Brief introduction: RM6280C multi-channel physiological signal acquisition processing system developed by chengdu instrument factory is a new generation of medical laboratory equipment, adopting 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. The system adopts the real outer structure. Which is applicable to laptop, applies to desktop computers. There are usb model and the computer interface. Due to system internal A/D acquisition part adopts the independent circuit board (outer) inside the case, so no matter how to develop computer interface technology, after the instrument can be by changing the A/D acquisition module and the corresponding software to adapt to the development of the computer, instrument upgrade is very convenient. Stimulator adopts optical coupling isolation system, ECG has international standard 12 lead mode. Instrument to various options from the microelectrode amplifier electrode, convenience of transducer, screen, to ensure customer satisfaction to complete all kinds of electrophysiological experiment, this series of products for the isolation, both on the human body can also be used for animal experiment. Technical parameters: Sampling rate: a 400 kHz channel, two channel 200 kHz, three or four channel 100 kHz. Above is real-time display mode sampling rate of continuous recording to disk, and the sampling rate is adjustable. Scanning speed: 0.2 ms/div - 3200 s/div is adjustable. 100 m Ω amplifier input resistance: p, Common mode rejection ratio: 100 db or higher, Noise (fengfeng value) : plus or minus 3 mu V or less, Frequency response: DC ~ 20 kHz, The input range: 5 mu V - 250 mV, Zero: 12 resolution control software, can the scope of the selected range between 5% and 100%. Sensitivity: 1. Bioelectricity communication mode: 20, 50, 100, 200, 500, (mu V/div) and 1, 2, 5 (mV/div) 2. The bioelectricity dc and ac low gain mode: 1, 2.5, 5, 10, 25, 50, 100 250 mV/div. 3. Blood pressure patterns: 0.48, 1.2, 2.4, 4.8, 12 (kPa/div) or 3.6, 9, 18, 36, 90 mmHg/div Low pass filter: 0.3 Hz, 3 Hz, 10 Hz, 30 Hz and 100 Hz and 100 Hz, 1 KHZ, 3 KHZ, 10 KHZ, OFF Time constant (high-pass filter) : 0.001 s, 0.002 s, 0.02 s, 0.2 s and 1 s, 5 s, DC All isolation stimulator technical indicators: 1. Can produce single pulse, double pulse, series of pulse, and continuous pulse. 2. The pulse can be triggered manually or automatically. 3. The pulse parameters: stimulate constant pressure range (0 ~ 50) V (maximum pulse output current can be up to 100 mA) or (0 ~ 10) mA constant current Step 4. Pulse resolution: 1000 ms delay: (0.1 ~ 1000) wave interval (0.1 ~ 1000), ms Wave width (0.1 ~ 1000) ms frequency (1 Hz ~ 3000) 5. The output method: voltage of positive and negative voltage and current of positive and negative current 6. The isolation method: photoelectric isolation.
