Re: [casper] Application of SMA correlator design to a larger array

I can think of three ways to operate non-2^N antennas... 1) "fake" F-engine inputs: This is what MeerKAT does right now when it has fewer than 2^N antennas. We just multicast copies of redundant the data into unused F-engine inputs. It doesn't save you any hardware and is wasteful, because yo

Re: [casper] Application of SMA correlator design to a larger array

Hi Jason, Thanks for the quick estimate. If we are targeting 10 antennas, can't the correlator be made to work with only 10 F engines? The packets of the missing F engines would just not arrive at the X-engine, and hence the associated baselines would be zeroed or just ignored. We might also de
