We should be able to do two side by side. I think it would be nice to be able to select the input daughtercard separately from the output daughtercard. This would require having two sets of pin headers for sending power and digital signals, but I think the input daughtercards would likely have much less in terms of digital control signal requirements; there would be two basic designs, one for baseband digitization and one for downconversion before digitization. Both designs would just have analog components, no digital attenuators/switches/etc would be necessary or desired. This would especially hold true if we go to a 4 DAC / 2 ADC design, but a 4/4 design should work fine too. _______________________________________________ ARTIQ mailing list https://ssl.serverraum.org/lists/listinfo/artiq
