摘要
An isolation detecting device includes a signal receiver for receiving an attenuated RF signal and transmitting at least part of the attenuated RF signal to a power sensor for conversion into a voltage signal, an A/D converter for converting the voltage signal into a numerical value, and a processing module for determining a received transmission power of the attenuated RF signal with reference to the numerical value and at least one reference set, which contains a transmission power and a numerical value associated with a test RF signal, and for further determining an isolation value by subtracting the received transmission power from a preset transmission power at which an original RF signal resulting into the attenuated RF signal is transmitted.
