5. :CALCulate:LLINe<n>:CONTrol:INTerpolate:TYPE
Syntax :CALCulate:LLINe<n>:CONTrol:INTerpolate:TYPE
LOGarithmic|LINear
:CALCulate:LLINe<n>:CONTrol:INTerpolate:TYPE?
Function Sets the type of frequency interpolation.
The query returns “LOG” or “LIN”.
Explanations

<n> is 1 (lower limit line) or 2 (upper limit line).

In Log mode, both frequency and amplitude use Log for an
interpolation operation.

In Line mode, the frequency uses Lin and the amplitude uses
Log for an interpolation operation.
Default LINear

6. :CALCulate:LLINe<n>:STATe
Syntax :CALCulate:LLINe<n>:STATe OFF|ON|0|1
:CALCulate:LLINe<n>:STATe?
Function Turns on or off the upper/lower limit line.
The query returns “0” or “1”.
Explanations <n> is 1 (lower limit line) or 2 (upper limit line).
Default
OFF|0

7. :CALCulate:LLINe<n>:DATA
Syntax :CALCulate:LLINe<n>:DATA
<x-axis>,<ampl>,<connected>{,<x-axis>,<ampl>,<connected>}
:CALCulate:LLINe<n>:DATA?
Function Creates a limit line, take the case of three points:
:CALC:LLIN2:DATA 50,100,0,100,150,1,200,200,1
The query returns:
50,100.000000,0,100,150.000000,1,200,200.000000,1
Explanations

<n>: denotes the limit line to be edited, which can be “1”
(lower limit line) or “2” (upper limit line).

<x-axis>: denotes the frequency (in Hz) or time (in us) of
selected point.
