D E L A Y T I M E M U L T Control
Adjusts the start time of the B s w e e p to s o m e delay
time after the start of the A sweep.
T h e delay time may be set to values between 0.2 and
10 times the setting of the A S W E E P T I M E / D I V c o n -
trol.

| T R A C E S E P
Adjusts vertical separation between A s w e e p and B
s w e e p (control has effect only in the A L T of HORIZ
D I S P L A Y ) .
Clockwise rotation .increases separation; B s w e e p
moves down with respect to A s w e e p up to 4 divi-
sions.
In this case, H O L D O F F control has no effect. T h i s
control is effective w h e n the HORIZ D I S P L A Y s w i t c h
is selected to A L T . Even w h e n the HORIZ D I S P L A Y
s w i t c h is selected to DUAL, this control is effective
with the vertical M O D E s w i t c h set to C H 1 , C H 2 or
A D D position.

Rotation adjusts holdoff (trigger inhibit period beyond
s w e e p duration). Counterclockwise rotation increases
holdoff period from NORM to max more than five
times before the B E N D S A position.
In the B E N D S A position (fully counterclockwise), the
A s w e e p is reset at the end of the B sweep.
therefore intensity of B s w e e p increases. B E N D S A
mode is applicable to the A L T , A - I N T - B and B DLY'D
modes of HORIZ D I S P L A Y .

S O U R C E S w i t c h
Six-position lever s w i t c h ; selects triggering source for
the A s w e e p , with following positions;
V. MODE:
T h e trigger source for A s w e e p is deter-
mined by vertical M O D E selection.
C H 1 :
Channel 1 signal is used as a trigger
source.
C H 2 :
Channel 2 signal is used a s a trigger
source.

channel 2 signal is the trigger source. (If
C H 2 INV engaged, the difference be-
c o m e s the trigger source.)
D U A L :
For A L T mode the signals for
Q U A D :
through C H 4 alternate a s the trigger
( A L T )
source. For the C H O P mode the chop-
(CHOP)
ping signal becomes the trigger source.
N O T E :
1. W h e n the vertical M O D E s w i t c h is
selected to C H O P position, the dis-
play cannot be observed w i t h the in-
put since the chopping signal be-
c o m e s the trigger source.
2. Synchronization is impossible w h e n
input signals are not applied to all
channels with the vertical M O D E
s w i t c h set to D U A L or Q U A D posi-
tion.
C H 1 :
A s w e e p is triggered by channel 1 signal re-
gardless of vertical M O D E selection.
C H 2 :
A s w e e p is triggered by channel 2 signal re-
gardless of vertical M O D E selection.
1 / 1 :
A s w e e p is triggered by channel 3 signal.
1 / 1 0 :
A s w e e p is triggered by channel 3 signal at-
tenuated to 1 / 1 0 .
LINE:
A s w e e p is triggered by line voltage.

C O U P L I N G S w i t c h
Five-position lever s w i t c h ; selects coupling for
trigger signal.
A C :
Trigger is ac coupled. Blocks dc component
of input signal; most commonly used posi-
tion.
L F R E J :
Trigger is coupled through a high-pass filter
to eliminate low frequency components for
stable triggering of high frequency signals.
H F R E J :
Trigger is coupled through a l o w - p a s s filter
to eliminate
high
for a stable triggering of low frequency s i g -
nals.
DC:
Trigger is dc coupled for s y n c w h i c h includes
the effects of dc components. For channel 3
and channel 4, the vertical position adjust-
ment has no effect on the trigger point.
V I D E O : For synchronization of video signals. T h e
position of the A S W E E P T I M E / D I V control
determines whether F R A M E or LINE is to be
synchronized.
0.1 m s result in F R A M E while those between
5 0 fis and 2 0 n s result in LINE sync.
