Margin
Defines a margin for the limit line. The default setting is 0 dB (i.e. no margin).
For details on margins see chapter 7.5.2, "Basics on Limit Lines", on page 524.
Remote command:
CALCulate:LIMit<k>:LOWer:MARGin on page 980
CALCulate:LIMit<k>:UPPer:MARGin on page 983
X-Axis
Describes the horizontal axis on which the data points of the limit line are defined.
Includes the following settings:
●
Domain:
– "Hz": for frequency domain
– "s": for time domain
●
Scaling mode: absolute or relative (Hz/s/%) values
For relative values, the frequencies are referred to the currently set center fre-
quency. In the zero span mode, the left boundary of the diagram is used as the ref-
erence.
●
Scaling: linear or logarithmic

CALCulate:LIMit<k>:UPPer:MODE on page 983
CALCulate:LIMit<k>:CONTrol:DOMain on page 978
Y-Axis
Describes the vertical axis on which the data points of the limit line are defined.
Includes the following settings:
●
Level unit
●
Scaling mode: absolute or relative (dB/%) values
Relative limit values refer to the reference level.
●
Limit type: upper or lower limit; values must stay above the lower limit and below
the upper limit to pass the limit check
Remote command:

CALCulate:LIMit<k>:UPPer:SPACing on page 984
Data points
Each limit line is defined by a minimum of 2 and a maximum of 200 data points. Each
data point is defined by its position (x-axis) and value (y-value). Data points must be
defined in ascending order. The same position can have two different values.
