Abstract

"MéTODO E ARRANJO EM TESTE DE EXTREMIDADE úNICA DE UMA LINHA DE SINAL". A invenção se relaciona a teste de extremidade única de uma malha (2, 3) com a ajuda de um transceptor (1), em que uma impedância de entrada (Z~ entrada~ (<sym>) da malha é gerada. O transceptor (1) tem uma parte digital (41), um codificador/decodificador (42) e uma parte analógica (43) e está conectado à malha. Com a ajuda de um sinal de banda larga transmitido e um refletido (V~ entrada~, V~ saída~), uma função de tansferência de eco H~ eco~ (<sym>) V~ saída~ (f)/V~ entrada~ (<sym>) é gerada, que também pode ser expressa como fórmula (i). Aqui, Z~ hO~ (<sym>), Z~ hib~ (<sym>) e H~ <sym>~ (<sym>) são valores de modelo para o transceptor (1). Em um processo de calibração, um transceptor de teste, com o mesmo tipo de hardware como o transceptor (1), é conectado a impedâncias conhecidas, substituindo a malha (2, 3). H~ eco~(<sym>)=V~ saída~(<sym>)/V~ entrada~(<sym>) é gerada para as impedâncias conhecidas e os valores de modelo são gerados e são armazenados em uma memória (1 1) no transceptor (1). Os valores de modelo armazenados são então usados quando a impedância de entrada (Z~ entrada~(<sym>)) para a malha (2, 3) é gerada depois que uma medição do sinal de banda larga (V~ entrada~,V~ saída~) é executada.
