    • A connector includes a connector housing that has a first terminal and an inner housing that has a second terminal, and is configured to be fitted into the connector housing so that the second terminal is connected to the first terminal. A first slanting face is formed on an outer peripheral face of the inner housing. The connector housing have a chamber for receiving the inner housing therein when the inner housing is fitted into the connector housing. A first prevention face is formed on an inner peripheral face of the chamber. The first slanting face is surface-contacted with the first prevention face when the inner housing is completely fitted into the connector housing.

    • A method for measuring an adjacent channel power of a device under test (DUT) such as a radio transmitter. The method comprises the steps of performing a frequency conversion to convert a transmitting signal of the DUT to an intermediate frequency signal; sampling the intermediate frequency signal to convert it to a digital signal; resolving the digital signal into an in-phase component and a quadrature component by a quadrature detection; removing a high frequency component from each of the in-phase and quadrature components; executing a complex Fourier transformation for the in-phase and quadrature components to obtain a frequency spectrum; and computing the leakage power to the adjacent channel from the frequency spectrum.
