A detailed view of a high-performance red RF directional coupler bench test setup. The central red coupler is placed on a clean workbench, label-free. To the left is a coiled copper coaxial cable with BNC connectors. To the right is a small, separate label-retaining metal coupler. In the background, a large grey analyzer with small labels and blue text is to the left, and a multi-port analyzer with a full display showing a blue and yellow waveform is to the right. All other components, including BNC connections and text labels on the background analyzers, are present and visible.
