CALCulate3 Subsystem
DELTa:REFerence[:WAVelength]
Selects the reference laser line for DELTa calculations.
Syntax
:CALCulate3:DELTa:REFerence[:WAVelength]{?| {<real> | MINimum | MAXimum}}
<real> is a wavelength value that is within the following limits:
Constant
MINimum
MAXimum
Attribute Preset State: 1270 nm (236.0571 THz)
Summary *RST State: 1270 nm (236.0571 THz) laser line
SCPI Compliance: instrument specific
Description The reference will be the laser line at the wavelength closest to the
wavelength entered. Subsequent measurements will use the wavelength
closest to the reference wavelength used for the previous measurement.
The query returns the current wavelength of the reference laser line.
The default units for the <real> parameter are meters.
4-52
