WLIMit:STARt[:WAVelength]
Syntax
CALCulate2:WLIMit:STARt[:WAVelength] {?|{<real> | MINimum | MAXimum}}
< real > is a wavenumber value that is within the following limits:
Constant Description
MINimum 700.0 nm
MAXimum wavelength limit stop value
Attribute Summary Non-sequential command
Preset State: 700 nm
*RST State: 700 nm
SCPI Compliance: instrument specific
Description This command sets the starting range for the wavelength limit. The start wavelength
value must be less than or equal to the stop wavelength value or the start wavelength
will be clipped to the stop wavelength and a “Data out of range” error will be
generated. Setting the start wavelength is equivalent to setting the stop frequency/
wavenumber because of the inverse relationship of frequency to wavelength. The
default units for the <
real > parameter are meters.
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
for more information.
