It is very important for machine equipment fault diagnosis that how to fred the machine fault and take adaptive measures to deal with it accurately and in time. A kind of portable data-acquisition and signal-analysis instrument based-on Linux is realized in this paper. The instrument, which combines the functions of data acquisition ,signal analysis and data transfer, is very suitable for machine equipment fault detection and diagnosis. Firstly, the hardware structure is introduced in the paper. Then the software realization and some key techniques in the developing process are introduced. Finally, an experiment is given to prove the usability and correctness of this instrument, the result is fine. It shows that there will be a good value in the application of this instrument.
