The invention provides a calibration matrix device for calibrating a test system. The calibration matrix device comprises: a first SP8T basic switch unit and a plurality of second SP8T basic switch units; one end of the first SP8T basic switch unit is connected with a program control interface, the other end of the first SP8T basic switch unit is connected with eight second SP8T basic switch units; among the eight second SP8T basic switch units, each second SP8T basic switch unit has eight calibration channels, then the eight second SP8T basic switch units have 64 calibration channels in total, and the 64 calibration channels are in one-to-one correspondence connection with channels of the test system directly. The system calibration workflow is simplified; and an automatic calibration unit greatly reduces the calibration workload, solves the calibration problem of the test system of the large-scale channel equipment, improves the working efficiency, and reduces the costs of labor andhardware. 本发明提供了种对测试系统进行校
