Pit Search
For marker search functions, a signal pit is defined as having a fall and then a
rise in the displayed 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.

Pit Search
Places a marker on the lowest amplitude trace point which meets the pit
excursion criteria. If no marker is on, Marker #1 will be used for the pit search.

Precision Sweep Mode
Precision mode offers the most accurate sweep setting to use if you are con-
cerned about wavelength and amplitude accuracy for final filter test applica-
tions. However, the increased accuracy also increases the sweep time.
