Programming Commands
CALCulate3 Subsystem
SNR:REFerence:WNUMber
Sets the wave number used for the noise measurement reference in the signal-
to-noise calculation.
Syntax
:CALCulate3:SNR:REFerence:WNUMber{?| {<real> | MINimum | MAXimum}}
<real>
is a wave number value that is within the following limits:
Constant
Description
MINimum 6060 cm
-1
(1650 nm)
MAXimum 14286 cm
-1
(700 nm)

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
wave number entered is converted internally to the corresponding frequency.
The default units for the
<real>
parameter are m
–1
.
SNR[:STATe]
Turns the signal-to-noise calculation on and off.
