Abstract

PARA MEDIR RADIACION EMITIDA DESDE, O LA INFLUENCIA DE RADIACION SOBRE, UNA PLACA DE CIRCUITO IMPRESO INDIVIDUAL, LA CUAL EN USO ESTA NORMALMENTE DISPUESTA EN UNA RANURA EN PARALELO A OTRAS PLACAS DE CIRCUITOS IMPRESOS, ESTANDO CONECTADOS A UN PLANO POSTERIOR (3) COMUN, EL PLANO POSTERIOR (5) ESTA MODIFICADO DE TAL MODO QUE LA CONEXION (9) DE UNA PLACA (7) CONSIDERADA ESTARA LOCALIZADA SOBRE LA CARA OPUESTA DE DICHO PLANO POSTERIOR EN COMPARACION A LAS CONEXIONES (5) DE LAS OTRAS PLACAS (1). LA TOTALIDAD DEL EQUIPAMIENTO ESTA LOCALIZADO EN UN ALOJAMIENTO (11) APANTALLADO A EXCEPCION DEL CIRCUITO IMPRESO (7) CONSIDERADO. POR ELLO LA RADIACION DE LOS OTROS CIRCUITOS (1) IMPRESOS ESTARA APANTALLADA O ATENUADA Y SOLO LA RADIACION DEL CIRCUITO IMPRESO (7) CONSIDERADO CONTRIBUIRA AL CAMPO DE RADIACION ALREDEDOR DEL DISPOSITIVO. DEL MISMO MODO SOLO ESTE CIRCUITO IMPRESO (7) CONSIDERADO SERA SENSIBLE A RADIACIONES ELECTROMAGNETICAS QUE LLEGAN DEL EXTERIOR. LA FUENTE DE ENERGIA DEL DISPOSITIVO ESTAPREFERIBLEMENTE DOTADA POR EQUIPAMIENTO DE POTENCIA LOCALIZADO DENTRO DEL ALOJAMIENTO (11) PROTEGIDO, TAL COMO UNA BATERIA (15) O UNA UNIDAD (17) DE ADAPTACION DE ENERGIA DE TENSION CONTINUA.
