APPLICATION
4 - C H A I M N E L A P P L I C A T I O N
The sensitivities of C H 1 to C H 4 are calibrated and each
channel has 1 0 0 M H z b a n d w i d t h . The trigger signals of
C H 3 and C H 4 can be o b t a i n e d f r o m each preamplifiers.
This unit can be used not only for external synchronization
b u t also for c h e c k i n g 4 - C h a n n e l at a t i m e .
A p p l i c a t i o n
1. Checking logic signal t i m i n g
2. M o n i t o r i n g video signal
3. M e a s u r i n g audio signal gain and phase characteristics
The details of the logic signal t i m i n g c h e c k i n g are described

H. D I S P L A Y : A
To o b t a i n stable synchronization, synchronize w i t h the
longest period channel (in this case, C H 3 ) .
In t h e above application, w h e n the H. D I S P L A Y control is
set t o A L T , the m a i n and delay s w e e p w a v e f o r m s are dis-
played on the CRT at a t i m e . The p o r t i o n in w h i c h the i n t e n -
sity is m o d u l a t e d is enlarged t o enable easy checking.

CH 1 and C H 3 : 1 0 0 Hz signal input
C H 2 and C H 4 : 1 M H z signal input
W i t h this m e t h o d , w h e n the s w e e p ratio is set t o 1 0 , 0 0 0
t i m e s , t h e intensity does not change and different period
w a v e f o r m can be synchronized.
W h e n H. D I S P L A Y control is set to D U A L and t w o or four
w a v e f o r m s are displayed, t h e C H 1 and C H 3 w a v e f o r m s are
displayed in A s w e e p m o d e and C H 2 and C H 4 w a v e f o r m s
are displayed in B s w e e p m o d e . Therefore, adjust the A and
B. TRIG S O U R C E control accordingly.
