Abstract
A digital programmable timing device to control the acquisition of data by a computer from high response probes in periodic flows. Synchronized sampling of probe measurements uses a phase-locked-loop and counting circuits so that the moment of AID conversion always corresponds to a programmable displacement of a stationary probe with respect to moving rotor blades independent of RPM. The rotor speed also is measured digitally in one revolution of the rotor shaft.
