Brief introduction: 1. The instrument is compact and USES the integrated anti-jamming power supply, power supply ac 220 v, in addition to the case with a built-in transformer, external without any transformer, to ensure that the instrument in any bioelectricity experiment, without any external ground to ensure that the display of biological electrical signals clear and accurate.So as to ensure the anti-interference performance and accuracy. 2. The instrument has four channels (eight channels are 8 channels), all of which are multifunctional full-programmed isolated amplifiers.Each amplifier can be used as bioelectric amplifier, blood pressure amplifier, bridge amplifier, lung volume, thermometer, etc.Moreover, each channel has its own hardware module, which is independent from each other, greatly increasing the anti-interference ability between channels and bringing great convenience to maintenance and repair of instruments. 3. High precision 16-bit A/D conversion chip is adopted, and the maximum sampling rate of single-channel hardware is 1000KHz.Hardware minimum sampling rate 0.01Hz.The maximum sampling frequency of the four-channel continuous sampling is 200kHz, and the sampling rate can be changed as required in the process of real-time sampling.Scanning speed: 0.05ms/div~3200s/div. 4. The amplifier input resistance 100 m or more Ω (double side input) and 50 m Ω (single-ended input), common mode rejection ratio of 100 db or higher, plus or minus 1 mu or less noise V (RMS) or + / - 3 or less u V (P - P).Frequency response: DC~20kHz.Input range: 5 tells V~500mV. Sensitivity: a) bioelectric mode: 20uV/div~500mV/div b) blood pressure mode 3.6-360(mmHg/div), 0.36-180(mmHg/div)(high sensitivity transducer) 5. Both ac and dc have the same gain: the range is 500mv, 200mv, 100mv, 50mv, 20mv, 10mv, 5mv, 2mv, 1mv, 500uV, 200uV, 100uV, 50uV, 20uV and 10uV.The 10V signal can be directly input and the amplifier is unsaturated. 6. Low-pass filtering (hardware) : 0.3hz, 3hz, 10Hz, 30Hz, 100Hz, 500Hz, 1kHz, 3kHz, 10khz, OFF (20kHz).It has more than 5 - order filtering methods. 7. Time constants (hardware) : 0.001s, 0.002s, 0.02s, 0.2s, 1s, 5s, DC. 8. Photoelectric isolation programmable stimulator of the main technical requirements: a single stimulus, series single, continuous single stimulus, double stimulation, series double stimulation, continuous double stimulation, timing, stimulus, increasing the intensity of stimulation, increasing frequency and increasing bandwidth, strong interval increasing stimulate, automatic string stimulation such as double stimulation mode.Maximum load current: 100 mA, with positive current and negative current output mode, meet the national standard for safe electricity consumption for experiments, and avoid electric shock caused by misoperation.Output voltage <=50V to meet the national safe electricity standard. 9. Digital filtering mode: 1) high and low pass, band pass and band resistance with adjustable filtering parameters. 2) zero phase shift digital filtering with adjustable order Numbers. 10. The hardware system includes lead ECG lead all CARDS, each channel can be as a way of 12 lead electrocardiogram (ECG), lead a programmable switching, a total of 12 lead ways: Ⅰ, Ⅱ, Ⅲ, aVR, aVL, aVF, V1, V2, V3 and V4 and V5 and V6. 11. The testing function of experimental environmental data can be used to measure and add the current experimental ambient temperature, atmospheric pressure and humidity in the experimental information as the environmental parameters of the instrument experiment. 12. It can be equipped with the medical network management teaching system to conduct the laboratory network teaching.
