RIGOL
Queries whether the amplitudes of the mask points are coupled to the reference level of the instrument.
Parameter
Name
Type
——
Bool
Remarks
OFF|0: disables the coupling function. That is, when "Fixed" is selected under Y Axis Type, the amplitude
of the current mask point will not be affected by the reference level.
ON|1: enables the coupling function. That is, when "Relative" is selected under Y Axis Type, the amplitude
of the current mask point is the difference between the point and the current reference level.
If you modify the state of this parameter after the mask has been set, the amplitude of the mask should
make corresponding changes based on the state of the parameter, so as to keep the relations between the
mask and the reference level of the instrument unchanged.
When on, the amplitude of the mask point is expressed as an offset from the reference level.
This command is only valid when you select FMT to be the trigger source.
Return Format
The query returns 1 or 0.
Example
The following command enables the coupling relationship between the amplitudes of the mask points and
the instrument's reference level.
:TRIGger:SEQuence:FMT:MASK:RELative:AMPLitude ON
or :TRIGger:SEQuence:FMT:MASK:RELative:AMPLitude 1
The following query returns 1.
:TRIGger:SEQuence:FMT:MASK:RELative:AMPLitude?
:TRIGger[:SEQuence]:FMT:MASK:RELative:FREQuency
Syntax
:TRIGger[:SEQuence]:FMT:MASK:RELative:FREQuency OFF|ON|0|1
:TRIGger[:SEQuence]:FMT:MASK:RELative:FREQuency?
Description
Sets whether the frequencies of the mask points are coupled to the center frequency of the instrument.
Queries whether the frequencies of the mask points are coupled to the center frequency of the instrument.

Remarks
OFF|0: disables the coupling function. That is, when "Fixed" is selected under X Axis Type, the frequency
of the current mask point will not be affected by the center frequency.
ON|1: enables the coupling function. That is, when "Relative" is selected under X Axis Type, the frequency
of the current mask point is the difference between the point and the current center frequency.
If you modify the state of this parameter after the mask has been set, the frequency of the mask should
make corresponding changes based on the state of the parameter, so as to keep the relations between the
mask and the center frequency of the instrument unchanged.
When on, the frequencies of the mask points are expressed as an offset from the center frequency. At this
time, the frequencies of the mask points can be negative values.
This command is only valid when you select FMT to be the trigger source.
