CALCulate2 Subsystem

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

1270 nm

 

MAXimum

wavelength limit stop value

Attribute

Non- sequential command

Summary

Preset State: 1270 nm

 

*RST State: 1270 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 Agilent 86120C to wait for non-sequential commands” on

 

 

page 3-12for more information.
