Peak Excursion Sets the minimum amplitude variation of
signals that the marker identifies as a peak.
If a value of 10 dB is selected, the marker
moves only to peaks that rise and fall more
than 10 dB above the peak threshold value.
When the peak excursion is 6 dB of higher,
NOTE
Two signal peaks, which are so close together that the amplitude drop
between them is less than the peak-excursion value, are not
recognized as two peaks. A signal peak is recognized only if it has a
peak excursion drop above the noise floor, on both sides of the signal.
the marker- peak do not recognize signals less
than peak- excursion value above the noise
floor. To correct this, when measuring signals
near the noise floor, reduce the excursion
value. To prevent the marker from identifying
noise as signals, reduce the noise floor
variance less than the peak- excursion value
by reducing the video bandwidth or by using
video averaging.

Peak
Threshold
Sets the minimum amplitude that the marker
can identify as
a peak. For example, if set to
–90 dBm, the marker moves only to peaks
that rise and fall more than the peak
excursion above –90 dBm.
