CALCulate3 Subsystem
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
Description
MINimum 700.0 nm
MAXimum 1650.0 nm
Attribute
Summary
Preset
State: unaffected by
*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 frequency.
The default units for the
<real>
parameter are meters.
