Download or read book A Note on Noise Factor Measurement written by Wave Propagation Laboratory and published by . This book was released on 1969 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definition of noise factor, F, is reviewed and the mathematical bases for several methods of measuring noise factor are presented. Error analyses are given to determine: (1) the noise source temperatures, which minimize the noise factor measurement error, (2) an analytic expression for the expected error in F as measured by the CW methods, and (3) an analytic expression for the expected error in F as measured by the Y-Factor Method. A hypothetical receiver (of assumed characteristics) is used as a comparative example to elevate the errors to be expected in F as measured by the CW Method and by the Y-Factor Method. The importance of bandwidth as a criterion of receiver performance is stressed. The effect on the measured F produced by a change in receiver gain-bandwidth produced by a change in received gain-bandwidth produced by a change is receiver gain-bandwidth produce is considered briefly. A preliminary calculation of the source temperatures actually seen by the receiver input completes the report. The appendix is a procedural outline for measuring a receiver's noise factor by: (1) automatic noise factor meter (ANFM), (2) CW Method, and (3) Y-Factor Methods. This outline indicates the characteristics required of the test equipment and tells how to obtain the necessary data.

Available in PDF, EPUB and Kindle. Book excerpt: The metrology guide provides the basis for critical comparisons among seven measurement techniques for average noise factor and effective input noise temperature. The techniques that are described, discussed, and analyzed include the (1) Y-Factor, (2) 3-dB, (3) Automatic, (4) Gain Control, (5) CW, (6) Tangential, and (7) Cmparison Techniques. The analyses yield working equations and error equations by which accuracy capabilities are compared. Each technique is also analyzed for (a) frequency range for best measurement results, (b) special instrumentation requirements, (c) speed and convenience, (d) operator skill required, and (e) special measurement problems. General instrumentation requirements and practical measurement problems are discussed for the benefit of the non-expert metrologist. (Modified author abstract).

Download or read book Handbook of Microwave Component Measurements written by Joel P. Dunsmore and published by John Wiley & Sons. This book was released on 2020-06-29 with total page 852 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Microwave Component Measurements Second Edition is a fully updated, complete reference to this topic, focusing on the modern measurement tools, such as a Vector Network Analyzer (VNA), gathering in one place all the concepts, formulas, and best practices of measurement science. It includes basic concepts in each chapter as well as appendices which provide all the detail needed to understand the science behind microwave measurements. The book offers an insight into the best practices for ascertaining the true nature of the device-under-test (DUT), optimizing the time to setup and measure, and to the greatest extent possible, remove the effects of the measuring equipment from that result. Furthermore, the author writes with a simplicity that is easily accessible to the student or new engineer, yet is thorough enough to provide details of measurement science for even the most advanced applications and researchers. This welcome new edition brings forward the most modern techniques used in industry today, and recognizes that more new techniques have developed since the first edition published in 2012. Whilst still focusing on the VNA, these techniques are also compatible with other vendor's advanced equipment, providing a comprehensive industry reference.

Available in PDF, EPUB and Kindle. Book excerpt: Written by prominent experts in the field, this authoritative new resource provides guidelines for performing a wide variety of Vector Network Analyzers (VNA) measurements. The capabilities and limitations of modern VNA in the context of challenging real-world applications are explained, as well as insights for optimizing test setups and instrument settings, making accurate measurements and, equally important, avoiding costly mistakes. Organized by topic, the readers can focus on chapters covering particular measurement challenges. Application topics include linear and non-linear measurements of passive and active devices, frequency converting devices, and special considerations for high-power, high-gain, and pulsed devices. Signal Integrity and time-domain reflectometry are covered, as well as emerging applications at millimeter-wave frequencies driven by 5G and automotive radar. Waveguide is presented, with emphasis on understanding guided-wave propagation and the associated calculations required for creating calibration standards. Each application is supported by illustrations that help explain key concepts and VNA screenshots are used to show both expected and, in some cases, unexpected results. This book equips engineers and lab technicians to better understand these important instruments, and effectively use them to develop the technologies that drive our world.
