Secondary Power Supply Universal Test System Based on PXI Bus

The most research on the power supply test was aimed at the fields of aviation and communication now, but it had not seen similar test system of the missile. To address this problem, the measurement theory and achievement method of the secondary power supply test system based on PXI bus were elaborated in the paper. On the basis of analyzing the function and the quota of the system, the hardware platform based on PXI bus was built up, the modular software test process was achieved, and the software design of each module was completed on the development platform of Lab VIEW. It was proved that the test system has the merits of high precision, high reliability, good universality, and a short test time, and then it effectively improved the quick-reaction capability and viability of the missile.
