RELative
Limit line is defined by values relative to the reference level (dB).
*RST:
ABSolute
Example: CALC:LIM:LOW:MODE REL
Defines the y-axis of limit line 2 as relative scaled.
Manual operation: See "Edit Name" on page 186
CALCulate<n>:LIMit<k>:LOWer:OFFSet <Offset>
This command defines an offset for a complete lower limit line.
Compared to shifting the limit line, an offset does not actually change the limit line defi-
nition points.
Suffix:
<n>
.
irrelevant
<k> 1...8
Selects the limit line.
Parameters:
<Offset> Numeric value that defines the offset.
*RST:
0
Example: CALC:LIM2:LOW:OFFS 3dB
Shifts limit line 2 by 3 dB upwards.
Manual operation: See "Y Offset" on page 188
CALCulate<n>:LIMit<k>:LOWer:SHIFt <Distance>
This command moves a complete lower limit line vertically.
Compared to defining an offset, this command actually changes the limit line definition
points by the value you define.
Suffix:
<n>
.
irrelevant
<k> Selects the limit line.
Parameters:
<Distance> Numeric value that defines the distance of the shift.
The unit depends on
CALCulate<n>:LIMit<k>:UNIT
on page 676.
Example: CALC:LIM3:LOW:SHIF 20DB
Shifts all Y values of limit line 3 by 20 dB.
CALCulate<n>:LIMit<k>:LOWer:SPACing <InterpolType>
This command selects linear or logarithmic interpolation for the lower limit line.
