Bool
OFF|ON|0|1
OFF|0
Remarks
OFF|0: disables the coupling function. That is, "Fixed" is selected under Y to Ref, and the amplitude of the
current limit line editing point is not be affected by the reference level.
ON|1: enables the coupling function. That is, "Relative" is selected under Y to Ref, and the amplitude of
the current editing point is the difference between the amplitude of the point and that of the current
reference level. At this time, if the reference level changes, then the position of the current editing point
changes along with the reference level.
Return Format
The query returns 0 or 1.
Example
The following command disables the coupling functions between the selected limit line data points and the
reference level.
:CALCulate:LLINe2:AMPLitude:CMODe:RELative OFF or :CALCulate:LLINe2:AMPLitude:CMODe:RELative 0
The following query returns 0.
:CALCulate:LLINe2:AMPLitude:CMODe:RELative?
:CALCulate:LLINe<n>:BUILd
Syntax
:CALCulate:LLINe<n>:BUILd TRACE1|TRACE2|TRACE3
