Smith Chart Workbench
Excel paste + frequency sweep + de-embedding + pass/fail mask + matching synthesis.
Input and RF Controls
Apply current tab settings to chart immediately.
How to use this tab
- Paste data into the input box. Use blank lines to split sets.
- Select set color/display options and enable markers, value text, or coordinate text.
- Click Draw/Refresh to apply changes and update summary/table/chart.
Delimiter: comma/tab/space. Blank line = new set. In sweep mode use 3 columns (freq, A, B) or 2 columns with auto sweep start/stop.

Actions
Ready.
How to use this tab
- Turn on frequency sweep and set the frequency unit.
- Use either 3-column input (frequency, A, B) or 2-column input with start/stop frequency.
- Use Draw/Refresh to enable sweep navigator and band summary.
Sweep Mode
If frequency column is omitted, points are spaced linearly between sweep start and stop.
Point count is limited to avoid overly dense rendering.
How to use this tab
- Enable de-embedding and choose shift direction (toward source/load).
- Set two-way phase and attenuation values.
- Optionally enable frequency scaling and run Draw/Refresh.
Reference Plane Shift (De-Embedding)
How to use this tab
- Enable mask check and set RL, VSWR, |Gamma|, and delivered power limits.
- Optionally highlight fail points directly on the chart.
- Run Draw/Refresh to update PASS/FAIL yield in real time.
Spec Pass / Fail
Spec check disabled.
How to use this tab
- Enable matching path and set design frequency.
- Choose up to 3 matching steps with component type and value.
- Draw/Refresh to see matching trajectory and final metrics.
Matching Synthesis (Focused Point)
Matching synthesis disabled.

How to Use This Workbench Efficiently
Use this page as a measurement review console: paste data, inspect Smith trajectory, compare sets, and validate pass/fail conditions in one place. This section was added to keep non-English routes aligned with the same engineering guidance available on the English route.
- Group points by fixture, lot, or temperature using blank-line set separation.
- Enable sweep and spec options to evaluate both trend and threshold pass/fail.
- Use the table export path to keep traceable review records.
