M9005A Chassis Backplane Overview

PXI Local Bus

The PXI backplane local bus is a daisy-chained bus that connects each
peripheral slot with the adjacent peripheral slots to the left and right (refer to
Figure
The backplane routes PXI Local Bus 6 between adjacent PXI slots. The left local
bus 6 from slot 2 is not routed anywhere and the right local bus signal from slot 6
is not routed anywhere.
Local bus signals may range from high-speed TTL signals to analog signals as
high as 42 V.

PXI Trigger Bus

All slots share eight PXI trigger lines. You can use these trigger lines in a variety
of ways. For example, you can use triggers to synchronize the operation of
several different PXI peripheral modules. Modules can pass triggers to one
another, allowing precisely timed responses to asynchronous external events the
system is monitoring or controlling.
The PXI trigger lines allow you to send trigger signals to, and receive trigger
signals from, every slot in the chassis. Static trigger routing (user-specified line
assignments) can be configured through Keysight Connection Expert. Dynamic
routing of triggers (automatic line assignments) is supported through certain
Keysight drivers.
