When measuring coaxial cables using a network analyzer, it’s crucial to understand that the displayed adjustment (or return loss) results from the superposition of reflected signals from both connectors. One unit you’ll encounter frequently in this context is the decibel (dB). But what exactly is a decibel, and how...

Selecting the optimal RF measurement cable is not a matter of luck but of informed decision-making. Each cable must meet a specific combination of performance, durability, and environmental tolerance. Measurement engineer Stefan Burger, founder of Delta Gamma RF-Expert in Australia, shared critical insights on how to ask the right...

In high-frequency engineering, one of the fundamental parameters used to assess component and system performance is return loss. This metric reflects how well the connections are matched, directly affecting signal reflection and transmission quality. A Vector Network Analyzer (VNA) is the primary tool for this analysis, capable of displaying...
