(1) The input fullscale at minimum attenuation can be reduce by adding a digital gain range to the DSA, extending the useful range of the DSA. The noise figure remains constant over the digital gain range.
(2) After HD2 trim on specific printed circuit board.
(3) From DSA = 3dB down to 0dB, NSD increases 1dB per DSA dB
(4)   NF increase 1dB per DSA 1dB above DSA = 3dB
