- This graphics-intensive program reveals the load on the output of a matching-network, based on measurements of the components in that network. Adjust the network (tuner) for a flat input, measure or look up the network component values and you will immmediately see the R and jX values of the load on the network, presented as both a schematic with the component values and as a Smith Chart normalized to the specified system impedance.
