min the number of triggers exceeds the allowed limit
379, Continuous Sweep AND
Modulation = On
379,Continuous Sweep = On for 81602A, 81606A, 81607A, 81608A, 81609A
example: sour0:wav:swe:chec?
-> "triggerNum > max"
affects: All tunable laser modules except Keysight 81649A, Keysight 81689A/B, and 81950A.
