If
a delta
marker or
xed marker
is
on,
it
is
used
as
the
reference
point from
which
the
bandwidth
amplitude
is
measured.
For
example
,
if
marker
1
is
the
delta
marker
and
is
set
at the
passband
maximum,
and
the
width
value
is
set
to
0
3dB
,
the
bandwidth
search
nds
the
bandwidth
cuto
points
3
dB below
the
maximum
and
calculates
the
3
dB
bandwidth
and
Q.
If
marker
2
(the
dedicated
bandwidth
center
point
marker)
is
the
delta
reference
marker
,
the
search
nds
the
points
3
dB
down
from
the
center
.
If
no
delta
reference
marker
is
set,
the
bandwidth
values
are
absolute
values
.

WINDOW:
MAXIMUM
(Option

sets
the
pulse
width
to
the
widest
value
allowed.
This
minimizes
the
sidelobes
and
provides
the
greatest
dynamic
range

the most
useful
because
it
