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, stimulator photoelectric isolation, stimulation waveform can be based on user need to edit, with two methods of constant current, constant voltage output, built-in stimulator range: 100 v (40 ma), step length: 5 mv (1 ma), pulse width: 2000 ms, step length: 0.05 ms 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, consists of the following special experimental data measurement functions: hemodynamics experimental parameters measurement, measuring the parameters of myocardial cell action potential, cell number of discharge measurement, the calculation of PA2, complete the LD50 of calculation in the method of Bliss, t test calculation, etc.
