To meet the need of portability of outfield equipment test device and real?time transformation of signal acquisi?tion,an embedded system was set up by combing host computer control board and signal acquisition board,based on the advan?tage of high data transmission efficiency of PC104 bus. Configuration of multichannel switch,signal recuperation circuit and AD converter is realized by FPGA control logic on signal acquisition board. The acquired signal data is transmitted to host computer control board to display in real time. Application result shows that the system is easy to operate,and has perfect real?time perfor?mance and stability.
