Abstract

Un analizador de redes incluye una unidad principal y una unidad remota físicamente separada. En al menos una configuración, la unidad principal genera y transmite señales de prueba a través de un dispositivo bajo prueba a la unidad remota. Los circuitos de referencia de la unidad principal usan señales procedentes de un oscilador local y de un reloj de muestreo del ADC analógico-digital para producir datos de señal de referencia representativos de las señales de prueba transmitidas al dispositivo bajo prueba. El sistema de circuitos de recepción de la unidad remota produce datos de señal recibida representativos de las señales de prueba recibidas desde el dispositivo bajo prueba, con el uso de las mismas señales procedentes del oscilador local y del reloj de muestreo del ADC que usa el sistema de circuitos de referencia para producir los datos de señal de referencia. La comparación de los datos de señal recibida con los datos de señal de referencia indica parámetros del dispositivo bajo prueba, que incluyen la atenuación y el desplazamiento de fase en las señales de prueba que provoca el dispositivo bajo prueba.
