摘要： Disclosed is a method of processing an S-parameter to analyze transient phenomena in a passive network, the method including: generating an extrapolation function related to a real part of a measured S-parameter signal; generating an expanded S-parameter signal by the extrapolation function; and setting an optimum degree and an optimum expansion frequency of the expanded S-parameter signal. Thus, the extrapolation function where continuity from the real part of the measured S-parameter signal is ensured is used such that causality in an impulse response of the expanded S-parameter signal can be maintained without problems.

摘要： Embodiments of this invention include a test and measurement instrument and associated methods for acquiring and stitching wide overlapped non-uniform frequency bands so that a user specified band can be efficiently displayed and analyzed. The test and measurement instrument includes a user interface to receive the user specified frequency span. Acquisition circuitry acquires one or more predefined frequency bands having non-uniform overlapping frequency ranges. A frequency band processing section can decimate the acquired frequency bands, mask the acquired frequency bands, and stitch the masked frequency bands together. A display section displays the user specified frequency span using the stitched frequency bands. Due to the overlap configuration of the wide non-uniform bands, any user specified span between 50 kHz and 6 GHz, or thereabout, can be covered by two bands.

摘要： Various embodiments herein include one or more of systems, methods, software, and/or data structures to extract models of components (e.g., vias and traces) for PCB channels from measurements (or simulations) taken from physical PCB channels. By applying stochastic optimization to measurements of two PCB channels having different channel lengths, s-matrices (e.g., two-port, four-port, and the like) of the components of a PCB channel may be accurately determined by searching the multi-dimensional parameter space for parameters that comply with the measured values. Once the models for the components have been accurately determined, they may be utilized in constructing a model library that includes component models and is based on physical measurement data.

摘要： A system and technique for providing to flexible, programmable frequency estimators and spectrum analyzers that can operate over extremely large bandwidths and yet provide high spectral resolution are described. The acquisition time and hardware complexity of one technique scale as O(N), where N denotes the number of frequency bins acquired.
