How the Instrument Works
Basics of Sequential Sampling
Figure
13-4. Acquisition
with
record
length
=
2250.
Sequential
sampling
cannot
sample
the
input signal
until
a
trigger
event
is
received.
Consequently
,
the
actual
triggered edge
cannot
be
viewed
without
using
a
delay
line
.
Use
of
a
delay
line
compensates
for
internal
delays in
the
triggering
and
sampling
circuits
within
the
instrument.
It
can
be
observed
from
Figure
13-2
that
there
is
an
amount
of
time after
the
scope
has
been
triggered
during
which
it
is
not
yet
ready to
accept
another trigger
,
even
if
a
valid
trigger
event
occurs
.
This
is
known
as
trigger
setup-and-hold time
,
which
determines
the
maximum
rate
at
which
a
signal
can be acquired.
