The compositive tester uses 12digit high-speed A/D converter. The speed reaches 10MHz when sampling. It can test the wave shape of a single high frequency wave. Also, it provides reliable methods for the researchers to develop the ballast working principle and analyze reliably. It meets the ballast and fluorescent lamp as well as the electrical capability testing requirements of IEC60929,IEC60969，IEC61000-3-2.
