(f) Chromaticity (x,y) Offset (Correction Function)
Set and Query Chromaticity (x,y) Offset Function
Syntax
Command
:SCALe:XY:OFFSet
<1/0/ON/OFF >
Query
:SCALe:XY:OFFSet?
Response
<1/0(NR1)>
Description
Command
Sets the chromaticity (x,y) offset function.
When the chromaticity (x,y) offset function is enabled, the value set
by
:SCALe:XY:OFFSet:DATA:#
is added to the measured value of the
chromaticity (x,y) of the RGB mixed light.
When the command is accepted, the measured value is cleared and the
instrument enters the non-measurement state.
Query
Queries the currently set chromaticity (x,y) offset function.
Example
:SCAL:XY:OFFS ON
:SCAL:XY:OFFS?
1
Note
• As a result of addition of the offset value, the chromaticity may become a non-existent
value.
Set and Query Offset Value of Chromaticity (x,y) (
# is X or Y
)
Syntax
Command
:SCALe:XY:OFFSet:DATA:#
<Offset value(NRf)>
Query
:SCALe:XY:OFFSet:DATA:#?
Response
<Offset value(NR3)>
<Offset value> = -1.0000E+00 to 1.0000E+00
Description
Command
Sets the offset value of the chromaticity (x,y).
The offset value is added to only the measured value of the chromaticity
(x,y) of the RGB mixed light.
:SCALe:XY:GAIN:DATA:X
→ Offset value of chromaticity (x)
:SCALe:XY:GAIN:DATA:Y
→ Offset value of chromaticity (y)
When the command is accepted, the measured value is cleared and the
instrument enters the non-measurement state.
Query
Queries the currently set offset value of the chromaticity (x,y).
:SCALe:XY:GAIN:DATA:X?
→ Offset value of chromaticity (x)
:SCALe:XY:GAIN:DATA:Y?
→ Offset value of chromaticity (y)
Example
:SCAL:XY:OFFS:DATA:X -0.5
:SCAL:XY:OFFS:DATA:X?
-5.0000E-01
:SCAL:XY:OFFS:DATA:Y 0.1
:SCAL:XY:OFFS:DATA:Y?
1.0000E-01
Note
• # is X or Y.
• As a result of addition of the offset value, the chromaticity may become a non-existent
value.
• The tristimulus values XYZ of the RGB mixed light are recalculated using the chromaticity
(x,y) of the RGB mixed light on which this offset value has been reflected.
