摘要：A radio paging test system for testing the sensitivity of a radio receiver which receives a group of transmitted signals from a transmitter. Each transmitted signal in the group of transmitted signals is detected ad then compared to a reference signal to determine the degree of similarity between the reference signal and the detected signal. Each detected signal is classified either as a missed page, a non-page or a decoded page depending on the degree of similarity between the detected signal and the reference signal. In one mode of operation the classification of each detected signal is indicated by a classification signal which may be utilized to activate an alert such as a transducer or LED. Each classification signal may be directed to a computer input for analysis. In another mode of operation the classification signals are further analyzed to determine if the pager sensitivity is above, below or at a predetermined level. An alert indicating the pager sensitivity is then generated.
