Measure the
horizontal
distance
between the
time
measurement
points
.
Multiply
the
distance
measured
by
the setting
of
the
TIME/DIV
switch
.
If
sweep
magnification
is
used, divide
this
answer
by
10.
EXAMPLE: The
distance
between the
time
measure-
ment
points
is 8.3
divisions
(see Fig. 18) and the
TIME/DIV
switch
is
set to 2 ms
with
the
magnifier
off.
Using the
formula
:

Substitute

FREQUENCY
MEASUREMENTS
Time
Duration
measurements can be used to
determine
the
frequency
of
a recurrent signal as
follows
:
1.
Measure
one
cycle
of
the waveform
as
described
in
Time-Duration
Measurements.
2.
Take the
reciprocal
of
the
time
duration
to
deter-
mine
the
frequency
.
EXAMPLE:
The
frequency
of
the signal
shown
in
Fig.
18
,
which
has a time
duration
of
16.6
milliseconds
is:
