We have developed a modern array driver employing multi-channel arbitrary waveform generator and linear amplifiers for transmit wavefront synthesis. The system utilizes deep waveform memory that can be configured for switching between transmit patterns seamlessly thus allowing for the use of spatial and frequency diversity in image acquisition. In this paper, we present the first experimental results demonstrating dramatic reduction in sidelobe artifacts as well speckle reduction.
