A C : T h e B s w e e p trigger signal is applied to the
trigger circuit by A C coupling. DC compo-
nent is eliminated.
N O I S E REJ: T h e B s w e e p trigger signal with reduced
trigger sensitivity is applied to the trigger cir-
cuit. Therefore, trigger signal with noises
can cause triggering stably.
HF REJ: T h e B s w e e p trigger signal is applied to the
trigger circuit via a low-pass filter. Since
high-frequency components are attenuated,
low-frequency
stably.
D C : T h e B s w e e p trigger signal is applied to the
trigger circuit by DC coupling, enabling trig-
gering including DC component.
T V LINE: Triggered by the horizontal synchronizing
signal of the video signals.
@ B TRIGGERING L E V E L (B LEVEL) Control
Trigger level control of B s w e e p . S e t s a s w e e p start
point on a slope of the trigger signal w a v e f o r m . Trig-
ger level adjustment is unnecessary if the B COUPLING
s w i t c h (§) is set to T V LINE, or T R I G G E R I N G M O D E
s w i t c h e s @ is set to F I X .
© B TRIGGERING S O U R C E (B SOURCE) Selector Switch
and LEDs
Selects a trigger source of B s w e e p . Every press of the
• s w i t c h a d v a n c e s a selected LED from left to right in
sequence. Next to A F T . D , C H 1 is selected. (A select-
ed L E D a d v a n c e s at the interval of approx. 0 . 5 second
by keeping pressing the s w i t c h . )
C H 1 : B s w e e p is triggered by channel-1 vertical axis
input signal.

signals can be triggered

Fig. 5
C H 2 : B s w e e p is triggered by channel-2 vertical axis
input signal.
C H 3 : B s w e e p is triggered by channel-3 vertical axis
input signal.
C H 4 : B s w e e p is triggered by channel-4 vertical axis
input signal.
A F T . D : T h e B Start After Delay s w e e p mode is select-
ed. B s w e e p starts after a delay time set with
the A S W E E P T I M E / D I V © and D E L A Y POSI-
TION control (§) has passed.
N O T E : If any of C H 1 to C H 4 is selected, the
triggered delay mode is selected: B
s w e e p is triggered by the first trigger
pulse after a delay time set with the DE-
L A Y
mark ( ? ) is displayed posterior to DE-
L A Y on the C R T .
© B TRIGGERING SLOPE (B SLOPE) Switch
Selects triggering polarity of the B s w e e p . Pressing the
s w i t c h turns on the L E D and selects triggering at the
trailing edge of input w a v e f o r m . Another press of the
s w i t c h turns off the L E D and selects triggering at the
leading edge of input w a v e f o r m .
N O T E : If the T V F R A M E or LINE of the A COUPLING
s w i t c h © is selected, the B S L O P E is set to the
same condition a s the A S L O P E . If the A,
C O U P L I N G s w i t c h @ is set to another one, the
previous condition is restored.
