Relative phase angle between two accelerometers can be computed from the Transfer Function or complex division of Rover-accel. by Reference-accel.. This requires a two-channel analyzer (DAQ) with simultaneous sampling.

The other method is to use a Tachometer (1xSS) as the Reference and compute phase of each accelerometer referenced to the Tachometer Shaft Marker position.
