NOTE
When using the
:CALCulate:LLINe:CONTrol:DOMain TIME
command, do
not use the
:CALCulate:LLINe[1]|2:CONTrol:INTerpolate:TYPE
LOGarithmic command. An error will result because this combination attempts
to determine the log of zero, which is undefined.

Remarks: For TIME, the limit line segments are placed on the spectrum
analyzer display with respect to the sweep time setting of the
analyzer, with 0 at the left edge of the display.
For FREQuency, segments are placed according to the
frequency that is specified for each segment.

:CALCulate:LLINe[1]|2:CONTrol:INTerpolate:TYPE
LOGarithmic|LINear
:CALCulate:LLINe[1]|2:CONTrol:INTerpolate:TYPE?
Selects the type of interpolation done for the frequency values of the designated
limit line when comparing to measured data. This only applies in the frequency
domain. This function does not work in zero span (when the analyzer is in the time
domain).
Remarks: Once this function is defined, the selected type is persistent.
Persistent means that it retains the setting previously selected,
even through a power cycle.

:CALCulate:LLINe[1]|2:DATA?
Defines limit line values, and destroys all existing data. Up to 200 points may be
defined for each limit. No units are allowed.
• <x-axis> – can be frequency or time values as specified by
: CALCulate:LLINe:CONTrol:DOMain . Frequencies are always in Hz.
