EXAMPLE:
The reference signal
amplitude
is 30
volts,
TIME DURATION
with
a VOLTS/DIV
switch setting
of 5
and the
VAR
VOLTSiDIV
control
adjusted to
provide
a
vertical
1. Obtain a
Normal Sweep
Display
(ensure
that
the
deflection
of exactly
four divisions. VAR TIME/DIV
control
is set to the calibrated
detent).
Substituting
these
values in the
vertical
conversion
factor
formula:
Vertical
Conversion
=
30
volts
=

For
the
unknown
signal,
the VOLTS/DlV
switch
setting
is 1,
and the
peak'to-peak
amplitude
spans
five
vertical
divisions.
The arbitrary
deflection
factor is then
determined
by substituting
values
in the
formula:
Arbitray
Deflection
=
1.5
X 1
volt/division
=
1.5
volts/division
Factor
The amplitude
of the
unknown signal
can
then
be
determined
by substituting
values
in the
unknown signal
amplitude
formula:
Amplitude =
1.5
volts/division X 5
divisions =
7.5
volts.

Set
the
TIME/DIV switch
for
