The "Level" and "Frequency" or "Time" settings define the position and value of the ref-
erence point.
Alternatively, a Peak Search can be performed to set the maximum value of the
selected trace as the reference point.
If "Automatic Peak Search" is activated, a peak search is started automatically after
each sweep and the result is used as the reference point.
