Abstract

Mixed-signal and high-channel-count test systems typically require tight synchronization between instrument components. The PXI backplane contains system reference clock, PXI trigger bus, and star trigger bus resources designed for precise and flexible timing and synchronization. Engineers can take advantage of these resources to synchronize instruments across the PXI backplane using numerous synchronization schemes. Additionally, the PXI platform can be used to implement advanced timing and synchronization architectures such as the synchronization of instruments to external timebases such as GPS
