Triggering & Synchronization
The PXI bus combines the high-speed PCI bus with timing and synchronization designed specifically for measurement and automation. The PXI trigger bus consists of 8 shared trigger bus lines, a low-skew star trigger, and a common 10 MHz system reference clock. Using these synchronization features, you can easily pass trigger, clock, and other signals between PXI modules to make the accurate, high-performance measurements that you need.
