EMxpert In Action
EMxpert is a real-time, compact, bench-top EMC/EMI diagnostic tool enabling designers to rapidly diagnose & solve EMC/EMI problems in a single design cycle. Gain insights about why designs fail something no chamber can give you. No more waiting for chamber time to redesign & test by trial & error. The EMxpert rapidly diagnoses even intermittent problems, which may go undetected when using handheld and automated probes.

Application Notes for EMxpert

RFxpert In Action
RFxpert is the only real-time, compact, bench-top antenna measurement equipment.  In less then a second, unique array of automatically switched probes calculates accurate far-field (FF) patterns and radiated pwoer levels based on very-near-field (NF) measurements.  Immediate access to FF data saves time and cost by reducing reliance upon time consumng and costly anechoic chambers.  Unique NF data provides insight into the root cause of problems.
