4 IN - 1 OUT dCSS Module
The SD-Z dCSS Module is a digital channel stacker that combines four wideband ADCs, a digital crossbar switch, 32 high-speed channelizes, one RF output DAC, and an acquisition process.
The SD-Z directly samples each of the four 170 ~ 2350MHz input signal feeds. Up to 32 channels from the four input feeds can be digitally selected, filtered, and independently converted to the desired location in the 170 ~ 2350MHz output spectrum. One RF DAC with a 5GHz sample rate directly drives the analog output.
