Method for determining system error and power value for calibrating a network analyzer, calibration unit and system

摘要

To minimize connection trouble and measurement uncertainty in calibrating a network analyzer.Kind Code: A1 The invention relates to a method and system for determining system error and power values for calibration of a network analyzer with multiple test ports, in which short and Open calibration standard and power detector are sequentially connected, and the short and open calibration standards when each test port is stimulated with the stimulus signal and the response signal from the power detector are measured. Finally, a system error is obtained for each test port from the stimulus signal and the response signal. Finally, the power value of the stimulus signal in at least one test port is measured by a power detector connected to the test port.(FIG.
