Abstract
A method for controlling operation of a transmitter in an electronic article surveillance (EAS) system is described that includes coupling each of a plurality of transmit channels to a corresponding antenna, configuring a modulator within each transmit channel to output a modulated signal to the corresponding antenna, providing feedback of each modulated signal, and adjusting operation of each modulator based on the feedback. An EAS transmitter and an EAS system are also described.
