... Puppi uses an interleaved AtoD converter. ... SBW observations (on 7jan13) showed an image of the 2140 rfi at about 15 db below the rfi ( .png ). ... A simple simulation was done to see how sensitive interleaved sampling was to amplitude errors (.ps) ( .pdf ): . ... Amplitude scaling errors on the interleaved sampling will create an image. a/d offset errors added a DC spike. To get a 15db image you need an very large amplitude error (1.4 times the correct amplitude) . ... page up to puppi . ...
