CALCulate2:WLIMit[:STATe]?
Queries the wavelength limits state.
:CALCulate2:WLIMit[:STATe] {ON | OFF}
Turns wavelength limits on or off.
:CALCulate2:WLIMit:{ :STARt | STOP }?
Queries wavelength limit STARt or STOP
wavelength.
:CALCulate2:WLIMit:STARt {1267…1686}
Sets the starting wavelength for the wavelength limit
range.
:CALCulate2:WLIMit:STOP {1267…1686}
Sets the stopping wavelength for the wavelength
limit range.
:CALCulate2:FPAV?
Queries the state of the Fabry-Perot Averaging
mode (ON or OFF)
:CALCulate2:FPAV
Sets the instrument in the FPAV mode. FETCh,
READ, and MEAS queries return the power-
weighted average wavelength or total power.
:CALCulate2:AVERage[:STATe]?
Queries the spectral averaging state.
:CALCulate2:AVERage[:STATe] {ON | OFF}
Turns spectral averaging on or off.
:CALCulate2:AVERage:COUNt?
Queries the number of spectra to be averaged.
:CALCulate2:AVERage:COUNt
Sets the number of spectra to be averaged.
:CALCulate2:AVG:CLEar
Resets and restarts the spectral averaging, if
spectral averaging is turned on.
:CALCulate2:SNR:AUTO?
Queries the state of the OSNR location and
bandwidth automatic calculation.
:CALCulate2:SNR:AUTO{ON | OFF}
Turns the automatic calculation of OSNR location
and bandwidth on or off.
:CALCulate2:SNR:WAVelength?
Queries the user wavelength used for SNR
calculations.
:CALCulate2:SNR:WAVelength
Sets the user wavelength location used for SNR
calculations, if SNR:AUTO is OFF.
:CALCulate2:SNR:BANDwidth?
Queries the user bandwidth used for SNR
calculations.
:CALCulate2:SNR:BANDwidth
Sets the user bandwidth used for SNR calculations,
if SNR:AUTO is OFF.
DISPlay Subsystem
These commands change the state of the
instrument's front panel.
:DISPlay:DIALog?
Queries the current display screen on the front of the
instrument.
:DISPlay:DIALog {MAIN | LISt }
Selects the current display screen on the front of the
instrument.
:DISPlay:UNITs:POWer?
Queries the power units used for display.
:DISPlay:UNITs:POWer {DBM | MW}
Selects the power units used for display.
:DISPlay:UNITs:WAVelength?
Queries the wavelength units used for display.
:DISPlay:UNITs:WAVelength {NM | THZ |
WNUMber }
Selects the wavelength units used for display.
SENSe Subsystem
These commands are used to control factors that
affect the way in which the measurements are taken.
:SENSe:AVERage?
Queries the wavelength and power averaging state.
