Relay node simulator and test method

A relay node simulator that outputs a test signal obtained by simulating a signal in which a first RF signal transmitted from a base station and a second RF signal that is transmitted to a mobile communication terminal by a relay node that receives the first RF signal are multiplexed, the relay node simulator comprising:

• a user interface unit that displays an operation screen and receives an operation input from an operator;
• a marker display control unit that correlates a base station marker corresponding to the base station, a relay node marker corresponding to the relay node, and a terminal marker corresponding to the mobile communication terminal to a predetermined coordinate system and allows the markers to be displayed on the operation screen, and that allows at least one of the markers to be displayed on the operation screen in a movable manner in accordance with the operation input;
• a position specifying unit that specifies respective positions of the base station marker, the relay node marker, and the terminal marker in the coordinate system;
• and
• a pattern display control unit that allows a magnitude of a characteristic value relating to the first RF signal or the second RF signal to be displayed on the operation screen as a discriminable pattern (G11, G21, G22, or G31),
• wherein, when a position of at least one of the respective markers is specified in the pattern, the test signal to which the characteristic value corresponding to the specified position is applied is output.
