Abstract: he simultaneous data acquisition system with multi-channel and large-capacity is the important equipment in the flow-field match test of aircraft inlet / engine and vibration mode test of aircraft,ships and automobiles.The block A/D and store-while-acquisition techniques are proposed. Experimental results show that these techniques are effective in realizing the simultaneous data acquisition system with multi-channel and large-capacity.

Key words: data acquisition, multipath transmission, single channel per carrier transmission
