ABSTRACT:
A method and apparatus for acquiring an analog signal. The method of the invention comprising the steps of acquiring a first portion of the analog signal by a first channel, the first portion of the analog signal spanning a first bandwidth range, and acquiring a second portion of the analog signal by a second channel, the second portion of the analog signal spanning a second bandwidth range adjacent the first bandwidth range. At least one spur in the signal acquired by the first channel corresponding to a portion of the analog signal that should have properly been acquired by the second channel is offset with an opposite spur in the second channel.
