[EXAMPLE]
In the example shown in Fig. 3 1 , the horizontal distance
between the t w o points is 5.4 divisions. If the S W E E P
T I M E / D I V is 0 . 2 ms/div, time to be determined is:
Time = 5.4 (div) x 0 . 2 (ms/div) = 1.08 ms

Cursor Measurement Procedures
1)
Display the w a v e f o r m to be measured in an easy-to-
see position according to the normal procedures above.
2)
Select the AT cursor mode with the C U R S O R S .
3)
Align the ziREF cursor to the left of the t w o points to
be measured, and the /icursor to the right.
4)
Measured value is displayed following AT in the upper
right of the C R T .

6 . TIME DIFFERENCE MEASUREMENT
(1) Normal Procedures
The following describes normal procedures for measuring
time difference between t w o signal synchronized to e a c h
other:
1)
Apply t w o signals to C H 1 and C H 2 input connectors.
Select A L T or C H O P of the V E R T I C A L MODE s w i t c h e s .
Generally, A L T is used for high-frequency signals, while
CHOP is used for low-frequency signals.
2)
Set each control for normal s w e e p display. Select the
faster of the t w o signals a s the A S O U R C E (reference
signal), and adjust
the
T I M E / D I V to obtain easy-to-see waveform display. S e t

graduation line with the
4)
Measure the horizontal distance between the t w o sig-
nals. Multiply this distance by the S W E E P T I M E / D I V
setting.
