Increasing Measurement Accuracy
Measuring time intervals
In this section, we discuss measuring a pulse width to show the principles of
time-interval measurement. The time interval you want to measure might be
a
setup
time
,
a
propagation delay
,or
a rise
time.
However
,
all
time-interval
measurements
made
with
instruments
are
similar.
In
all
cases
you
measure
the
time
between two
events,
where
an
event
is
dened
as
a
voltage
transition
of
a
specied
polarity
through
a
specied
level.
When
measuring
the
width
of
a
pulse
,
these
two
events
are
the
leading
edge
and
the
trailing
edge
.
The
concepts
developed
here
can
be
applied
to
any
other
time-interval
measurement.
F
or
two-channel
measurements
,
you
must
take
care
to
deskew
the
two
channels
.
Refer
to
\Channel-to-channel
measurements", later
in
this
chapter
,
for
more
information.
