Identification of Admittance point, when load point is known.Representation of short-circuit and open-circuit points on Smith chart.Understanding the meaning of intersection of resistance and reactance circle over smith chart.Identification of resistance, reactance and VSWR circles on Smith chart.Realization of Smith chart and the basics of drawing a Smith chart.From this experiment we will learn to use the Smith chart for transmission-line calculations.This experiment will be helpful in learning following topics: 1) as a graph-based method of simplifying the complex math (that is, calculations involving variables of the form x + jy) needed to describe the characteristics of microwave components. The following figure shows the Smith Chart interface with a chart that is overlaid by a constant 1.5:1 SWR circle. AAplot can either plot the measure value as impedance components (resistance and reactance) or as admittance components (conductance and susceptance). This experiment gives an introduction to Smith chart and its application for the unknown impedance measurement. A Smith Chart maps the entire right half of a complex plane into a finite circle.

The center of the circle is the center of the chart. Here Smith chart has been designed using LabVIEW programming for better understanding the concept behind smith chart using graphical user interface. Smith Chart Thus, the first step in analyzing a transmission line is to locate the normalized load impedance on the chart Next, a circle is drawn that represents the reflection coefficient or SWR.

The best known and most widely used graphical chart is the Smith chart devised by P.H. This tedium can be alleviated by using a graphical method of solution. Transmission-line calculation - such as determination of input impedance, reflection coefficient and load impedance, involve tedious manipulation of complex numbers.
