Displaying Smith Charts

The input impedance as a function of frequency can be plotted in a Smith chart by clicking the Smith button in the Input List > dialog box. Follow the procedure described in Listing the Input Impedances > for listing the input impedances versus frequency, and then click the Smith button in the opened dialog box.

Left click on the impedance curve in the Smith chart to see the frequency, input impedance (Zin), reflection coefficient (Rho) and VSWR in a hint message, Fig 1. Go to the AN-Smith main menu > Plot > Admittance to plot the input admittance curve. Go to Edit > Preferences to change the visualization options in AN-Smith.
