In recent years, along with to the power supply products diversity and complexity of the requirements of the increase, how to scientifically and rapid detection of the performance index and become a big problem. The original manual measurement mode can't meet the production factory and the user's requirements, test automation become power module test the pursuit of the goal.

As the virtual instrument technology and computer measurement technology development, make in the traditional power test field into computer virtual test technology become possible. According to the demand of the market, the design of a new power supply test instrument, it USES digital adjustment and computer analysis is given priority to virtual measurement method, replace the original analog measuring method, realize accurate and fast measurement power supply products of various performance indicators, and can make all kinds of data statistics and analysis
