Configuring a Trigger with a P2P Stream

Depending on the type of trigger configured for the acquisition, data is not written to the P2P endpoints in the same way as it is written to onboard memory.

Immediate Trigger

Because of differences in the data path leading to the P2P endpoints and the onboard memory, the first sample written to the P2P endpoints is from an earlier time than the first sample written to onboard memory.

Note   The record sent to the onboard memory is the same length as the record sent to the P2P FIFO.

All data written to the P2P endpoints is valid, but the samples are not aligned with the same record stored in onboard memory.

Configured Reference Trigger

When the trigger type is anything other than immediate, the digitizer sends all data between the Start trigger and the End of Record event to the endpoint.
