Accurate yaw rate stimulus requires not only good control of the handler, but well aligned DUT and low noise testing conditions. Infinite turning range helps to achieve higher yaw rates and gives more time to measure.

Multiple touchdown method - the way to high UPH

Presentation explains why multiple touchdown method gives much higher UPH than Single touchdown method used by traditional gravity and pick&place handlers

Low-g stimulus accuracy

Turning accuracy, DUT allignment and electrical and mechanical noise during testing and calibration have an impact to sensor performance
