Measuring
Time
Between
Two
Points
When
measuring time between two points, measurements can be determined
from
SWEEP
TIME/DIV
and horizontal distance.
1.
Display
the waveform by adjusting each control. Set all the
VARIABLE
controls to the
CAL
position.
2.
Work
the <\ •
POSITION
control to bring one point to be measured in
line
with
a
vertical
graduation
line.
Then
work
the ^
POSITION
control to
bring
the other point to be measured in
line
with
the horizontal scale in the
middle
of the
CRT
display screen.
3.
Measure the horizontal distance between the two points.
Multiply
this value
by
the
SWEEP
TIME/DIV
setting value. If the X
10MAG
function has been
activated,
multiply the value by 1/10.
Horizontal
distance
Line
up the point on the center
horizontal
scale using the
A
POSITION
control.
Time
between two points = horizontal distance (div) X
SWEEP
TIME/DIV
setting value
When
using the X 10
MAG
function:
Time
between two points = horizontal distance (div) X
SWEEP
TIME/DIV
setting value X 1/10
EXAMPLE:
In
the case of Figure 13, the horizontal distance between the two points is 5.4 div.
If
the
SEEEP
TIME/DIV
setting value is 0.2 ms/div, the time between the two
points may be calculated as
follows.
Time
between two points = 5.4div X 0.2ms/div = 1.08ms
If
the X
10MAG
function is in use:
Time
between two points = 5.4div X 0.2ms/div X 1/10 = 0.108ms
=
108 a s
