Working together w ith an existing hardw are part of a multi-channel data acquisition system, it could also achieve the functions of equipment reset, ad lock checking and erasing of the . , Flash T he main program of the softw are w as compiled in VB in which the chart draw ing function w as realized y calling the corresponding module of M atla . T he tw o key technologies the communication, principle etw een USB2. 0 and host computer and the data transmission mechanism etw een V B and M atla , w ere introduced. T he softw are had een successfully applied in many data acquisition systems. It w as proved that the softw are had the advantages of high efficiency of data transmission data analysis,
