You take
time
measurements
using
the
horizontal
scale of
the
oscilloscope.
Time
measurements
include
measuring
the
period,
pulse
width,
and
timing
of
pulses.
Frequency
is the
reciprocal
of the
period,
so once
you know
the
period,
the
frequency
is one
divided
by the
period.
Like
voltage
measurements,
time
measurements
are more
accurate
when you
adjust
the
portion
of the
signal
to be
measured
to cover
a large
area of
the
screen.
Taking
time
measurement
along
the
center
horizontal
graticule
line,
having
smaller
divisions,
makes
for the
best
time
measurements.
