For the example, when the horizontal distance between
t w o signals is 4 . 4 divisions. T h e S W E E P T I M E / D I V is
0 . 2 (ms/div). (See Fig. 2 1 )
Substituting the given value:
Time = 4 . 4 (div) x 0 . 2 (ms/div) = 0 . 8 8 ms

(2) Cursor measurement
1 . In the same w a y as the ordinary measurement, adjust
waveforms to be measured to an easy-to-observe posi-
tion.
2 . Set the cursor mode to A T .
3 . Adjust the A R E F cursor to the left point time dif-
ference between which is to be measured, and the A cur-
sor to the right.
4 . Measured value is displayed in the upper right part on
the screen posterior to A T .

7. PULSE WIDTH MEASUREMENTS
(1) Ordinary measurement
Pulse width can be measured as follows:
Procedure:
1 . Apply the pulse signal to the INPUT jack. Set the vertical
MODE to the channel to be used.
2. Use the V O L T S / D I V , V A R I A B L E and • POSITION to ad-
just the waveform such that the pulse is easily observed
and such that the center pulse width coincides with the
center horizontal line on the C R T screen.
3 . Set the S W E E P V A R I A B L E switch to C A L . Measure the
horizontal distance between the intersections of the
pulse waveform and C R T center horizontal line in divi-
sions, and multiply the measured distance by the value
indicated by S W E E P T I M E / D I V . If the " x 1 0
mode is activated, also multiply the value by 1/10.
Using the formula:
Pulse width = Horizontal distance (div) x (SWEEP TIME/DIV
setting)x " x M A G 10"value"
Adjust to the vertical scale

[EXAMPLE]
For the example, the distance (width) at the center horizon-
tal line is 4 . 6 divisions and the S W E E P TIME/DIV is
0 . 2 (ms/div.) (See Fig. 2 3 )
Substituting the given value:
Pulse width = 4 . 6 (div) x 0 . 2 (ms/div) = 0 . 9 2 ms
