摘　　要：DSVM-1A型测振仪是一种由微机控制的无电缆袖珍式测试仪器。重点介绍了该仪器的组成、原理和参数选择等,并给出了应用实例的分析结果。The shortcomings of traditional vibration monitoring system mainly are: (1) it is very difficult to convert the output of the impact oscillation graph on the ultraviolet recording paper into numeric data, (2) for signal transmitting from measuring sensor to amplifier, there is a need of several dozens or hundreds metres cable. Unavoidably, environmental noise, mingled with the signal, will get to the input terminal of the amplifier, and this makes the system error larger. To solve the problems mentioned abo...
