1. Anordning för automatisk regiering av släckbias för ett bildrör, vars intensitet kan kontrolleras med hjälp av dess styr-galler- och katodelektroder och till en elektronkanon av vilket genom kopplingsorgan matas en videosignal som innehäller periodis-ka bild- och släckintervaller, och vilken omfattar en referens-spänningskrets för att mata referensspänning till katoden av bild-röret under en mätintervall, vilken är delvis samtidig med släck-intervallen, en hjälppulskrets för matning av en hjälppuls under mätintervallen, till styrgallerelektroden av bildröret för att alstra en konektionssignal, och en mätkrets för att definiera skill-naden mellan katodströmmen som flyter under hjälppulsintervallen och under restportionen av mätintervallen, respektive, vilka ka-todströmmar avviker med ett fel som skall korrigeras, och en reg-lersignalkrets för att alstra en reglersignal frän korrektions-signalen för regiering av bildrörbias till ett släckvärde som skall hällas konstant, kännetecknad därav, att videosignalen matas till katodelektroden Ct.ex. 16a) av bildröret (15) och hjälp-pulsen (Vg i fig. 7) matas till styrgallerelektroden av bildröret biaserande i framriktningen, och att mätkretsen (22) är en spän-ningskänslig krets som definierar katodströmpulsen ( AV i fig. 13) som alstrats i beroende av hjälppulsen som differens i förhällande tili katodspänningen under restportionen av mätintervallen och att reglersignalkretsen (24) alstrar den nämnda reglersignalen för att reglera den nämnda differensen tili ett minimivärde.
2. Anordning enligt patentkravet 1, kännetecknad därav, att mätkretsen (22) omfattar en spänningsdelarkrets (65,66) som är inkopplad mellan den nämnda katodelektroden (t.ex. 16a) och en driftpotential och att den nämnda hjälppulsen är en spännings-puls .
3. Anordning enligt patentkravet 2, kännetecknad därav, att den nämnda spänningsdelarkretsen (65,66) omfattar en resistanskrets.
4. Anordning enligt patentkraven 1 och 2,känneteck-n a d därav, att den nämnda hjälpsignalen ästadkommes oberoende av den nämnda videosignalen som är matad tili katodelektroden (t.ex. 16a) i en förstärkt form.
