Consider of characteristic of airborne product,and for saving the cost of the research design,we develop a kind of extensive temperature accommodated and reinforced recorder,research put emphases on making device generalize,modulize,easy used and mensurability.

this method is based on DSP processor,we can realize signal processing computer and digital recorder communication directlly through link ports and data ports of recorder.
