摘要
本文介绍了由IBM-PC/XT微机与DL2800瞬态记录仪组成的自动测试系统。该系统能对多路信号以两种采样率同时采样,且采样率能跟随信号频率的变化,特别适合于对交直交变频系统的采样分析。
An automatic testing system consisted of IBM-PC/XT microprocessor and DL2800 transient recorder have been introduced in the paper. The system can sample multiway signals with two sampling rates at the same time. Besides, the sampling rate can change with signal frequency. It is especially suitable for sampling analysis of AC-DC-AC variable frequency system.
