2.5.5 Limits
Limit lines can be defined to compare the data to your defined limits and indicate a pass or
fail condition.
Limits accesses menus that allow you to create, modify, and change the
properties of limit lines. There are two limit lines in the instrument.

Remote Command:

<x-axis>, <

<connect

: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.
Frequencies are always in Hz. Time is always in seconds. No unit is
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.
