Analyzer Calibration for Reflection Coefficient Measurement

Calibration of the whole measurement setup—which includes the Analyzer, cables and other devices involved with connection to the DUT—allows for considerably enhancing the accuracy of the measurement.

To perform full 1-port calibration, you need to prepare the kit of calibration standards: OPEN, SHORT and LOAD. Such a kit has its description and specifications of the standards. To perform proper calibration, you need to select the correct kit type in the program.

To perform the process of full 1-port calibration, connect calibration standards to the test port one after another, as shown in Figure 16.

Figure 16 Full 1-port calibration circuit

In the current example, an Agilent 85032E calibration kit is used.

To select the calibration kit, use Calibration menu item and select Calibration Kit.

To perform full 1-port calibration, you will execute measurements of the three standards in turn. After completion, the table of calibration coefficients will be calculated and saved into the memory of the Analyzer. Before you start calibration, disconnect the DUT from the Analyzer.

To perform full 1-port calibration, use the Full 1-Port softkey in the Calibration menu.
