Title:
Distributed taking-in device
Document Type and Number:
Japanese Patent JP6151483
Kind Code:
B2
Abstract:
A digital down-conversion acquisition function includes a key spectral analysis function in a time-interleaved acquisition system (200) to enable acquisitions at very high sample rates and bandwidths. Digital down-conversion (225) 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 (220) of each distributed acquisition component to result in a coherent waveform is also disclosed.
