  • TSE = -1 for a fast and simple PV, e.g. an IP330 analog input using I/O Intr and an external EVR trigger. The most recent beam code is used, so processing must complete in 8.33 ms
  • TSE = -2 if device support will handle the time stamp. For example, device support code may call evrTimeGet at the beginning of processing, so it has the time stamp corresponding to when data was read even if processing that data takes longer than 8.33 ms
  • TSE = an event code #. The time stamp for the most recent trigger for that event code will be used, even if processing takes longer than 8.33 ms. This can be used if data is not synchronized with the beam, but you want the time stamp to correlate with other data. If SCAN is also using an event code, make sure SCAN sure EVNT and TSE match.
