Make impedance movement visible
A Smith chart helps turn complex reflection data into a visual tuning path.
- Plot S11 and S22 movement
- Inspect frequency markers
- Compare matching changes
- Keep Smith and rectangular plots connected
Smith chart
Smith chart inspection and RF matching
Use Smith chart views to inspect impedance trajectories, S-parameter behavior, return loss, matching targets, and component tuning effects.

RF measurements
Schematic
Capture, ports, labels, reusable sheets, and touch-friendly editing.
Plots
Waveforms, measurements, markers, RF traces, and tuning feedback.
RF
S-parameters, return loss, insertion loss, Smith chart, gain, and stability.
Tuner
Tune components and compare response changes without leaving the workspace.
Designed for tuning, not decoration
The Smith chart is part of the measurement workflow, not a standalone calculator isolated from the circuit.
- Start from the RF workspace
- Use target-frequency markers
- Tune component values
- Compare response changes
