With independent frequency tuning for each of the 256 digital down converter (DDC) channels, the Model 7151 can down-convert any signal within any of the four digitized 100 MHz input bands, significantly enhancing the efficiency and diversity of signal-intelligence applications. Arranged in four banks of 64 DDC channels, each bank can be configured for a unique output signal bandwidth to accommodate applications requiring mixed signal types or multiple modulation schemes. Each DDC bank can be independently sourced from any one of the four A/D converters, which are typically assigned to specific antennas.
