The invention relates to a multifunctional carrier module tester. The multifunctional carrier module tester is characterized by being composed of a main control board circuit, a multi-path switching circuit and a carrier interface circuit, wherein the main control board circuit is connected with a multi-path switching chip of the multi-path switching circuit by an I/O (Input/Output) interface; the multi-path switching chip is connected with a carrier chip of the carrier interface circuit by a corresponding pin. The multifunctional carrier module tester can support carrier controller modules of all factories; only the modules need to be replaced aiming at carrier schemes of the different factories, so that the testing working efficiency can be greatly improved and the multifunctional carrier module tester is simple and rapid to operate.
