Abstract

L'invention concerne l'étalonnage de l'axe de base de temps dans un appareil d'affichage. Elle se caractérise en ce que des signaux 1 dérivés d'un signal de référence 10 déclenchent le balayage 5 tandis que des signaux 2 retardés 12 par incréments par rapport aux premiers signaux servent à l'affichage 7 de fronts d'ondes que l'on aligne sur les lignes verticales du graticule lors de l'ajustement. Application : oscilloscopes.
