In the paper,the design of a test system for a total of 13 chips on general purpose boards is introduced.In the design process,in order to save the cost and enhance the flexibility of the test device,the external power supply is provided by the program-controlled DC power supply.The drive board is replaced by a self-made circuit board with a digital channel of the data acquisition card,the board is provided with power supply and various control signals,the analog power is composed of external power resistors,providing signal monitoring points,and the signal acquisition module is composed of two eight-channel signal acquisition boxes,which are responsible for the acquisition of all monitoring signals during the entire test process.The host computer is responsible for controlling the switching of the drive board signal and the readback storage of the monitoring signal,while interpreting the data to obtain the complete state of the device under test.After testing,the test system test results are normal,and the devices under test are stable and available.It shows that the test system is complete and reliable,which meets the requirements of the chip data sheet and the needs of the actual project.
