Using Expression Signal Routing
This section describes how expressions can be used to program signal routing. You can also use the
Power Assistant software to program signal routing. For an overview of how the expression signals are
mapped into the trigger system, refer to Trigger Overview.

Signal Routing Overview
You can configure up to eight flexible, general purpose signal routing expressions. These signal
expressions can be used to drive digital port pins, trigger measurements and transients, change
output state, generate user-defined protection and user-defined status signals. Expressions are built
using a large selection of signal inputs along with Boolean operators and programmable delays.
The following figure illustrates the signal routing paths:
