介绍了一种基于GPIB测试仪器和VisualBasic6、Access2 0 0 0数据库的卫星信号采集与处理自动测试系统。本系统实现了多颗卫星数字信号的自动提取和管理 ,正确测量出较宽频段中数字信号的频率、3dB带宽和信噪比 ,与手动测试相比 ,效率显著提高。
An automatic test system for satellite signal acquisition and processing based on GPIB test instrument, Visual Basic 6 and Access 2000 database is introduced. The system realizes the automatic extraction and management of multiple satellite digital signals, and correctly measures the frequency, 3dB bandwidth and signal-to-noise ratio of the digital signals in a wider frequency band. Compared with the manual test, the efficiency is remarkably improved.
