Load — Fixed Z, Z(f) table, or S-param from .s2p files.
Smith — Match at design F. Legend under chart. VSWR / Q on toolbar.
Network — Edit on schematic (click / scroll / ×). Build snaps L/C/R to stock values for the set tolerances (⚙); Auto-tune optimizes continuous values at design F.
Frequency response — Toggle Matched S₁₁ and Raw S₁₁ (no network → they match). RL guide draws the RL ≥ line and shades pass bands. ⚙ Limits sets Design-at-F and band slider min/max.
Save / Load — full project including S-param library.
