Display
systems
vary
between
analog
and
digital
oscilloscopes.
Common
controls
include:
An
intensity
control
to
adjust
the
brightness
of
the
waveform.
As
you
increase
the
sweep
speed
of
an
analog
oscilloscope,
you
need
to
increase
the
intensity
level.
A
focus
control
to
adjust
the
sharpness
of
the
waveform.
Digital
oscilloscopes
may
not
have
a
focus
control.
A
trace
rotation
control
to
align
the
waveform
trace
with
the
screen's
horizontal
axis.
The
position
of
your
oscilloscope
in
the
earth's
magnetic
field
affects
waveform
alignment.
Digital
oscilloscopes
may
not
have
a
trace
rotation
control.
Other
display
controls
may
let
you
adjust
the
intensity
of
the
graticule
lights
and
turn
on
or
off
any
on-screen
information
(such
as
menus).
