Sets
an
amplitude
parameter
(for
example
,
0

dB) that
denes the
start and
stop points
for
a
bandwidth
search.
The
bandwidth search
feature analyzes
a bandpass
or band
reject
trace
and
calculates
the
center
point,
bandwidth,
and
Q
(quality
factor) for
the
specied
bandwidth.
Bandwidth
units
are
in
the
units of
the current
format. When
the
tracking
1marker
or
the xed
1marker is
on, the
bandwidth value
specied
is
the
dierence
from
the
1marker
