Technical parameters: 1. Transmission mode: USB2.0 high-speed;Sampling speed: 1000KHz/S(up to 1600KHz/S according to customer needs), sampling frequency can be adjusted at will. 2. Module (A/D) conversion accuracy: 16bit;Amplification factor (input range) : 5~50000 times program control switch. 3. Signal input channel: 4 channels, simultaneously sampling.Each channel is independent of each other, and the machine box is made up of multiple circuit boards, which is convenient for after-sales and maintenance. 4. Stimulus output channels: 2 channels with photoelectric isolation of the stimulator, which can output triangular, square, positive and negative square waves, sine waves and any waveform edited by itself at the same time.Constant current source, photoelectric isolation, seven stimulation modes: single stimulus, serial stimulus, main cycle stimulus, automatic frequency stimulus, automatic wave width stimulus, automatic amplitude stimulus, automatic interval stimulus.Full program control adjusts three sets of output: 0~5v, 0~10v, 0~100v (each shift can be adjusted at will).It also has the function of stimulus interruption. If you want to interrupt stimulus in advance, you can control the interruption of stimulus by software. 5. Marking function: it can mark any position of the experimental waveform at any time before, during and after the experiment.In addition, any number of channels can be marked together during the experiment to facilitate the recording and observation of pharmacological experiments. 6. Working voltage: this instrument introduces voltage of 220V/50HZ, which is in line with the international technical standard of physiological instruments. 7. Zeroing mode: automatic zeroing of hardware (different from software zeroing, and no manual manual transducer is required). 8. Filter type: 9th order butterworth. 9. Input noise: <2uv;Temperature drift: <2uv/4h;Common-mode rejection ratio: >120dB; SNR: >80dB. 10. Sampling mode: manual and automatic: automatic sampling can be carried out according to the set time to achieve real man-machine interaction. 11. Software interface: adopt international popular Internet explorer style and chinese-english interface to facilitate the research and exchange of international students. 12. Data statistics: various experiments have professional calculation templates.For example, electrocardiogram experiment: p-wave amplitude, p-wave time, r-wave amplitude, p-r time, QRS time, t-wave amplitude, t-wave time, q-t time, heart rate, etc. 13. Experimental module: open experimental module, users can add, edit and delete experimental template at will. 14. Storage mode: conventional storage, selective storage, record storage, power off storage (i.e. the file will not be lost in case of sudden power failure or other accidents). 15, in the process of the experiment such as hardware suddenly loses power accident, do not need to restart the software and save operation, just once again open hardware and can continue sampling, not cause data loss, ensure the consistency and integrity of the whole experiment. 16. Single window display: the four-channel waveform can be superimposed on the same baseline to facilitate longitudinal comparison of each experiment. 17. Extended function: besides routine experiments, scientific research experiments can be carried out, such as brain LTP experiments. 18. The third channel is specially equipped with a 12-lead automatic switching ecg machine, which has the function of ecg grid and is convenient for users to observe and analyze. 19. The device is automatically cascaded into more than four acquisition channels.Up to 32 channels can be displayed for data analysis. 20. Equipped with a camera module, video visual education system can be added to the system, and the image size, distance, clarity and other parameters of the camera can be adjusted through the software of the biological signal acquisition system.
