This paper has proposed a testing method that employs the DLM 8--channel oscilloscope to replace the traditional 4--channel osdlloscope method. It is based on the fact that in the Cannon development process, the oscilloscopes engaged in the current testing technolL ogy only have a few number of channels in a single device, which, when multiple devices have to be used collectively in a single time, would generate problems such as non--synchronized ＆ incompatible data, delays in displays, etc.. The advantages of the proposed method are as following： firstly, the use of DLM 8--channel oscilloscope method instead of the traditional 4--channel has ensured synchronous triggering of data acquisition, resolved the time delays and difficulties such as adequate analysis ＆ display etc.. Secondly through multiplexing, it is flexible enough to either increase the sampling rate or to capture a long record for a reliable data acquisition. Thirdly, given the functions, the proposed is cost effective. It is proven in a number of experiments that the DLM 8--channel oscilloscope testing method is capable of rectifying difficulties encountered in data acquisition during the process of Cannon development of high firing rate, which may requires multi ple channel data acquisition and display, fast sampling, long time recording and storage.
