A limit line can be defined as either an upper or lower limit.
IEC/IEEE-bus command: --
(defined by key words :UPPer or :LOWer)
Margin - Setting a margin.
The margin is defined as the signal-level distance to the limit line . When the
limit line is defined as an upper limit, the margin means that the level is below
the limit line. When the limit line is defined as a lower limit, the margin means
that the level is above the limit line. The default setting is 0 dB (i.e. no
margin).
