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 Description
MINimum 700.0 nm
MAXimum 1650.0 nm
Attribute Summary Preset State: 700 nm (428.6 THz)
*RST State: 700 nm (428.6 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.
