CALCulate3 Subsystem
SNR:REFerence[:WAVelength]
Sets the wavelength used for the noise measurement reference in the signal-to-noise
calculation.
:CALCulate3:SNR: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
Preset State: unaffected by
*RST State: 1550.0 nm in a vacuum.
SCPI Compliance: instrument specific
After entering this value, use the SNR:AUTO command to configure the instrument
to use this value in subsequent signal-to-noise calculations. The number entered is
converted internally to the corresponding frequency.
The default units for the <real> parameter are meters.
