CONTROLS AND INDICATORS
T R I G G E R S O U R C E C O N T R O L S
( 3 2 ) S O U R C E
This control selects t h e source for t h e A S w e e p Trigger.
V M O D E The trigger source for the A S w e e p is d e t e r m i -
ned by the Vertical M O D E setting.
CH1
CH1 signal is used as a trigger source
C H 2
C H 2 signal is used as a trigger source
A D D
The algebraic s u m of C H 1 and C H 2 signals
isured a signal source, (if C H 2 has been
inverted, t h e difference b e c o m e s t h e source.)
D U A L
Q U A D
(ALT)
(CHOP)
For A L T m o d e t h e signals for CH1 t h r o u g h
C H 4 alternate as the trigger source. For t h e
C H O P m o d e t h e c h o p p i n g signal b e c o m e s t h e
trigger source.

Triggering is impossible w h e n input signals are not
applied t o all channels w i t h the vertical axis m o d e
set t o

(34) L E V E L / S L O P E P U L L F I X
LEVEL
This outer control adjusts the level at w h i c h t h e A trigger
causes the A S w e e p be started.
SLOPE PULL FIX
This inner control adjusts t h e slope of the A trigger signal.
W h e n the control is pulled o u t t h e FIX m o d e is selected for
auto level a d j u s t m e n t , under w h i c h circumstances outer
TRIG LEVEL control no longer has any effect.
(35) T R I G ' D
This green LED lights w h e n the A trigger source signal c a u -
ses t h e initiation of a A S w e e p . It lights for X - Y operation
as well.
(36) C H 3 o r A E X T T R I G
Input connector for the C H 3 signal. It serves also as the
external A TRIG input connector. C H 3 signal m a y be o b -
served simultaneously w i t h CH 1, 2 a n d 4 signals w h e n t h e
Q U A D m o d e is selected.
W h e n t h e SOURCE control is set to either EXT (CH3) 1/1
or 1 / 1 0 , t h e trigger source is this input signal.
(37) S O U R C E
This control selects t h e B S w e e p trigger source.
C H 1 C H 1 signal is the trigger source for t h e B
S w e e p .
C H 2 C H 2 signal is the trigger source for t h e B
S w e e p .
1/1 C H 4 signal is the trigger source for t h e B
S w e e p .
1 / 1 0 The C H 4 signal, a t t e n u a t e d to 1 / 1 0 of its true
value is t h e trigger source for the B S w e e p .
( 3 3 ) C O U P L I N G
This control is used t o select the SYNC c o u p l i n g for t h e A
trigger.
A C S Y N C signal is A C coupled w i t h any DC c o m -
p o n e n t blocked.
LFREJ
SYNC signal is coupled t h r o u g h a high-pass fil-
ter t o e l i m i n a t e l o w frequency c o m p o n e n t s for
stable triggering of high frequency signals.
HFREJ
SYNC signal is c o u p l e d t h r o u g h a low-pass fil-
ter t o e l i m i n a t e high frequency c o m p o n e n t s for
a stable triggering of l o w frequency signals.
DC T h e S Y N C signal is DC coupled for S Y N C
w h i c h includes t h e effects of DC c o m p o n e n t s .

This control selects the S Y N C c o u p l i n g for t h e B trigger
group. Operation is similar t o that of the corresponding A

This outer control adjusts the level at w h i c h t h e B trigger
signal causes t h e start of the B S w e e p .
