Abstract: Since the commonly used wavelet analyzers are not satisfactory for their simple functions， bad integration and portability with a low speed of dealing with complex signal， an integrated frameset analyzer was designed based on DSP technology. Based on the newest theoretical achievements on wavelet all over the world， this integrated frameset analyzer was designed and developed with virtual instrument technology， integrated instrument technology and DSP technology. This instrument can realize the functions of the traditional wavelet analysis and the new approach on analyzing nonlinear and non-stationary signals which is called frameset transform. This analyzer has powerful abilities for signal analysis and can improve the speed of dealing with the signal， therefore it is very suitable for analyzing nonlinear and non-stationary signals in real-time.
