[ Limit Line Data ]
:CALCulate:LLINe1|2|3|4:DATA
Function description:
This command is used to set/query the value of the limit line.
Setting format:
:CALCulate:LLINe1|2|3|4:DATA <freq>,<ampl>,<connect>{,<freq>,<ampl>,<connect>}
Query format:
:CALCulate:LLINe1|2|3|4:DATA?
Parameter description:
Limit line values are composed of 3 data:
<freq> Frequency: The frequency unit that can be input is Hz, KHz, MHz, GHz or k, M, G. The
default unit is Hz.
<ampl> Amplitude value: There is no unit for the amplitude value, and the unit of the current
measurement parameter is used as the default value;
<connect> Connection status: The connection status among the points of the limit line:
1: Indicates that the current point is connected with the previous point with a straight line;
0: Indicates that the current point is not continuous and is not connected with the previous point.
Return value:
Without units:
<freq>,<ampl>,<connect>{,<freq>,<ampl>,<connect>}
Example:
:CALCulate:LLINe2:DATA 5GHz,9dB,1,6G,6.4,1
:CALCulate:LLINe2:DATA?

Description:
The limit line itself has no unit, which is defined according to the unit of the graph
during application. If the unit of the graph changes, the system will automatically
replace it with a new unit without changing the unit of the limit line.
[ Number of Limit Line Data ]
:CALCulate:LLINe1|2|3|4:COUNt?
Function description:
This command is used to query the number of the limit line data.
