(In the procedure below, the selected test ports are denoted as x and y.)Ĭonnect an OPEN calibration standard to test port x (the connector to which the DUT is to be connected).Ĭlick Port x Open to start the calibration measurement ( x denotes the test port to which the standard is connected). Press Channel Next/ Channel Prev keys to select the channel for which you want to perform the calibration.Ĭlick Select Ports, then select the test ports on which you will perform full 2-port calibration. ![]() System Z0 should be changed to 1 ohm before calibration when using waveguide calibration kit and measuring waveguide devices. A total of twelve error terms, six each in the forward direction and the reverse direction, are used in a calibration. This calibration makes it possible to perform measurements with the highest possible accuracy. In full 2-port calibration, calibration data are measured by connecting an OPEN standard, a SHORT standard, or a LOAD standard to two desired test ports (or a THRU standard between two ports).This calibration effectively eliminates the directivity error, crosstalk, source match error, frequency response reflection tracking error, and frequency response transmission tracking error from the test setup in a transmission or reflection test using those ports.
