High-speed input 8 can be used as a general purpose input or as the trigger signal for high speed data
collection. Refer to the DriveDataCaptureConfigureTrigger() function topic in the Help file for more
information.
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.
