The invention discloses a signal path controller, comprising at least one splitter; a plurality of matrix switches are connected among splitters; the splitter uniformly distributes output signals to the plurality of matrix switches; the plurality of matrix switches perform output switching on distributed signals, or a plurality of matrix switches receive extraneous signals and transmit the signals to the splitter for collection. The at least one splitter can be integrated through connecting with the plurality of matrix switches to form a plurality of point-to-point channels, and accordingly the splitter can be in connection with different test devices according to different test requirements, thereby avoiding tedious operation of a splitter point-to-point connection test device; the matrix switches can uniformly distribute signals to avoid deviation of electricity information collection.
