According to the requirements of a recorder mounted on the shell, combined with VB6.0 GUI which has the characteristics of simple development and efficient programming, and the powerful data processing ability of MATLAB R2016a, designed and implemented a PC software which include instructions issued, information analysis, reading data back and data processing based on the mixed programming. The software includes ground simulation source testing, data read back and data processing. Instructions are issued through a serial port, and read back dates by the 100M EMAC, separated and parsed by channel, output source data and the corresponding physical quantity file. After testing, the software can give precise instructions, and get the parameter information in time after the flight test to meet the work requirements.
