(d) Centroid Wavelength Offset (Correction Function)
Set and Query Centroid Wavelength Offset Function
Syntax
Command
:SCALe:WAVelength:OFFSet
<1/0/ON/OFF >
Query
:SCALe:WAVelength:OFFSet?
Response
<1/0(NR1)>
Description
Command
Sets the centroid wavelength offset function.
When the centroid wavelength offset function is enabled, the value set
by
:SCALe:WAVelength:OFFSet:DATA:#
is added to the measured value of
the centroid wavelength.
When the command is accepted, the measured value is cleared and the
instrument enters the non-measurement state.
Query
Queries the currently set centroid wavelength offset function.
Example
:SCAL:WAV:OFFS ON
:SCAL:WAV:OFFS?
1
Note
When the centroid wavelength input mode is enabled, no offset is added regardless of this
offset function setting.
Set and Query Offset Value of Centroid Wavelength (
# is R, G, or B
)
Syntax
Command
:SCALe:WAVelength:OFFSet:DATA:#
<Offset value(NRf)>
Query
:SCALe:WAVelength:OFFSet:DATA:#?
Response
<Offset value(NR3)>
<Offset value> = -2.00 to 2.00 [nm]
Description
Command
Sets the offset value of the centroid wavelength.
When the command is accepted, the measured value is cleared and the
instrument enters the non-measurement state.
:SCALe:WAVelength:OFFSet:DATA:R
→ Offset value of red centroid
wavelength
:SCALe:WAVelength:OFFSet:DATA:G
→ Offset value of green centroid
wavelength
:SCALe:WAVelength:OFFSet:DATA:B
→ Offset value of blue centroid
wavelength
Query
Queries the currently set offset value of the centroid wavelength.
:SCALe:WAVelength:OFFSet:DATA:R?
→ Offset value of red centroid
wavelength
:SCALe:WAVelength:OFFSet:DATA:G?
→ Offset value of green centroid
wavelength
:SCALe:WAVelength:OFFSet:DATA:B?
→ Offset value of blue centroid
wavelength
Example
:SCAL:WAV:OFFS:DATA:R 0.1
:SCAL:WAV:OFFS:DATA:R?
1.0000E-01
:SCAL:WAV:OFFS:DATA:G -1.0
:SCAL:WAV:OFFS:DATA:G?
-1.0000E+00
Note
• # is R, G, or B.
• When the centroid wavelength input mode is enabled, no offset is added regardless of
this offset function setting.
