Take a
look at
the
oscilloscope
display.
Notice
the grid
markings
on the
screen -
these
markings
create
the
graticule.
Each
vertical
and
horizontal
line
constitutes
a
major
division.
The
graticule
is
usually
laid out
in an
8-by-10
division
pattern.
Labeling
on the
oscilloscope
controls
(such as
volts/div
and
sec/div)
always
refers
to major
divisions.
The tick
marks on
the
center
horizontal
and
vertical
graticule
lines
(see
Figure
1) are
called
minor
divisions.
Many
oscilloscopes
display
on the
screen
how many
volts
each
vertical
division
represents
and how
many
seconds
each
horizontal
division
represents.
Many
oscilloscopes
also
have 0%,
10%,
90%, and
100%
markings
on the
graticule
(see
below
Figure)
to help
make
rise
time
measurements
