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 wave-
length 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.
