The present disclosure relates to the technical field of mobile terminal production, and discloses a sensitivity testing method, a sensitivity testing device and an inspection apparatus for a GSM (Global System for Mobile Communications) communication terminal. The sensitivity testing method comprises: acquiring an RX Quality; determining whether the RX Quality is less than a step threshold that is set in a system; and if the RX Quality is less than the step threshold that is set in the system, then reducing a TCH (Traffic Channel) Level of the GSM communication terminal by one step. By using the RX Quality indicator in testing of a GSM communication terminal, the present disclosure determines whether the RX Quality is less than the step threshold that is set in the system, and adjusts the TCH Level of the GSM communication terminal according to the determination result.
