9.Easy to optimize various experiments.
10.File recycle function:for previous curve,if forgot save or the computer happen some special condition,it can recycle files,experiment data can user-defined keep time,when need you can recycle unsaved or broken file’s experiment data,ensuring the experiment will not lose in any condition.
11.Ecg function: through the software, it can also be switched to the whole-lead electrocardiogram amplifier in real time, complete the collection and processing of ecg signals, and switch the lead mode of the software. Ecg measurement function: it can process the ecg heart rate, P amplitude, PR period, QRS duration, ST, T amplitude and QT, and can directly enter into Excel, SPSS, SAS and other processing software.
12.Seamless joint to Microsoft Word Excel Access,with specialized processing software module of medicine statistic function,various processing method,precision.for different biological signal that with real-time and special processing method and smaller result error. There are many special analytical algorithms in the field of neuroelectrophysiology, electromyography and pharmacological toxicology of new drugs.

13.File printing function: can edit the experimental curve arbitrarily, save, seven print edit mode and full file pre-cable printing function. Can edit the graphics and the text size, the graph of the coordinates form, color and other graphic properties. And can add, delete, copy, copy the graph arbitrarily.
14.Data export function: can export the experimental data, the configuration of experimental parameters, etc., and can draw out some of the necessary channels to export separately. Signals that are too large for sampling can also be compressed by time to compress the data
15.Biological signal collection processing system can install and run in Window 7
16.High integration, using the USB2.0 interface, completely rid of the built-in, mobile convenience, convenient research
