The Analyzer supports several methods of one-port and two-port calibration. The calibration methods vary by quantity and type of the standards being used, by type of error correction, and accuracy. The calibration kit is selected according to the selected calibration method. It is possible to select a calibration method from the available calibration kits. The calibration kit is selected before starting calibration (See Calibration Kit Selection). The table below presents an overview of calibration methods.

note |
In the waveguide path, the SOL (Short-Open-Load) calibration method can be replaced by the SSL (Short-Short-Load) and SSS (Short-Short-Short) methods. In these methods, the OPEN and LOAD standards are replaced by SHORT standards with different offsets by assigning them the corresponding classes. Both of these methods are also applicable to the coaxial path. For more details, see SSL and SSS Calibration. |
