You can use three external trigger signals to start or stop the data acquisition. The trigger
signals are available on the SubD-9 socket connector of the DPA-400. Please refer to the

dialogs to control the triggers functionality.
The HPD_IO signal is also available on this connector to provide you an easy measurement
access to the HPD signal driven by your DisplayPort™ sink and connected to your
DisplayPort™ source device.
