Abstract

UN GENERADOR DE SEÑAL DE DIENTE DE SIERRA (18) DE UN CIRCUITO DE DEFLEXION VERTICAL ACOPLADO DE CORRIENTE CONTINUA DIRECTA ES SENSIBLE, DURANTE EL MODO DE SERVICIO OPERATIVO, A UNA SEÑAL PRIMERA (VCENT) A UN NIVEL DE CORRIENTE CONTINUA QUE ES INDICATIVO DE CENTRADO VERTICAL. DURANTE EL MODO DE SERVICIO OPERATIVO, LA GENERACION DE SEÑAL DE DIENTE DE SIERRA (VRAMP) SE INVALIDA Y, EN SU LUGAR, EL GENERADOR GENERA UNA SEÑAL DE CORRIENTE CONTINUA ACOPLADA POR MEDIO DE UN AMPLIFICADOR DE DEFLEXION VERTICAL (11A,FIG.1C) A UN DEVANADO DE DEFLEXION VERTICAL (LY) EN UNA MANERA PARA POSICIONAR UN HAZ DE ELECTRONES EN EL CENTRO VERTICAL DE LA PANTALLA DE VISUALIZACION.
