。PXI吸收了VXI的优点，同时受益于Compact PCI（CPCI），因而速度更快、结构坚固紧凑、系统可靠稳定，在射频和微波频带以下的低、中高频段可以替代VXI而且价格优势明显，深受广大用户欢迎，目前正朝气蓬勃地向商用与军用领域拓展。-. VXI PXI absorbed the advantages of both benefit from the Compact PCI (CPCI), and thus faster, compact, rugged, reliable and stable system in the RF and microwave frequency bands below the low, medium and high frequency alternative to VXI obvious price advantage, by majority of users, is now a vibrant commercial and military areas to expand.
