A radio multichannel telemetry system has been developed for use with chronically instrumented, unrestrained, small animals. The system can simultaneously record autonomic neural signals, blood flow velocity, blood pressure, and ECG. The system is time-multiplexed and pulse width modulation (PWM)/FM device, which employs two sampling frequencies. The system is designed with 10 standard low power integrated circuits, a 3 terminal voltage regulator, and a transistor. The size is 53 x 42 x 20 mm, and the weight, including two batteries is 40 grams. The system is powered by two lithium cells, which provide 60 hours of continuous operation.
已开发出一种无线电多通道遥测系统，用于长期植入仪器、不受束缚的小型动物。该系统可同时记录自主神经信号、血流速度、血压和心电图。该系统是时分复用和脉宽调制（PWM）/调频设备，采用两种采样频率。该系统由10个标准低功耗集成电路、一个三端稳压器和一个晶体管设计而成。尺寸为53×42×20毫米，包括两节电池在内的重量为40克。该系统由两节锂电池供电，可提供60小时的连续运行时间。
