Well, I have used WinNT4.0Workstation and Visual Basic 6 to obtain realtime
data from a board interfaced to a quadrature signal as a means of measuring
the height of gas turbine engine blades. It worked quite well, and I was
easily able to make 500 such measurements per second.

The board simply supplied the current value from the quadrature signal, and
in no way supplied a time base for capturing the value. The time base came
from the VB program.
