Configures the device to wait for a digital edge Start Trigger at the beginning of the acquisition.

You can use this trigger with the NI-TClk API.

Note The PXIe-5644/5645/5646 does not support the NI-TClk API.
Note This VI is not supported if you set the acquisition type input to Spectrum using the niRFSA Configure Acquisition Type VI or if you set the Acquisition Type property to Spectrum.

Supported Devices: PXIe-5644/5645/5646, PXI-5661, PXIe-5663/5663E/5665/5667/5668, PXIe-5820/5830/5831/5832/5840/5841/5842/5860
