Figure 3.2.32: Smith Chart
Smith Chart
See Figure 3.2.32 . The Smith Chart allows you to visualize the impedance of the transmitter’s load as
seen at the combiner, as a function of frequency. The impedance shown on the Smith Chart is
normalized to the combiner input impedance. The ideal load is therefore 1 +j0 ohms, which implies a
perfect 50-ohm load is being applied to the output of the transmitter.
Click on the panel to display a cursor in the nearest area on the trace showing the normalized
impedance plot line. The cursor position (impedance and frequency) is noted in the upper, right-hand
corner of the panel. Click in other areas of the instrument panel to provide a coarse adjustment of the
cursor position.
Use the left and right buttons as fine adjustments to the cursor position.
Use the zoom in (+) and zoom out (-) buttons to size the chart between 100% and 1000%.
Use the up or down button to maximize (if it was minimized) or minimize (if it was maximized) the
panel size.
