As a new type of spectroscopic devices, acousto-optic tunable filter(AOTF) has been widely used in spectral detection. Firstly, the dispersive principle and drive performance of AOTF were introduced, and some key performances of AOTF were discussed. Secondly, a set of analysis system for these performances was proposed. This system, with a monochromator as the light source, was based on multi-band acquisition, and was used to test the parameters of broad-spectral-range AOTF such as relation between driving frequency, diffraction efficiency and spectral resolution at different wavelength. The spectrum range covered from 400 nm to 3 200 nm. The intensity stability of light was better than 98%. The spectral resolution was less than 0.4 nm at 450 nm, 2.0 nm at 2 400 nm. Taking short-to-middle wave infrared AOTF as an example, the function and performance of the analysis system were verified finally, and the result shows the system suffices requirement of the design, and because of the high efficiency and convenience, the system has a high value for engineering application.
