PXI

This section contains information about integrating NI digital waveform generator/analyzers into a PXI-based measurement system.

The PXI architecture has built-in timing and triggering features that can synchronize multiple devices using the PXI trigger bus lines on the PXI backplane. Multiple devices in a modular instrumentation system can share a common Reference clock and synchronize to triggers that are distributed over controlled signal paths that ensure matched propagation. PC plug-ins with RTSI also provide an internal bus that can be accessed by multiple devices. Internal routing of these timing signals in PXI (and PC plug-ins with RTSI) eliminate complicated external wiring and the need to calculate propagation delays. Standardized timing protocols eliminate incompatibilities, giving you the best performance when synchronizing any kind of analog, digital, or timing measurements.
