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:

Description
start wavelength must be smaller than stop wavelength
the total time of the sweep is too small
the total time of the sweep is too large
the trigger frequency (calculated from sweep speed divided by sweep step) is too
large
step size too small
the number of triggers exceeds the allowed limit
The only allowed modulation source with the lambda logging function is coherence
control.
lambda logging only works "Step Finished" output trigger configuration
lambda logging can only be done in continuous sweep mode
the step size must be a multiple of the smallest possible step size
the number of triggers exceeds the allowed limit
379,Continuous Sweep = On for 81602A, 81606A, 81607A, 81608A, 81609A
->
"triggerNum > max"
