[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:LLOGging
[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:LLOGging<wsp>OFF|ON|0|1
Switches lambda logging on or off. Lambda logging is a feature that records the exact
wavelength of a tunable laser module when a trigger is generated during a continuous
sweep. You can read this data using the [:SOURce[n]][:CHANnel[m]]:READout:DATA?
command.
The following settings are the prerequisites for Lambda Logging:
• Set "[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:MODE" on page 112 to
CONTinuous.
• Set ":TRIGger[n][:CHANnel[m]]:OUTPut" on page 121 to STFinished (step
finished).
• Set "[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:CYCLes" on page 109
to 1.
• Set "[:SOURce[n]][:CHANnel[m]]:AM:STATe[l]" on page 96 to OFF.
If any of the above prerequisites are not met, then when the sweep is started the
status "Sweep parameters inconsistent" will be returned and Lambda Logging will
automatically be turned off.
Lambda logging is disabled at the end of a sweep.
