Signal Routing for PCI Devices

NI Digital Waveform Generator/Analyzer

Signal Routing for PCI Devices

You can use the RTSI trigger bus to send and receive events, triggers, and Sample and Reference clocks. For more information about triggers, events, and clocks, refer to Dynamic Generation Triggers and Events, Dynamic Acquisition Triggers and Events, and Clocking.

All signal routing operations can be characterized by a source and a destination. The following table summarizes the possible sources and destinations for NI 654x/655x/656x signals. Sources are listed in the far left column, and the possible destinations span the top of the table. Some of the internal signals are broken into separate columns for generation (Gen) and acquisition (Acq).
