RF WORKBENCH

Smith chart

Explore impedance, admittance and reflection. Reference impedance: Z₀ = 50 Ω.

Scroll to zoom · drag to pan · drag a marker with a mouse or touch. Tab to a marker; use arrow keys to move it, Shift+Arrow for ten samples, Home/End for endpoints. Grid values are normalized to Z₀.

Parameter scales

Save the current view for a report. Colors and label detail follow the chart's current settings. Use the Light theme for a white report background.

Leave one dimension empty to preserve proportions. With both dimensions set, the image fits without cropping. Maximum: 8192 px per side and 32 megapixels.
