TRIG COUPLING
Select the coupling method used for the trigger signal.
W h e n NORM is selected w i t h s w i t c h @ , either A C coupling ( J I _ A C ) or D C coupling
( _M _ DC) can be selected w i t h s w i t c h (§).
A C : Trigger signal is A C coupled to the s y n c circuit. Blocks D C component of input
signal. Most commonly used position for w a v e f o r m observation.
DC: Trigger signal is D C coupled to the s y n c circuit. S w e e p is trigger by signal in-
cluding D C component.
W h e n
T V
(
J L
) is selected w i t h s w i t c h
(22),
vertical s y n c (_•_) or horizontal s y n c ( J * . )
is selected by s w i t c h
(23).
V: S w e e p is triggered by vertical s y n c pulses of video signal.
H: S w e e p is triggered by horizontal s y n c pulses of video signal.
® S W E E P VARIABLE
Provides fine adjustment of s w e e p time; continuous adjustment is possible b e t w e e n
steps selected by S W E E P T I M E / D I V © . S w e e p time is calibrated by in the extreme clock-
w i s e ( C A L ) position.
(25) S W E E P TIME/DIV
S w e e p time coarse selector. S e l e c t s s w e e p times between 0 . 2 /ts/div and 1 s/div in
21 s t e p s . Indicated v a l u e s are calibrated w h e n S W E E P V A R I A B L E ® control is set to
C A L position (fully c l o c k w i s e ) . Oscilloscope is set to X - Y operating mode w h e n this
knob is rotated to fully c o u n t e r c l o c k w i s e ( X - Y ) position. In X - Y operation, s w e e p i n g
stops and the source selected by T R I G or X © becomes the X axis amplifier and the
source selected by V or Y M O D E ® becomes the Y a x i s amplifier.
© % POSITION/PULL x 5 MAG
Rotation adjusts the horizontal position of the trace on the display. Pulling this knob
increases the s w e e p time five t i m e s . T h e S W E E P T I M E / D I V value is 1 / 5 of the indicat-
ed value at this time.
