Influencing Factors and Uncertainty in Measurements of Transmitting Radio Electronic Equipment Characteristics

In this paper we discuss the influencing factors and uncertainty in measurements of transmitting radio electronic equipment characteristics. We describe main internal and external factors affecting the functioning of radio-electronic equipment. In this paper, we pay special attention to the transmitting radio-electronic equipment, and the main internal and external factors affecting the characteristics and properties are considered. The impact on measurements uncertainty of radiation characteristics from radio-electronic equipment is covered in detail. The analysis of the influence of internal and external factors on the measurement results is carried out, and the results of the calculation of the uncertainty arising under the influence of typical influencing factors on the measuring device are given, taking into account of electromagnetic fields properties. The problems of choosing measuring instruments for measuring of electromagnetic fields characteristics are discussed.
