TMS320F28335-based high-accuracy complex network analyzer instrument

Preliminary prototype of the TMS320F28335- (digital signal controller-DSC)-based complex network analyzer instrument has been developed and investigated. High accuracy (16-18 bit resolution) and relatively wide analogue bandwidth (up to 10 MHz) is achieved by using of external ADC and DAC devices. Using of DSCs offer much computational power for real-time signal processing (efficient Dual MAC operation), dedicated memory and IO controllers (DMA) and flexible communication and peripheral interfaces at low cost and reasonable power consumption. Proposed solution has been developed, described and discussed. Performance estimations, both from theoretical considerations, as well as from experimental investigations, has been given. As a result, a a very promising technical solution has been developed. Main contribution of the current work has been practical implementation and investigation of specific (high-accuracy) analog interfaces and corresponding firmware parts.
