Remote Command:
:CALCulate:LLINe[1]|2:DATA
<x-axis>, <ampl>, <connected>{,<x-axis>,<ampl>,<connected>}
:CALCulate:LLINe[1]|2:DATA?
Defines the limit line values, and destroys all existing data. Up to 200 points may be
defined for each limit using the following parameters.
<x-axis> can be frequency or time values as specified by the following command:
:Calculate:LLINe:CONTrol:DOMain.
FrequenciesarealwaysinHz.Timeisalwaysinseconds.Nounitis
allowed in this parameter.
Range: -30 Gs to +30 Gs for time limits, -3 kHz to +350 GHz for frequency
limits.
<ampl> amplitude values are always in units of dBm. Up to two amplitude values
can be provided for each x-axis value, by repeating <x-axis> in the data
list. No unit is allowed in this parameter.
Range: -140 dBm to +100 dBm
<connected> connected values are either "0" or "1." A "1" means this point should be
connected to the previously defined point to define the limit line. A "0"
means that it is a point of discontinuity and is not connected to the
preceding point. The connected value is ignored for the first point.
:CALCulate:LLINe[1]|2:DATA:MERGe
<x-axis>, <ampl>, <connected>{,<x-axis>,<ampl>,<connected>}
Adds the points with the specified values to the current limit line, allowing you to merge
limit line data. Up to two amplitude values are allowed for each x value. If more than 200
points are entered to be merged, the first 200 points are merged into the existing limit,
then an error ‘too many DATA entries’ is reported.
Remote Command Notes: Up to 200 points total may be defined for each limit.
Example: CALC:LLIN1:DATA 1000000000, -20,0,200000000,-30,1
