Exposure Acquisition System for Up To 4 High Precision Field / Temp Probes


Download Product Flyer (PDF, 702 KB)

EASY4 is a complete stand-alone measurement system which provides high precision, multi-channel electromagnetic near-field, SAR, and temperature evaluations. Up to 4 probes can be connected via individual Data Acquisition Electronics for EASY4 (DAEasy). Each measurement channel is characterized and processed individually. The measurement system is user friendly and enables high precision isotropic measurements from lower MHz to above 10 GHz with a spatial resolution of a few millimeters.
