After
plugging
in the
oscilloscope,
take a
look at
the
front
panel.
It is
divided
into
three
main
sections
labeled
Vertical,
Horizontal,
and
Trigger.
Your
oscilloscope
may have
other
sections,
depending
on the
model
and type
(analog
or
digital).
Notice
the
input
connectors
on your
oscilloscope.
This is
where
you
attach
probes.
Most
oscilloscopes
have at
least
two
input
channels
and each
channel
can
display
a
waveform
on the
screen.
Multiple
channels
are
handy
for
comparing
waveforms.

of an
Oscilloscope
Some
oscilloscopes
have an
AUTOSET
or
PRESET
button
that
sets up
the
controls
in one
step to
accommodate
a
signal.
If your
oscilloscope
does not
have
this
feature,
it is
helpful
to set
the
controls
to
standard
positions
before
taking
measurements.
Standard
positions
include
the
following:
Set
the
oscilloscope
to
display
channel
1
Set
the
volts/division
scale
to a
mid-range
position
Turn
off
the
variable
volts/division
Turn
off
all
magnification
settings
Set
the
channel
1
input
coupling
to
DC
Set
the
trigger
mode
to
auto
Set
the
trigger
source
to
channel
1
Turn
trigger
holdoff
to
minimum
or
off
Set
the
intensity
control
to a
nominal
viewing
level
Adjust
the
focus
control
for
a
sharp
display
These
are
general
instructions
for
setting
up your
oscilloscope.
If you
are not
sure how
to do
any of
these
steps,
refer to
the
manual
that
came
with
your
oscilloscope.
The
Controls
section
describes
the
controls
in more
detail.
