Agilent Fundamentals of RF and Microwave Power Measurements (Part 3) Power Measurement Uncertainty per International Guides For user convenience, Agilent's Fundamentals of RF and Microwave Power Fundamentals of RF and Microwave Power Measurements, application Measurements (Part 1) note 64-1, literature number Introduction to Power, History, Definitions, International 5965-6330E, has been updated and Standards, and Traceability segmented into four technical subject AN 1449-1, literature number 5988-9213EN groupings. The following abstracts explain how the total field of power Part 1 introduces the historical basis for power measurements, and provides measurement fundamentals is now definitions for average, peak, and complex modulations. This application note presented. overviews various sensor technologies needed for the diversity of test signals. It describes the hierarchy of international power traceability, yielding comparison to national standards at worldwide National Measurement Institutes (NMIs) like the U.S. National Institute of Standards and Technology. Finally, the theory and practice of power sensor comparison procedures are examined with regard to transferring calibration factors and uncertainties. A glossary is included which serves all four parts. Fundamentals of RF and Microwave Power Measurements (Part 2) Power Sensors and Instrumentation AN 1449-2, literature number 5988-9214EN Part 2 presents all the viable sensor technologies required to exploit the users' wide range of unknown modulations and signals under test. It explains the sensor technologies, and how they came to be to meet certain measurement needs. Sensor choices range from the venerable thermistor to the innovative thermocouple to more recent improvements in diode sensors. In particular, clever variations of diode combinations are presented, which achieve ultra-wide dynamic range and square-law detection for complex modulations. New instrumentation technologies, which are underpinned with powerful
