Implementing frequency spectrum analysis using causality Hilbert Transform results of VNA-generated S-parameter model information

摘要

A method, system and computer program product are provided for implementing frequency spectrum analysis of noise in a device under test using causality (Hilbert Transform) results of Vector Network Analyzer (VNA) VNA-generated S-parameter model Information. A plurality of S-parameter samples are collected from the VNA generated S-parameter model Information. A Hilbert Transform of the collected plurality of S-parameter samples is used for error magnitude per frequency point analysis. An average error magnitude of predefined collected error magnitude samples is calculated to identify environmental noise in the device under test and used to identify acceptable environmental effects on the device under test.
