Abstract

Un circuito probador de cable de LAN se describe teniendo componentes de extremo de circuito de medida y componentes de extremo de cortocircuito. Los componentes de extremo del circuito de medida son convencionales e incluyen un multiplexor que tiene un generador de corriente y circuiteria de deteccion de voltaje electricamente acoplada al mismo. El multiplexor tambien tiene una pluralidad de pares de conductores electricos asociados incluidos en el cable bajo prueba acoplados al mismo. Los componentes de extremo de cortocircuito incluyen otro multiplexor que tiene los extremos opuestos de los conductores electricos acoplados al mismo, y ademas tienen un amplificador de voltaje diferencial y dos amplificadores diferenciales de salida de corriente electricamente acoplados al mismo. Los componentes de extremo de cortocircuito proporcionan un corto activo que elimina el efecto en la resistencia que se puede atribuir a los multiplexores de circuito integrado de semiconductor.
