PURPOSE: A device for testing a transceiver in a CDMA(Code Division Multiple Access) base station system is provided to quickly grasp the failure position of the transceiver by embodying a self diagnosis function in the transceiver. CONSTITUTION: A signal control unit(100) receives a control signal from an RFCA(RF Control Unit), and outputs two opposite switching control signals, respectively. A signal checking unit(200) receives a transmission local signal, a reception local signal, and a UHF(Ultra High Frequency) local signal from an SYNU(Synthesizer Unit) and the switching control signals from the signal control unit(100), checks states of the transmission local signal, the reception local signal, and the UHF local signal, and displays the checked states. The signal checking unit(200) receives the first and second reception output signals from a DOCU and the switching control signals from the signal control unit(100), checks states of the first and second reception output signals, and displays the checked states. |
