摘要
介绍了一个基于标准总线 VXI的四路门控积分器模块插件。在四路独立的纳秒门控积分电路的基础上 ,采用 VXI寄存器基接口实现对各路门控积分器的数据采集和控制 ,采用 Labwin-dows/CVI编写了数据采集系统软件 ,从而完成了纳秒级门控积分器的实用化的基本工作。
The design of a four-channel gated integrator system based on VXI bus containing functional circuit and interface circuit is introduced. It is a registered device which is configure registers and operational registers. This module is used to integrate the output current of X-ray diodes. The software of the data acquisition system, which has characters of virtual instrumentation, is also introduced. In electronic test, the system has good performance. The gate width in which the current is integrated is 10-12 ns, integral nonlinearity is less than 1% and there is hardly interference between channels. The maximum error between the results of this module and of oscilloscope is less than 2% of the scale range of the gated integrators. Through these tests, the module implements normalization, anti-jamming and practicality.
