Abstract
Abstract A device for testing two way radios, particularly Citizen Band mobile transceivers, includes a console with a front panel having meters for displaying rf power, percent modulation, rf voltage, transceiver output frequency, DC voltage and AC voltage, a channel selector for testing various channel frequencies and a signal level adjust knob permitting receiver sensitivity testing, a test sequence selector for controlling operation of the device in self test, transmit test and receive test modes, a coaxial connector for receiving an antenna connector of a transceiver to be tested, and AC and DC power hookup sockets. Within the console are a transmit test circuit for receiving the output of a transceiver to be tested via the antenna connector and the coaxial connector including a frequency counter providing a frequency signal corresponding to the frequency of the transceiver output for display by the frequency meter and a signal processing circuit for selectively supplying signals representative of the transceiver output power and percent modulation to the appropriate meters, and a receive test circuit for supplying a test signal to the coaxial connector for supply to the transceiver to be tested via the antenna connector such that the test signal can be heard on a speaker of the transceiver.
