Latest Patents

Ammerman holds a patent for a "Spectral stitching method to increase instantaneous bandwidth in vector signal analyzers." This invention describes various embodiments of devices and associated methods for processing a signal using multiple vector signal analyzers (VSAs). The method involves splitting an input signal and providing it to several VSAs, each processing a specific frequency band of the signal, with overlapping regions. Each VSA adjusts the gain and phase of its respective signal to maintain continuity of phase and magnitude through these overlapping regions. The correction of gain and phase is achieved through a complex multiply with a complex calibration constant, which is determined by comparing the gain and phase of calibration tones generated within the overlapping regions.
