from
the

Indicates
that
the

of
the

PEAK
EXCURSION
Denes
what
constitutes
a
peak
in
the
trace
.
The
value
species
the
amount
that
a
trace
must
increase
and
then
decrease
,
relative
to
the
surrounding
responses
or
noise
oors
in
order
to
be
dened
as
a
peak.
Upon
entering
a

,
complete
the
entry
with

PEAK
THRESHOLD
Sets
the
level
below
which
nothing
will
be
considered
a peak.
The
maximum
amplitude
of the
response
must
be
at
least
this
value
to
be
called
a
peak.
The
allowable
threshold values
range from
0
100
to
0
dB
.
The
default
value
is
0
70
dB
. Upon
entering a
value
,
complete
the
entry
with
4
x1
5
.
Any
part of
a peak
(as
dened
by
peak
excursion)
that
is
less
than
the
peak
threshold value
is also
used to
satisfy
the
peak
excursion
criteria.
F
or
example
,
when
the
peak
excursion
is
set
to
8
dB
,
a
peak
that
is
4
dB
above
and
4
dB
below
the
peak
threshold
will
be
considered
a
peak.
