| Abstract: | Aiming at the less number of channels and not flexible scanning of Vxibus C-Size data acquisition module now, the paper studied the primary design method of multi - channel data acquisition module. And it presented the solution to some key problems, such as flexible scanning, automated calibration, data memory and so on. And DSP was assigned to be the local CPU, which strengthened the accuracy and function of the module greatly. |
