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 co nfiguration probl em, the laser source is not able to
pass a wavelength sweep.
parameters: none
response: A string with a detailed descripti on of a configuration p roblem, or "OK" if t he sweep os con-
figured correctly. The responses shown below are all the possible configura tion problem
strings:
Message Description
368,LambdaStop
<=LambdaStart
start wavelength must be smaller th an 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 d ivided 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
example: sour0:wav:swe:chec? → "triggerNum > max"
affects: All tunable laser modules e xcept Agilent 81649A and A gilent 81689A/B
