[EXAMPLE]
For the example, when the horizontal distance between
two signals is 4.4 divisions. The SWEEP TIME/DIV is
0.2 (ms/div). (See Fig. 40)
Substituting the given value:
Time = 4.4 (div) x 0.2 (ms/div) = 0.88 ms

(2) Cursor measurement
1. In the same way as the ordinary measurement, adjust
waveforms to be measured to an easy-to-observe posi-
tion.
2. Set the cursor mode t o A 1.
3. Adjust the A REF 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 switch to the channel to be used.
2. Use the VOLTS/DIV, VARIABLE 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 CRT screen.
3. Set the SWEEP VARIABLE switch to CAL. Measure the
horizontal distance between the intersections of the
pulse waveform and CRT center horizontal line in divi-
sions, and multiply the measured distance by the value
indicated by SWEEP TIME/DIV. If the " x 10MAG"
mode is being used, also multiply the product by 1/10.
Using the formula:
Pulse width = Horizontal distance (div) x (SWEEP TIME/DIV
setting) x " xMAG IC'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 SWEEP TIME/DIV is 0.2
(ms/div.). (See Fig. 42)
Substituting the given value:
Pulse width = 4.6 (div) x 0.2 (ms/div) = 0.92 ms
