摘要：In the trigger arrangement (1), which is particularly suitable for use inoscilloscopes comprising, for example, a cathode-ray tube as display device, a triggeroutput signal (10) is layed from a trigger input signal (6 ) after the trigger arrangement(1) is released by a release signal (8). Use is made of a series-combination of threebistable elements (2,4,16). The trigger input signal (6) is applied in parallel to the bistableelements (2,4,16) and the trigger output signal (10) is obtained after the output of eachbistable element (2,4,16) has successively changed its state, a difference occurringbetween the switching levels of the successive bistable elements (2,4,16) when thetrigger input signal (6) is applied to the bistable elements (2,4,16) differential amplifiers -

assumed to be included in the bistable elements (2,4,16). The first two bistable elements(2,4) form an accurately defined release signal (17) for releasing the third bistableelement (16). The instant of release of the third bistable element(16) is therebyprevented from coinciding - up to very high frequencies - with the instant at which thetrigger input signal (6) can cause the output (23) of the third bistable element (16) tochange its state after release of the third bistable element (16). By means of anoscilloscope provided with such a trigger arrangement, \"jitter\"-free signals can bedisplayed up to very high frequencies.
