The Rocking Analysis Module (RMA) is released now and has received substantial improvements to guide the user effortlessly from measurement to analysis. A clear indication is given if the device under test has a critical rocking behavior which may result in reduced output, audible distortion (Rub&Buzz) and early failure (field rejects). The actual scanning time for a rocking analysis takes usually less than 10 minutes. This allows testing multiple devices of one batch to isolate systematic behavior from random effects.
