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()

Filter Analysis

User: Analyze this bandpass filter from 1 to 500 MHz

Claude uses: sweep(1000000, 500000000, 201)
Claude uses: analyze_filter()

Calibration

User: Calibrate for the 2m band

Claude uses: sweep(144000000, 148000000, 101)
Claude uses: cal("load")   # user connects load
Claude uses: cal("open")   # user connects open
Claude uses: cal("short")  # user connects short
Claude uses: cal("thru")   # user connects through
Claude uses: cal("done")
Claude uses: save(0)
