Millimeter-Wave Channel-Sounder Performance Verification Using Vector Network Analyzer in a Controlled RF Channel

Abstract

A new comparison-to-reference performance verification technique compares an ${E}$ -band channel-sounder (CS) and reference vector network analyzer (VNA) measurements of the same controlled, static channel. This new technique reduces the number of inaccurate assumptions that exist in other methods providing a stronger verification of the CS hardware and processing performance. This technique compares the CS and VNA-derived channel metrics from these measurements. Using mechanical switches, we established a controlled, static RF channel. The VNA has a comprehensive uncertainty analysis that propagates systematic and random uncertainties through to the power delay profiles. The method is suitable for millimeter-wave CS hardware with removable antennas.
