PXI Trigger Bus Signal Routing

An IF digitizer can send and receive signals through the PXI trigger bus.

Signals can be routed to and from the PXI trigger connector of your device. All signal routing operations can be characterized by a source and a destination. The possible signal routes for your device depend on the device, the PXI chassis, and the occupied PXI chassis slot. Refer to your chassis documentation to determine the configuration of PXI trigger bus segments of your chassis.

When a signal is exported to a PXI trigger line from a device, only devices in the same PXI chassis segment recognize the signal from that PXI trigger line. To route the signal to devices in a different PXI chassis segment, you must establish a static route. A static route is a type of signal route that you must create manually.

Note Currently, the LabVIEW Instrument Design Libraries for IF Digitizers support only static signal routes, except in cases where the IF digitizer is used in a vector signal analyzer running NI-RFSA driver software. Refer to the NI RF Vector Signal Analyzers Help for information about signal routes for a vector signal analyzer using NI-RFSA.
Note PXI trigger bus lines are shared globally across devices in a chassis. The availability of PXI trigger bus lines may be affected by other applications that share the chassis you are currently configuring.
Note An IF digitizer can also send and receive signals through the front panel connectors. The front panel connectors provide connectivity for the input and output signals and for the control lines that send and receive clocks, triggers, and events.
