PROBLEM TO BE SOLVED: To provide a test jig for efficiently measuring an antenna multicoupler. SOLUTION: In the test set provided with four terminals for measuring instrument connection for connecting a four-port network analyzer and the required number of terminals for connecting object to be measured for connecting the antenna multicoupler, arbitrarily selected two of antenna connecting terminals of the antenna multicoupler and the terminals for radio transmitter connection are checked of the conduction to two measuring ports of the four-port network analyzer, and arbitrarily selected two of terminals for radio receiver connection of the antenna multicoupler are checked of the conduction to the other two measuring ports of the four-port network analyzer, respectively. |
