Smith charts were developed at a time when it was still difficult to directly measure the frequency
swept impedance of measurement objects. The Smith chart is used to determine the impedance at a
certain point of the reflection curve. To display the Smith chart of our quartz filter's impedance apply
the settings shown below to Trace 1:
After applying the settings a smith chart like the one shown below will be displayed:
