APPLICATIONS
WIDTH
Puls«
width
The
WIDTH
measurement
is
calculated
between
the
MAIN
CURSORS,
it
is
necessary
to
set
the
main
cursors
on
the
wanted
trace,
using
the
CURSOR-SELECT
menu,
and
on
the
required
part
of
the
signal
using
the
CURSOR-CONTROL
menu
(see
also
Section
3.2.7).
By
activating
the
WIDTH
calculation
function
the
oscilloscope
will
automatically
measure
the
pulse
width
of
the
first
pulse
seen
from
the
left
cursor.
The
pulse
width
is
determined
on
the
half
peak-to-peak
amplitude
between
the
MAIN
CURSORS.
There
must
be
at
least
one
upgoing
edge
and
one
downgoing
edge
between
the
two
MAIN
CURSORS,
otherwise
an
error
message
is
given.
The
measuring
result
is
shown
in
the
right
corner
of
the
top
text
area.

RISE
Rise-time
The
RISE
(or
FALL)
measurement
Is
calculated
between
the
MAIN
CURSORS.
It
Is
necessary
to
set
the
main
cursors
on
the
wanted
trace,
using
the
CURSOR-SELECT
menu,
and
on
the
required
part
of
the
signal
using
the
CURSOR-CONTROL
menu.
By
activating
the
RISE
calculation
function,
the
oscilloscope
will
automatically
measure
the
rise-time
(or
the
fall-time,
if
the
first
signal
edge
is
negative-going)
of
the
first
signal
edge
seen
from
the
left
cursor.
The
rise-time
is
determined
on
the
nearest
sample
to
the
10
%
and
the
90
%
level
of
the
amplitude
between
the
MAIN
CURSORS.
The
measuring
result
is
shown
in
the
right
corner
of
the

text
area.
