Cable and Antenna Analyzer Measurement Guide : 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.
Smith Chart Measurement
The following example shows how a Smith Chart can be used to measure the match of an antenna.
Procedure
1. Press the Measurement main menu key.
2. Press the Smith Chart submenu key.
3. Press the Freq/Dist main menu key and set the Start Frequency and Stop Frequency.
4. Press the Start Cal submenu key and perform a 1-port calibration. See 1-Port Calibration Procedure (OSL).
5. Connect the antenna to the RF Out connector on the BTS Master.
