An efficient test system based on the ceramic probe card and the preamplifier presented in this paper achieves a good solution for the impact from the distribution parameters in micromachined gyroscope chip testing.The frequency characteristic and the needed parameters（resonant frequency

Q value）are obtained appropriately.A 4-D precise displacement operation platform is designed according to the precision to adjust the position of the chip

and a microscopic video system is built to observe the chip conveniently and record the results.Virtual instrument is used for automating the test process.It is expected that the test system will play an important role in development and industrialization of micromachined gyroscope.
