Abstract

ANALIZADOR LOGICO QUE ES APROPIADO PARA MEDIR SEÑALES LOGICAS, QUE SE EMITEN A PARTIR DE VARIOS OBJETOS A EXAMINAR Y NO SON CORRELATIVOS. ESTAN PREVISTOS MODULOS (24,34) DE REDACCION DE SEÑALES QUE SE ACOPLA EN UNA PIEZA A ENSAYAR (21,31) COORDINADA Y CONTIENE UN SELECCIONADOR (51) DE TIEMPO PARA LA DEDUCCION DE UNAS SEÑALES DE TIEMPO EXTERNAS E INTERNAS, UN REGISTRADOR (52) DE EXPLORACION, UN DETECTOR (53) DE EXPLORACION, UN DISPOSITIVO DE SINCRONIZACION (54), UN DETECTOR (57) DE SUCESOS, UN CONTROLADOR/ACUMULADOR (56) Y UN ACUMULADOR DE DATOS (55). LA DISPOSICION DE SINCRONIZACION (54) CONTIEN UN REGISTRADOR DE SINCRONIZACION PARA ACUMULAR DATOS DE SEÑALES QUE SE LEEN EN EL REGISTRADOR DE EXPLORACION EN LA PUESTA EN MARCHA SOBRE LA SEÑAL DE EXPLORACION Y DE TIEMPO Y SE EXPLORAN CON LA SEÑAL DE TIEMPO INTERNA Y UNA DISPOSICION LOGICA QUE CEDE EN LA PUESTA EN MARCHA SOBRE LA SEÑAL DE TIEMPO INTERNA Y LA SEÑAL DE EXPLORACION UN IMPULSO DE MARCA Y EXPLORACION QUE MARCA EL TIEMPO DE UNA EXPLORACION.
