A multichannel waveform recorder is raised to solve the puzzling problem of failures of aircraft ground power sources. The hardware system is established with embedded single-board computer PC/104 and multichannel parallel data acquisition card, etc. Windows XP Embedded and LabVIEW are used in software architecture. Strategies for automatic segmentation of massive data block are proposed. System testing is done on the medium frequency electric power source. Testing results show that this multichannel waveform recorder is easy to operate, accurate in measurement, and has good stability and portability. It can be used to monitor power supply of aircraft ground electric power source for a longtime, and thus is of high practical value and economic significance.
