I have been working with Labview off and on to solve vibration problems.
In rotating machinery, one must quite often sample vibrations for equally spaced angular positions of the shaft (indexed samples). I tried to do this with an ordinary MIO E cards. Found an interesting way to do this without an incremental encoder attached to the shaft and just a single phase reference, but couldn't test it with PCI MIO E cards. If someone is interested in this application (s)he can try it with the executable vi found in www.ulb.ac.be/polytech/laborulb/ordertrack/ordertrack.htm and report possible problems and even better solutions. Thanks and hello from Belgium
