Configuring the PXI Trigger Bus Chassis Trigger Lines
Chassis Trigger Lines
A PXI chassis backplane includes repeaters to route a trigger line across a bus
segment boundary. When the repeater is activated, via configuration, it relays
trigger signals asserted in the source trigger bus segment to the destination
trigger bus segment. The repeaters relay trigger signals between bus segments
in either direction, but not both directions at the same time (on a single trigger
line) – so one repeater allows a signal to be routed from bus segment 1 to bus
segment 2, and another repeater is used to route the other direction from bus
segment 2 to bus segment 1.
Viewing chassis trigger routes and reservations graphically can be done using
the Keysight IO Libraries Suit Connection Expert which provides the Chassis
Triggers View.
Clients must also free their trigger resources when complete to
make them available again for use by other applications.
