	A high power CW, heavy ion linac will be the driver accelerator for the Facility for Rare Isotope Beams being designed at Michigan State University. The linac requires a Beam Position Monitoring (BPM) system with better than 100 micron resolution at 100 microamperes beam current. A low beam current test of the candidate technology, button pick-ups and direct digital down-conversion signal processing, was conducted in the ReA3 re-accelerated beam facility at MSU. The test is described. Beam position and phase measurement results, demonstrating ~200 micron and ~1 degree resolution in a 90 kHz bandwidth for a 0.5 microampere beam current, are reported.
