5 - 4 T i m e i n t e r v a l measurement mode
In the time interval measurement mode, the
t r a n s i t i o n time f r o m a specified signal edge on
C H A N N E L A to a specified signal edge on
C H A N N E L B is measured.
T o gain an accurate measurement result ( t i m e
i n t e r v a l ) , input of t w o s i g n a l s w i t h stable cycle
time to the C H A N N E L A and C H A N N E L B
t e r m i n a l s is required. F o r example, use the t w o
d i g i t a l s i g n a l s f r o m the same clock generator.
If the same signal is input to the t w o j u c k s ,
the duty cycle can be measured. F o r more

Considerations'.
Measurement Procedures
(1) Input target signals to channels A and B ( ©
and © ) .
(2) Select the t i m e interval measurement mode
( T I / A - + B ) w i t h F U N C s w i t c h © .
Symbol A - » B indicates t h a t the t r a n s i t i o n
time f r o m channel A to channel B is
measured.
(3) Specify desired signal edges of the t w o
signals on channels A and B by using
C H A N N E L A and C H A N N E L B - S L O P E
switches © and © . If these switches are
pressed (
)
, the negative-going edge w i l l be
selected. If left open
(ML),
the positive-going
edge w i l l be selected.
Note : If the t r a n s i t i o n t i m e between the t w o
same edges of the same signal needs to
be measured, use the period measurement
mode.
F o r more d e t a i l s , refer to chapter 6
' 6 - 4 . Measuring Considerations'.
(4) Press C H A N N E L A T R I G L E V E L control ® ,
and the adjust w i l l be set to the P R E S E T
position. In t h i s case, the trigger level of
the s i g n a l s on the t w o channels is set to the
center point ( a l m o s t average l e v e l ) .
(5) Select a desired measurement unit w i t h display
