An opened instrument with liquid crystal display (LCD) for generating and measuring physiological signal is introduced in this paper. Based on a single-chip microcomputer. the instrument uses the technique of LCD screen to display signal wave and information, and it realizes man-machine interaction by keyboard. This instrument can produce not only defined signal in common use by utilizing important saved data and relevant arithmetic, but also user-defined signal. Therefore, it is open to produce signal. In addition, this instrument has strong extension because of its modularized design as computer, which has much function such as displaying, measuring and saving physiological signal, and many features such as low power consumption, small volume, low cost and portability. Hence this instrument is convenient for experiment teaching, clinic examining, maintaining of medical instrument.
