Product description: 1. The external mode adopts USB2.0 full-speed transmission mode 2. 8 recording channels, isolating common mode rejection ratio >100dB 3. 16-bit A/D conversion chip is adopted. The highest sampling rate of single-channel hardware is 1MHz, and the lowest sampling rate of hardware is 10Hz 4. Low noise: the peak value of the equivalent input noise voltage is <2 confidence V, and the signal-to-noise ratio >80dB 5. Wide input dynamic range: the measuring range is 0.5V ~ 20 entropy 6. 5-order Bessel low-pass filtering: 1Hz ~10KHz 7. Time constants include: DC, 0.001s, 0.01s, 0.1s, 1s, 3s, etc 8. The stimulus is photoelectric isolated, and the stimulus waveform can be edited arbitrarily according to the user's needs. There are two ways of constant current and constant pressure output. The built-in stimulus amplitude is 100V (40mA), the step length is 5mV (1mA), the wave width is 2000ms, and the step length is 0.05ms 9. It has the function of monitoring and dropping 10. Multiple devices can be cascaded to form the new equipment of the new 16 sampling channel 11. Physiological, pharmacological and pathological physiological experimental items were set up in advance, and the number of experimental items was not less than 50 12. During real-time sampling, sampling rate can be changed at any time as required 13. Users can set 1-16 display channels as required (channel 9-16 can be used for analysis) 14. A context-related timely help system 15. It has the function of human lung ventilation analysis and can carry out experimental courses on lung function 16. With the function of three-dimensional spectrum analysis, the study of gastrointestinal electricity can be carried out 17. Including the following measurement functions of specific experimental data: measurement of hemodynamic experimental parameters, measurement of cardiac cell action potential parameters, measurement of cell discharge number, calculation of PA2, calculation of LD50 completed by Bliss method, calculation of t test, etc.
