Peak-to-Peak Voltage Measurements—
AC
To make
peak-to-peak voltage
measurements,
use the
following
procedure:
1
.
Set
the Input Coupling on the vertical plug-in
unit to
GND and connect the signal to the input connector.
2.
Set
the Input Coupling to AC and set the Volts/Div
switch
to
display about 5 or
6
vertical divisions of
the
waveform. Check that the Variable Volts/Div control (red
knob)
is in the Cal
position.
3. Adjust
the time-base
triggering controls for
a stable
display
and set
the Seconds/Div
switch
to display several
cycles
of
the waveform.
4. Turn the
vertical Position control so the lower
portion of
the
waveform coincides
with
one
of
the graticule
lines below the center
horizontal line,
and the top
of
the
Position
to center
vertical
line

is
in the
viewing area. Move the display
with the
horizontal Position
control so one
of
the
upper peaks is
aligned with the
center vertical reference line (see
Fig.
2-2).
5.
Measure the vertical deflection from peak to peak
(divisions)
.
NOTE
This technique
may
also be
used to
make measure-
ments
between
two points on
the waveform
,
rather
than
peak to
peak.
6.
Multiply the distance (in divisions)
measured
in step
5
by
the Volts/Div switch setting. Also
include the attenua-
tion factor of the probe, if applicable.
EXAMPLE:
Assume
a
peak-to-peak vertical deflection of
4.6
divisions and
a
Volts/Div switch
setting of 5 V.

NOTE
If an
attenuator probe not having
the capability to
change
the scale factor readout (Volts/Div)
is used,
multiply the right side of
the above
equation by the
attenuation factor.
