Since a common satellite has a plurality of data transmission channels, the conventional test method is to test the test items one by one in series for each channel, and the method has the defect that the required time is multiplied. If a plurality of channels are tested in parallel, a plurality of sets of test equipment are needed, and the test cost is too high. How to rapidly complete the index test of a plurality of data transmission channels under the condition of not increasing test equipment has important significance for reducing cost and improving test efficiency.
