摘要:

IEEE 1641标准是IEEE标准委员会制定的新一代面向信号测试标准;首先分析了IEEE 1641标准定义的信号静态模型和事件类信号类型,梳理了可程控测试仪器的常见触发模式;接下来,以任意波形产生器SC53204-J为例,研究了基于IEEE 1641标准的测试仪器信号同步控制方法,并对仪器能力建模、仪器驱动编程、信号资源管理等进行了研究,最后进行了实验验证;该信号同步控制方法已应用在某型自动测试设备的软件平台上;应用结果表明,该方法实现了面向信号的测试仪器同步控制,具有较强的适用性和较广的应用前景。

Abstract:

IEEE 1641 (STD) is a new standard developed by IEEE SCC20 for signal-oriented test. This paper first analyzes signal static model and event signal definition proposed by the standard, and combs common trigger modes of programmable instruments. Next, illustrated by the example of arbitrary waveform generator SC53204-J, it studies instrument synchronization control methods based on IEEE 1641 standard, and discusses instruments capability modeling, instruments driver programming and signal resource management. Finally, it verifies the method by experiments. The method has been applied on a software platform of an automatic test equipment. Application results show that this method implements signal-oriented instrument synchronization controlling, and has strong applicability and wide application prospect.
