Why Skew-Matched Coaxial Cables Matter to Signal-Integrity Test and Measurement (.PDF Download)

March 17, 2020

Phase stability means reliable performance in specific test-and-measurement applications that call for a close match in frequency and phase between cables with low relative drift over temperature, vibration, and flexure. Yet, phase stability may not be adequate in cases where tighter skew tolerances are needed for a more synchronized distributed clock chain.

Skew-matched coaxial cables are specifically designed to service the growing data-rate demand in differential signaling applications. This article explores some common measurement parameters and how skew-matched coaxial assemblies can augment a test setup to lend more accuracy to the overall differential-signal characterization process.
