    User: Scan my antenna from 144 to 148 MHz with 201 points

    Claude uses: sweep(144000000, 148000000, 201)
    Claude uses: scan(s11=true)
    Claude uses: analyze()
    ```
  </TabItem>
  <TabItem label="Filter Analysis">
    ```
    User: Analyze this bandpass filter from 1 to 500 MHz

    Claude uses: sweep(1000000, 500000000, 201)
    Claude uses: analyze_filter()
    ```
  </TabItem>
  <TabItem label="Calibration">
