Quality control unit for radiotelephone equipment - has transmission and receiving sections and master oscillator connected to terminals to set functional mode

摘要

A quality control unit for radiotelephone communication is used to check transmission and reception of equipment. The equipment uses frequency distributed channels of given bandwidth. The unit has transmission section and a receiving section. The transmission section has an aerial common with the receiving section. It has a terminal for a signal defining the functional mode of either transmission-receiving or simple receiving. A set of terminals is used for establishing the channel to be checked, its network and its bandwidth. Another set of terminals is connected to the signal code receiver and a set of terminals receives a signal giving the identification code of the subscriber. A module is used to set the master oscillator according to the signals received.
