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.

none

A string with a detailed description of a configuration problem, or "OK" if the sweep os con- figured correctly. The responses shown below are all the possible configuration problem strings:

Message

Description

368,LambdaStop

start wavelength must be smaller than stop wavelength

<=LambdaStart

 

 

 

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

The only allowed modulation source with the lambda logging function is

AND Modulation = On

coherence control.

AND ModulationSource!

 

= CoherenceControl

 

 

 

375,LambdaLogging = On

lambda logging only works "Step Finished" output trigger configuration

AND TriggerOut! =

 

StepFinished

 

 

 

376,Lambda logging in

lambda logging can only be done in continuous sweep mode

stepped mode

 

 

 

377,step not multiple of

the step size must be a multiple of the smallest possible step size

<x>

 

378, triggerFreq < min the number of triggers exceeds the allowed limit

sour0:wav:swe:chec? → "triggerNum > max"
