Analog Input Channels
An evolution of the PCI bus, PCI Express maintains software compatibility with PCI but replaces the parallel bus with a high-speed (2.5 Gb/s) serial bus. It sends data through differential signal pairs called lanes, which offer 250 MB/s bandwidth per direction per lane. Unlike PCI, which shares bandwidth with all devices on the bus, each PCI Express device receives dedicated bandwidth. With its high bandwidth and low latency, PCI Express is an ideal bus for high-performance data acquisition.
