:TRIGger[:SEQuence]:FMT:MASK:RELative:FREQuency
Syntax
:TRIGger[:SEQuence]:FMT:MASK:RELative:FREQuency ON|OFF|1|0
: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.
Parameter
Name
Type
Range
Default
——
Bool
OFF|ON|0|1
OFF|0
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 in RTSA mode.
Return Format
The query returns 1 or 0.
Example
The following command enables the coupling relationship between the frequencies of the mask points and
the instrument's center frequency.
:TRIGger:SEQuence:FMT:MASK:RELative:FREQuency ON
or :TRIGger:SEQuence:FMT:MASK:RELative:FREQuency 1
The following query returns 1.
:TRIGger:SEQuence:FMT:MASK:RELative:FREQuency?
:TRIGger[:SEQuence]:FMT:MASK<n>:BUILd
Syntax
:TRIGger[:SEQuence]:FMT:MASK<n>:BUILd TRACE1|TRACE2|TRACE3|TRACE4|TRACE5|TRACE6
Description
Creates a mask from a trace.
Parameter
Name

Range
Default
<n>
Discrete
1|2

Remarks
When <n> is set to 1, it indicates that the upper mask is being edited; when it is set to 2, it indicates that
the lower mask is being edited.
