SNR:REFerence[:WAVelength]
Sets the wavelength used for the noise measurement reference in the
signal- to- noise calculation.
Syntax
:CALCulate3:SNR:REFerence[:WAVelength]{?| {<real> | MINimum | MAXimum}}
<real> is a wavelength value that is within the following limits:
Constant
MINimum
MAXimum
Attribute
Preset State: unaffected by
Summary
*RST State: 1550.0 nm in a vacuum
SCPI Compliance: instrument specific
Description
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 fre-
quency.
The default units for the <real> parameter are meters.
