Abstract
"MéTODO E APARELHO PARA TESTE EM TEMPO REAL DE SISTEMAS DE TRANSMISSãO DE ANTENA DE DTV EM DOMìNIO DE TEMPO SOB POTêNCIA TOTAL". A invenção refere-se a um aparelho em tempo real para testar um sistema de transmissão de antena de DTV, em que o sistema de transmissão de antena de DTV transmite um sinal original de um transmissor de DTV para uma antena de transmissão de DTV, que inclui uma sonda, em que a sonda está conectada em série com o sistema de transmissão de antena de DTV, e detecta os sinais que atravessam o sistema de transmissão de antena de DTV. Um detector de erro do aparelho de teste compara o sinal recebido com o sinal original para identificar a magnitude e a localização do erro.
