CALCulate<Chn>:LIMit:LOWer:SHIFt <LimShift>
CALCulate<Chn>:LIMit:UPPer:SHIFt <LimShift>
These commands shift all lower and upper limit line segments assigned to the active
trace in vertical direction. Both commands shift all limit lines; they have the same func-
tionality. See also

Example:
Usage:
Manual operation:
CALCulate:LIMit:POINts:LOWer? <TraceName>
CALCulate:LIMit:POINts:UPPer? <TraceName>
Reads the effective lower/upper limit points from a limit line test for an arbitrary (not
necessarily the active) trace, referenced by its name <TraceName>.
"Effective" means:
●
Only points within the sweep range and only active limit checks are considered.
●
Disabled limit line segments
OFF) are ignored.
●
Both linear/logarithmic interpolation and limit line formulae are supported.
●
If there are overlapping limit line segments, only the tighter limit is reported.

String parameter containing the trace name
Limit points, either in ASCII or block data format, depending on
the current FORMat[:DATA].
One limit point = one value (y-axis) per sweep point (x-axis).
"No limit point" is reported as Not a Number, which is the string
"-NAN(IND)" in ASCII and a float testing true for "isnan".
If there is no effective limit point, an empty response is returned.
