2.4.1. Position Synchronized Output (PSO) Interface
This output signal is a 5V TTL signal which is used to drive an opto coupler or general purpose TTL
input. This signal is active high and is driven to 5V when a PSO fire event occurs.
You can use the external PSO synchronization functions to synchronize waveform generation with
an external synchronization signal. When you activate this feature, the PSO Waveform module will
not generate the configured waveform when an output event is received until the rising edge of the
synchronization signal occurs.
