Programming Commands
CALCulate2 Subsystem
WLIMit:STARt:WNUMber
Sets the starting wavenumber for the wavelength limit range.
Syntax
:CALCulate2:WLIMit:STARt:WNUMber {?|{<real> | MINimum | MAXimum}}
< real > is a wavenumber value that is within the following limits:
Constant Description
MINimum 6060 cm
-1
MAXimum wavelength limit stop value
Attribute Summary Non-sequential command
Preset State: 6.060606E5 m
-1
*RST State: 6.060606E5 m
-1
SCPI Compliance: instrument specific
Description This command sets the starting range for the wavelength limit. The default units for
the <
real > parameter value are m
-1
. The start wavenumber value must be less than or
equal to the stop wavenumber value or the start wavenumber will be clipped to the
stop wavenumber and a “Data out of range” error will be generated.
Non-sequential command
Always use an *OPC? query or a *WAI command to ensure that this command
has the time to complete before sending any more commands to the instrument.
Refer to “Always force the Keysight 86120B to wait for non-sequential com-
mands” on page 92
