Claim:
1. A test apparatus for testing a base station of a wireless communication system, the apparatus comprising: a downlink port, which receives a downlink signal from the base station; an uplink port, which emits an uplink signal to the base station; a signal processing unit, which is coupled to the downlink port and analyses the downlink signal for timing information and generates a timing synchronization signal based on the downlink signal; and a signal generator, which is coupled to the signal processing unit and the uplink port and generates a predetermined signal frame and emits the generated predetermined signal frame based on the timing synchronization signal via the uplink port to the base station, wherein the signal generator comprises a data memory, which stores a number of data frames, wherein, when generating the predetermined signal frame, the signal generator reads one of the stored data frames from the memory.
