This paper introduces the design and test of data acquistion channel for the instrument of fault detection of gearing system of an internal combustion locomotive. The designed channel is composed of electricity amplifier, programmable gain amplifier, anti-aliasing low-pass filter, band-pass filter, etc. The designed data acquistion channel is simple and the circuit is debugged conveniently. The data channel meets the whole demands of the instrument for the fault detection.
