Note
When
using
the
limit-test
function,
it
is
important
to
keep
track
of
which
detector
output
is
being
tested
against
which
limit
line
.
The
peak
detector
is
the
default
detector
,
however
,
most
commercial
limit
lines
indicate
acceptable
quasi-peak
or
average
detector
output
levels
.
When
viewing
the
peak
detector
output,
it
is
possible
to
trigger
a
limit
failure
when
testing
against
a
quasi-peak
limit
line
.
This
type
of
failure
only
indicates
the
need
to
remeasure
the
signal
with
the
quasi-peak
detector
.
It
is
quite
possible
for
the
peak
value
of
an
impulsive
signal
to
exceed
a
quasi-peak
limit,
while
the
quasi-peak
value
of
that
same
signal
remains
below
the
limit.
