better off setting the waveform record TSE=<the number of some event

in your timing system event receiver associated with the pulse>.

When using TSE=event# do be aware that there are several potential

races. One is that the data update from your digitizer driver may

arrive and be processed before the updated event timestamp from the EVR.

This should be avoidable in an RTOS if the interrupt and thread

priorities for the two drivers (digitizer and EVR) are picked appropriately.
