TESTING A COMMUNICATIONS APPARATUS

摘要

A test arrangement includes a multi-port test interface having a first waveguide coupled to a plurality of second waveguides. The first waveguide is arranged to propagate an input signal and each of the second waveguides is arranged to output the input signal, providing a plurality of test signals to be supplied to a communications apparatus. Such a test interface may also be used to output respective channel signals in a multiplexed signal received from a communications apparatus. The test interface permits the provision and/or monitoring of a large number of channel signals without separate respective connections to the communications apparatus. This may be particularly useful where tests are performed in a constrained space and/or where repeated access to the apparatus is impractical. The simultaneous provision of many channel signals may allow evaluation of co-channel interference.

1. A test arrangement comprising:
a test interface configured to provide a plurality of first test signals to an apparatus; wherein: the test interface includes a first waveguide, a plurality of second waveguides coupled to the first waveguide and a plurality of first ports corresponding to respective ones of the second waveguides; the first waveguide is arranged to receive a first input signal through a first input port; the first waveguide and the second waveguides are configured to propagate the first input signal; and the first ports are arranged to output the first input signal propagated in respective ones of the second waveguides as respective first test signals.
