Abstract

A digital down-conversion acquisition function, includes a key spectral analysis function, in time-interleaved acquisition systems to enable acquisitions at very high sample rates and bandwidths. Digital down-conversion allows data compression into acquisition memory for down-converted complex baseband I/Q data within a given frequency range of interest. With a fixed-size acquisition memory, this enables acquisitions over a longer time span, thus enabling a lower spectral resolution bandwidth. These approaches allow down-converted complex baseband I/Q data from a narrow frequency band of interest to be acquired efficiently. Reconstruction of the acquired down-converted waveform from the time-interleaved components stored in each acquisition memory of each distributed acquisition components to result in a coherent waveform is also disclosed.
