PULSE WIDTH
MEASUREMENTS
Perform
the
following
procedure
to
measure
the pulse
width of
a displayed
waveform:
1.
Install the
time-base
unit in
a mainframe
horizontal
compartment (either
A or
B
horizontal
in
a four-
compartment
mainframe).
2.
Connect the
signal
to be measured
to
the
vertical
unit
input.
3.
Set the
mainframe
horizontal-
and
vertical-mode
switches
to display
the time
base
and
vertical
unit.
(Check
that the
time base
VARIABLE
(CAL IN)
control
is
pushed
in and
the HOLD
OFF
control
is in
the
MIN
position.)
4. Set the
TRIGGERING
switches
and
LEVEL
control
for
a
stable display
(see General
Operating
information
for
selecting
proper triggering).
5.
Set
the
vertical
deflection
factor
and
position
control
for
about
a
5-division
pulse
vertically
centered
on the
graticule.
6.
Set the TIME/DIV
switch
and
POSITION
control
for
1
complete
pulse
displayed
within
the
center
8
graticule
divisions
as shown in Figure
2-7.
7. Measure
the horizontal
distance
in
divisions
between
the
50%
amplitude points
of the
displayed
pulse
(see Fig.
2-7.).
8. Multiply the
horizontal
distance
measured
in
step 7
by
the TIME/DIV
switch
setting.
(Divide
the
answer
by 10 if
sweep magnification
is
used.)

Measuring
the rise
time and
fall
time
of
a displayed
waveform.
Example:
Assume
that the
horizontal
distance
between
the
50% amplitude
points
is
3 divisions,
and
the
TIME/DIV
switch setting
is
.1
fjs
(see Fig. 2-6).

formula:
