为了克服医学电子仪器往往不能同时产生和测量生理信号的缺陷，提出一种多功能生理信号产生及测量仪。该仪器以STM32F207VG微处理器为核心器件，软件用c语言编写，采用Keil C进行编译。不仅能够产生相位可控的正弦、方波、三角波等常用信号和心电、心音和脉搏波等常规生理信号以及临床上常见的异常生理信号，而且还能够同时测量多达8道的生理信号。本仪器可广泛应用于科研、教学、测试和仪器维修等。

In order to overcome that the present medical electronic instrument cannot produce and measure physiological signal simultaneously, a muhifimctien produce and measurement instrument for physiological signal was put forward. STM32F207VG is used as the core, while the program was written by the C language, and compiled by the Keil C. It could not only output high precision phase and controllable common signal sine wave, square wave and triangle wave, and measure up to eight channel physiological signal, but also produce the conventional physiological signals, for example cardiogram, heart sounds, pulse wave. And the common clinical abnormal physiological signals also can be produced by it. In addition, the instrument had a high drive ability of interface, which could be directly driven headphones etc.h can be widely used in scientific research, teaching, testing and instrument maintenance and so on.
