:CALCulate3:DELTa:WPOWer[:STATe] Turns the delta wavelength and power measurement mode on
and off.
I
:CALCulate3:DRIFt:DIFFerence[:STATe] Sets the drift calculation to subtract the minimum values
measured from the maximum values measured.
I
:CALCulate3:DRIFt:MAXimum[:STATe] Sets the drift calculation to return the maximum power
(frequency) values measured.
I
:CALCulate3:DRIFt:MINimum[:STATe] Sets the drift calculation to return the minimum power
(frequency) values measured.
I
:CALCulate3:DRIFt:PRESet Turns off all the drift states for DIFFerence, MAXimum,
MINimum, and REFerence.
I
:CALCulate3:DRIFt:REFerence:RESet Places the current list of signals into the reference list. I
:CALCulate3:DRIFt:REFerence[:STATe] Turns the drift state on and off so that CALC3:DATA? will return
the reference signal list.
I
:CALCulate3:DRIFt[:STATe] Turns the drift measurement calculation on and off. I
:CALCulate3:POINts? Queries the number of points in the data set. I
CALCulate3:PRESet Turns off any CALCulate3 calculation that is on. I
:CALCulate3:SNR:AUTO Selects the internal or externally entered frequency value for the
noise measurement reference in the SNR calculation.
I
:CALCulate3:SNR:REFerence:FREQuency Sets the frequency used for the noise measurement reference in
the SNR calculation.
I
:CALCulate3:SNR:REFerence[:WAVelength] Sets the wavelength used for the noise measurement reference
in the SNR calculation.
I
:CALCulate3:SNR:REFerence:WNUMber Sets the wave number used for the noise measurement
reference in the SNR calculation.
I
:CALCulate3:SNR[:STATe] Turns the SNR calculation on and off. I
DISPlay Subsystem
:DISPlay:MARKer:MAXimum Sets the marker to the signal with the largest power. I
:DISPlay:MARKer:MAXimum:LEFT Moves marker to signal with the next lower wavelength or
frequency.
I
:DISPlay:MARKer:MAXimum:NEXT Moves the marker to the signal with the closest power level just
below the power level of the signal at the current marker
position.
I
:DISPlay:MARKer:MAXimum:PREVious Moves the marker to the signal with the closest power level just
above the power level of the signal at the current marker
position.
I
:DISPlay:MARKer:MAXimum:RIGHt Moves marker to the next higher wavelength or frequency. I
:DISPlay[:WINDow]:GRAPhics:STATe Turns the instrument display of the power bars on and off. S
