Triggering analogue input from TTL signal

I am trying to acquire engine cylinder pressure data using LabVIEW and a
PCI-6023E board.

I want to acquire a single analogue voltage from ACH0 from a flywheel
encoder which sends a TTL pulse each crank angle.

The online help, etc. doesn't quite seem to get it right. I have to
manually adjust the sample rate to get it to acquire 360 samples per
revolution, i though this was the point of triggered acquisition not to have
to do this!!!

Any help/example code would be appreciated. My email address is ttbrb at
student.lboro.ac.uk

Thanks,
