Delcross EMIT is a commercial software package for predicting RF cosite EMI in complex RF environments containing multiple receivers and transmitters. EMIT can also be used for RF coexistence analysis to locate EMI margins between multiple RF systems incorporated within the same package or device. EMIT incorporates parametric models or measurements for antenna-to-antenna coupling, RF system (radio) models, amplifiers, cables and filters to provide a comprehensive EMI analysis for both in-band and out-of-band signal components.
