Pit Excursion (Marker Setup Panel)
Pit Excursion (Marker Setup Panel)
Sets the pit excursion value for the marker search routines.
The pit excursion value is used to determine whether or not a local minimum in the trace is to be
considered a pit.
For marker search functions, a signal pit is defined as having a fall and then a rise in the dis-
played response of at least the pit excursion value. Reducing the pit excursion to values less than
3 dB may cause the marker-pitting functions to identify noise spikes as pits. To reduce the noise
floor variance to a value less than the pit excursion rate, try changing the reference level at the
top of the graticule and increasing sensitivity.

marker is on, Marker #1 will be used for the pit search.
