The screenshot above shows an example curve of the calculated MPX power
[MPX Power 60 s] (orange). For convenient analysis and set up the graph allows to display a second
MPX curve [MPX Power User] (green) with a user defined integration time. This is especially useful to
see why the MPX Limiter starts working although the MPX power has not reached threshold.
The purple curve shows the gain reduction action of the MPX Limiter. The center white line represents
the selected MPX Limiter reference.
