In this paper, the necessity of amplitude calibration for microwave and mil imeter wave signal analyzer is analyzed. Starting with the basic principle of signal analyzer, the source of amplitude measurement error is analyzed. The calibration methods of attenuator, frequency response, resolution bandwidth and other errors using internal and external calibration sources are introduced. Finally, the technical specifications of signal analyzer based on this calibration method are given, the validity of error source analysis and calibration is proved.
