Measurement Operations & Settings Signal Generation – The SOURce Subsystem
136 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
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 con-
figured 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
example: sour0:wav:swe:chec? → "triggerNum > max"
affects: All tunable laser modules except Agilent 81649A and Agilent 81689A/B
