d) By setting the H O R I Z O N T A L MODE s w i t c h e s (§) toB, the A s w e e p waveform disappears, and theintensity-modulation part on the A s w e e p trace lineis magnified on the C R T .B s w e e pt r a c e lineN O T E : • Delayed s w e e p is impossible for 0.2 div.from the A s w e e p start point.• In the Start After Delay, increasing mag-nification will cause delay jitters. In sucha c a s e , use the triggered delay describedbelow.2. Triggered DelaySet the B S O U R C E s w i t c h e s © to any of C H 1 to C H 4 .( T R I G . C O U N T goes out.) The B s w e e p starts at the firsttrigger pulse after the delay time set with the D E L A Y PO-SITION @ has passed. Set the trigger level of the B sweepwith the B L E V E L control @ .Since the B s w e e p of triggered delayed s w e e p operationstarts at the first trigger signal after the delay time dis-played on the C R T , the displayed delay time serves asreference only. A " ? " is displayed posterior to D E L A Yon the C R T to indicate to that effect.T h o u g h t h e d e l a y t i m e , 200jis, i s s e t a t t h e p o i n t o f 2 d i v . , t h e t r i g g e r p o i n ta f t e r it i s a t t h e p o i n t o f 4 . 3 d i v . ; c o n s e q u e n t l y , t h e p a r t f r o m 4 . 3 d i v . i si n t e n s i t y - m o d u l a t e d (for m a g n i f i c a t i o n ) .Fig. 203 . TRIG COUNT SwitchThe T R I G COUNT switch is conveniently used for delayedsweep of signals w h o s e number of pulses is already-known s u c h as the video signal, digital signal, e t c .a) Select A of the H O R I Z O N T A L MODE s w i t c h e s (§),and set each s w i t c h and control knob for normalwaveform observation.b) Set the H O R I Z O N T A L MODE s w i t c h e s to A INT B,and select a channel to be observed ( C H 1 to C H 4 )with the B S O U R C E s w i t c h .c ) Activate the T R I G COUNT switch (LED lights up) andd e a c t i v a t e t h e c u r s o r m e a s u r e m e n t m o d e ;" C O U N T " is displayed in the upper right of the C R Tand a count value is displayed following it.d) On completion of the above setting, rotate the D E -L A Y POSITION control (28) to set the count value to1 . T h e n , rotate the B L E V E L @ to display intensity-modulation part on the C R T . If the A S L O P E and BS L O P E are set to the same value, the start point ofthe intensity modulation changes depending on set-ting of the A L E V E L (§) and B L E V E L @ , w h i c h shallbe set as follows:N O T E : The trigger counter regards the B s w e e p trig-ger point next to the A s w e e p trigger pointas " 0 " (not displayed) and the following Btrigger point as " 1 " .If the count value is set to 1 , the relationshipof these trigger points is as follows:iii) A S L O P E : - , B S L O P E : +iv) A S L O P E : - , B S L O P E : -Fig. 2 125Fig. 19i) A S L O P E : + , B S L O P E : -ii) A S L O P E : + , B S L O P E : -• B t r i g g e r l e v e l•A t r i g g e r l e v e lA t r i g g e r l e v e l• B t r i g g e r l e v e lB t r i g g e r l e v e lA t r i g g e r l e v e lA t r i g g e r l e v e lB t r i g g e r l e v e l- B t r i g g e r l e v e l-A t r i g g e r l e v e lA t r i g g e r l e v e l• B t r i g g e r l e v e lB t r i g g e r l e v e lA t r i g g e r l e v e l•A t r i g g e r l e v e l• B t r i g g e r l e v e l
