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.

워크벤치 활용 가이드
이 페이지는 측정 데이터 리뷰 콘솔로 쓰는 것이 가장 효율적입니다. 데이터를 붙여넣고, Smith 궤적을 확인하고, 세트 간 비교와 스펙 판정을 한 화면에서 처리하세요.
- Blank line 세트 분리를 이용해 온도/로트/치구 조건을 구분해 관리하세요.
- Sweep, Spec 기능을 함께 켜서 추세와 임계치 통과 여부를 동시에 확인하세요.
- 표/차트 내보내기로 리뷰 근거를 문서화하세요.
