Cable and Antenna Analyzer for Anritsu’s RF and Microwave Handheld Instruments : Cable and Antenna Analyzer : Smith Chart
  
Smith Chart
1-port measurements can be displayed in a standard normalized 50Ω Smith Chart. When markers are used, the real and imaginary components of the Smith Chart value are displayed.
Anritsu Line Sweep Tools includes more options and a calculator that can easily show what the return loss, VSWR, or reflection coefficient values of a specific Smith Chart value.
Limit Lines in a Smith Chart will appear as circles (constant reflection coefficient) and can be entered in VSWR units.
