The higher the overlap factor, the more frames are used. This leads to more individual
results and improves detection of transient signal effects. However, it also extends the
duration of the calculation.

Max frame count
Restricts the maximum number of frames to be calculated. Due to the other parameter
settings, the required number of frames may become very high, thus slowing perform-
ance. By restricting the number of frames, you can avoid performance loss without
changing the other parameters.

Frame coverage
Due to the Max frame count restriction, the waveform may only be analyzed partially. The
"Frame coverage" indicates the percentage of the trace that was analyzed, i.e. which part
of the trace was included in the frame calculation.
