PROBLEM TO BE SOLVED: To provide a broadcast signal receiver tester capable of accurately reproducing radio wave propagation environments of actual fields and evaluating performance of a broadcast signal receiver disposed on a vehicle and characteristics of a reception antenna connected to the broadcast signal receiver. SOLUTION: The receiver tester comprises a signal recording device 500 equipped with a broadcast signal receiving antenna 510 and a signal recording section 520 to record broadcast signals and a signal reproduction device 600 equipped with a signal reproduction section 620 to reproduce broadcast signals recorded by the signal recording section 520 and a transmission antenna 610 to transmit the reproduced broadcast signals, wherein the signal reproduction section 620 sets reproduction conditions to control and set at least one of delay and gain quantities of the broadcast signals to be transmitted so as to maximize the correlation value of the broadcast signal recorded by the signal recording section 520 and the broadcast signal which is obtained by reproducing the broadcast signal recorded by the signal recording section 520 by the signal reproduction section 620, transmitting the broadcast signal through the transmission antenna 610, and recording the signal again by the signal recording device 520.
