3U CompactPCI平台凭借其可靠性高、可用性好、便于扩展和维护等特点,已经在高档测量领域得到广泛应用。PXI规范在CompactPCI的基础上加以扩展,加入了时钟、触发等总线,成为新一代仪器的总线标准。因为PXI比3U CompactPCI增加了许多扩展,几乎占满3U PXI系统的J2,无法实现3U CompactPCI的后走线,而后走线正是3U CompactPCI平台的优点之一。凌华科技(ADLINK Technology)认识到PXI在这方面的局限性,近日推出了3U后走线系列采集卡、界面卡。
The 3U CompactPCI platform is widely used in the field of high-end measurement due to its high reliability, good usability, ease of expansion and maintenance. PXI specification expands on the basis of CompactPCI, has joined the clock, triggers the bus, become the bus standard of the new generation instrument. Because PXI adds a lot of extensions over 3U CompactPCIs, it can take almost any 3U PXI system of J2 and can not implement 3U CompactPCI rear traces, which is one of the advantages of the 3U CompactPCI platform. ADLINK Technology recognizes the limitations of PXI in this area and recently introduced the 3U trace line capture card and interface card.
