ス１８を介して被試験体１６に注入することができる。When the wire harness 18 of the test object 16 is inserted into the insertion hole 29 from the insertion hole 28 through the groove 22a, the larger the diameter of the wire harness 18 and the larger the number of wire harnesses, the higher the number of high-frequency injection tubes 120. As the characteristic impedance becomes lower and the test frequency becomes higher, the decrease in the characteristic impedance becomes more remarkable. This decrease in characteristic impedance can be detected by measuring the standing wave ratio with the power meter 53. Therefore, when a decrease in the characteristic impedance is detected, the attenuation amount of the attenuator 54 is adjusted to adjust the level of application of an appropriate amount of high frequency current to the second internal conductor 51, thereby reducing the characteristic impedance of the high frequency current injection tube 120. and adjust it to a value that prevents standing waves from occurring. Then, there is no reflection of the high frequency current from the terminator 14 side, and therefore the high frequency current can be stably injected into the test object 16 via the wire harness 18.

In this embodiment, the second internal conductor 51 is configured with a wire harness, and a concave groove 22a passage for wiring the wire harness 18 of the test object 16 is similarly provided, and the second internal conductor 51 configured with the wire harness is 51 to obtain the same effect as the first embodiment.

A high-frequency current is applied to the second internal conductor, and the characteristic impedance of the high-frequency current resident tube is kept constant depending on the applied level, so that a decrease in the characteristic impedance due to wiring of the wire harness of the test object is suppressed. Because of this, high frequency current can be stably supplied without reflection of high frequency current, and as a result, EMC tests can be performed stably and with high reproducibility.
