RIGOL Chapter 3 Command System for EMI Mode
3-22 RSA3000E Programming Guide
Example
The following command turns on Limit Line 2.
:CALCulate:LLINe2:DISPlay ON or :CALCulate:LLINe2:DISPlay 1
The following query returns 1.
:CALCulate:LLINe2:DISPlay?
:CALCulate:LLINe<n>:FAIL?
Syntax
:CALCulate:LLINe<n>:FAIL?
Description
Queries the measurement results of the selected limit line and its associated trace.
Parameter
Name
Type
Range
Default
<n>
Discrete
1|2|3|4|5|6
--
Remarks
If you enable the test for the displayed trace and its corresponding limit line, and each displayed trace has
its corresponding limit line enabled, then you can run the command to query whether the trace test passes.
Return Format
The query returns 0 (pass) or 1 (fail).
:CALCulate:LLINe<n>:FREQuency:CMODe:RELative
Syntax
:CALCulate:LLINe<n>:FREQuency:CMODe:RELative OFF|ON|0|1
:CALCulate:LLINe<n>:FREQuency:CMODe:RELative?
Description
Enables or disables the coupling functions between the selected limit line data points and the center
frequency.
Queries the setting state of the coupling functions between the selected limit line data points and the center
frequency.

Bool
OFF|ON|0|1
OFF|0
Remarks
OFF|0: disables the coupling function. That is, "Fixed" is selected under X to CF, and the frequency of the
current limit line editing point is not be affected by the midspan frequency.
ON|1: enables the coupling function. That is, "Relative" is selected under X to CF, and the frequency of the
current limit line editing point is the difference between the frequency of the point and that of the current
midspan frequency. At this time, if the midspan frequency changes, then the position of the current editing
point will move left and right with it.
