Brief introduction: Rm series of multi-channel physiological signal acquisition processing system (4, 8, 16) developed by chengdu instrument factory is a new generation of medical laboratory equipment, adopt the advanced electronic technology and digital signal processing technology. System, powerful and flexible set of biological signal acquisition, amplification, display, record and analysis into an organic whole, is a traditional medicine experiment system (consists of amplifiers, recorder, stimulator and oscilloscope) and upgrading of products. Features: 1. The signal collection and processing by the computer system. 2. Used for animal experiment: ecg, blood pressure, heart sounds, pulse, blood pressure, electrical, electrical, electrical, skin electricity experiment. 3. The external type, with functions of cascading expansion; USB2.0 high speed interface. 4. The highest continuous sampling frequency: the use of a channel up to 400 KHZ, use two channel up to 200 KHZ, using four channel up to 100 KHZ; Program-controlled sampling frequency is adjustable. 5. All channels for the multi-function program-controlled isolation amplifier (through the pattern choice, amplifier of each channel can be bioelectric amplifier, blood pressure amplifier, bridge amplifier is used, also can make spirometer (matching flow transducer), thermometer (matching temperature transducer), etc. 6. Scanning speed adjustable, each channel can be synchronous adjustment also can adjust the asynchronous. 7. High input resistance amplifier, common mode rejection ratio, low noise; Each channel amplifier isolation performance is good; No crosstalk between tao. 8. Amplifier wide frequency response, small waveform distortion; The input range is large; High sensitivity; Size can be read directly measured signal. 9. 8 hardware high and low pass filter, reasonable parameter Settings, SPC is adjustable. 10. Software digital filter high-pass, low-pass, band-pass, band-stop four patterns so the experiments to further improve performance. (arbitrary adjustable filter parameters) Technical indicators: High sampling frequency, 1000 KHZ (USB2.0 interface models) Scanning speed: 0.2 ms/div ~ 3200 s/div Amplifier input resistance 100 m or more Ω (double side input) Common mode rejection ratio of 100 db or higher Noise plus or minus 1 or less u V (RMS) or + / - 3 or less u V (P_P) Frequency response: DC ~ 10 KHZ The input range: 5 mu V ~ 500 mv Sensitivity: A) hybrid mode: 20 mu V/div ~ 500 mv/div B) blood pressure patterns: 0.48 ~ 24 (kPa/div) or 3.6 ~ 180 mmHg/div Low pass filter (hardware) : 3 hz, 10 hz, 30 hz and 100 hz and 500 hz, 1 KHZ, 3 KHZ, OFF Scaling type tension transducer measuring range: 0 ~ 50 g; Sensitivity: 100 mv / 30 g (6 v dc) Scaling type pressure transducer range: - 10 ~ 40 kpa; Sensitivity: 25 mv / 12 kpa (6 v dc)
