DDS(直接数字频率合成)技术是一门在频率合成领域的新兴技术,具有响应时间短,精度高等优点。而PLL(PhaseLockedLoop)锁相环技术虽然工作速度慢,但稳定可靠。VXI总线具有灵活、体积小、可移植好等特点,VXI总线测试平台是21世纪公认的仪器总线系统和自动测试系统的优秀平台。VXI总线模块仪器的优点是宜于集成为不同用途的自动测试系统,具有优良的交互操作性,数据传输速率高,可靠性高,易维修,体积小,重量轻,功耗低,可移动性好,价格与传统的自动测试系统相比具有巨大的竞争潜力。
DDS (Direct Digital Frequency Synthesis) technology is an emerging technology in the field of frequency synthesis with short response times and high accuracy. The PLL (PhaseLockedLoop) PLL technology, although slow, but stable and reliable. VXI bus has the characteristics of flexibility, small size and good portability. The VXI bus test platform is an excellent platform recognized by the 21st century as an instrument bus system and an automatic test system. The advantages of the VXI Bus Module instrument are that it is suitable for integration into automated test systems for different applications, with excellent interoperability, high data transfer rates, high reliability, easy maintenance, small size, light weight, low power consumption, mobility Well, the price has huge potential for competition over traditional automated test systems.
