Isbn: 9781390528244 - the nist 30/60 mhz tuned radiometer for noise temperature measurements (classic reprint) (1 risultati)

Paperback. Condizione: New. Print on Demand. This book is from 1997, and describes a radiometer for calibrating noise temperature at low frequencies, below about 1 GHz. It provides an overview of the radiometer system as it was put together during that time, including its theoretical background, experimental setup, and the uncertainty analysis for this system. A radiometer is a device designed to amplify and measure noise, which can then be used to infer the temperature of a system or device. The book discusses the various components of the radiometer system, including the preamplifier, filters, attenuators, and detectors, and how they are used to measure noise power. It also discusses the importance of matching the impedance of the radiometer to the impedance of the DUT (device under test) to minimize errors. The book provides a detailed analysis of the uncertainty of the system, taking into account factors such as mismatch errors, asymmetry errors, and nonlinearity effects. The book concludes by discussing the significance of the radiometer system for calibrating noise temperature at low frequencies, and its potential applications in various fields such as telecommunications and radar systems.
