The following table describes the relationship of triggers and events in a dynamic acquisition operation. The sequence of triggers and events is shown in the Dynamic Acquisition State Diagram.

Triggers are received synchronously by the Pattern Acquisition Engine. The Ready for Start event and all re-exported triggers are asynchronously generated by the Pattern Acquisition Engine.

Trigger/Event Received From Exported To
Start Trigger The Start trigger can be received from a rising or falling edge on PFI <0..3>, RTSI<0..7> (PCI devices), PXI_TRIG<0..7> (PXI devices), or by matching/not-matching a pattern received on DIO<0..31>. The Start Trigger can also be sent by software. The Start trigger can be exported to PFI <0..3>, RTSI<0..6> (PCI devices), or PXI_TRIG<0..6>.
Reference Trigger The Reference trigger can be received on a rising edge on PFI <0..3> RTSI<0..7> (PCI devices), or PXI_TRIG<0..7> (PXI devices), or by matching/not-matching a pattern received on DIO<0..31>. The Reference trigger can also be sent by software. The Reference trigger can be exported to PFI <0..3>, RTSI<0..6> (PCI devices), or PXI_TRIG<0..6> (PXI devices).
Advance Trigger The Advance trigger can be received from a rising or falling edge on PFI <0..3>, RTSI<0..7> (PCI devices), PXI_TRIG<0..7> (PXI devices), or by matching/not-matching a pattern received on DIO<0..31>. The Advance trigger can also be sent by software. The Advance trigger can be exported to PFI <0..3>, RTSI<0..6> (PCI devices), or PXI_TRIG<0..6> (PXI devices).
Pause Trigger The Pause trigger can be received from PFI<0..3>, RTSI<0..7> (PCI devices), PXI_TRIG<0..7> (PXI devices), or by matching/not-matching a pattern received on DIO<0..31>.
Ready for Start Event
The Ready For Start event can be exported to PFI<0..3>, RTSI<0..6> (PCI devices), or PXI_TRIG<0..6> (PXI devices).
Ready for Advance Event
The Ready For Advance event can be exported to PFI<0..3>, RTSI<0..6> (PCI devices), or PXI_TRIG<0..6> (PXI devices).
End of Record Event
The End of Record event can be exported to PFI<0..3>, RTSI<0..6> (PCI devices), or PXI_TRIG<0..6> (PXI devices).
