Abstract:
Embodiments are described of devices and methods for processing a signal using a plurality of vector signal generators (VSGs). A digital signal may be provided to a plurality of signal paths, each of which may process a respective frequency band of the signal, the respective frequency bands having regions of overlap. The gain and phase of each signal path may be adjusted such that continuity of phase and magnitude are preserved through the regions of overlap. The adjustment of gain and phase may be accomplished by a complex multiply with a complex calibration constant. The calibration constant may be determined for each signal path by comparing the gain and phase of one or more calibration tones generated within each region of overlap. Each signal path may comprise a VSG to convert the respective signal to an analog signal, which may be combined to obtain a composite signal.

Claim (Index 14):
An apparatus for processing a digital signal, the apparatus comprising:\n a first signal processing pathway configured to:\n receive a first component signal comprising a first frequency band of the digital signal; and \n convert at least the first frequency band to a first analog signal; \n a second signal processing pathway configured to:\n receive a second component signal phase-locked with the first component signal, the second component signal comprising a second frequency band of the digital signal, the second frequency band having a region of overlap with the first frequency band; and \n convert at least the second frequency band to a second analog signal; \n a signal combiner configured to combine the first analog signal and the second analog signal to obtain a composite signal; a calibration receiver configured to, while the apparatus is in a calibration mode, compute a calibration constant useable to correct phase mismatch between the first signal processing pathway and the second signal processing pathway, wherein the calibration constant is computed based on a phase difference between a first version of a calibration tone output by the signal combiner while the first signal processing pathway is disabled, and a second version of the calibration tone output by the signal combiner while the second signal processing pathway is disabled, wherein the calibration tone is included in the digital signal within the region of overlap between the first frequency band and the second frequency band; and a memory configured to store the calibration constant.
