一种数字电视接收机自动性能测试方法

Method for Automatic Performance Test of Digital TV Signal Receiver

提出了一种基于远程自动控制、针对数字电视接收机的性能测试方法。介绍了基于计算机平台、局域网、R&S-SFU的测试系统,基于LAN接口,利用NI-VISA标准API、SCPI命令集的驱动程序编写,以及利用驱动程序、自动测试程序的编写。研究表明,该方案为数字电视接收机的性能测试提供了一种简单、快速、准确、高效、灵活的选择。

A test method based on remote automatic control for digital TV signal receiver is proposed in this paper. Then, many important informations are introduced, such as the test system based on PC platform, Ethernet, R＆S-SFU. It also includes the driver based on LAN interface, NI-VISA standard API, SCPI commands, and the automatic test program based on the driver. Research shows that this method could be a simple, fast, accurate, efficient, flexible choice for performance test of digital TV signal receiver.
