NIST open new special test measurement service for 2.92 mm coaxial power detectors. (News Briefs).Staff at NIST (National Institute of Standards & Technology, Washington, DC, www.nist.gov) The standards-defining agency of the U.S. government, formerly the National Bureau of Standards. It is one of three agencies that fall under the Technology Administration (www.technology. recently opened a new Special Test Service for 2.92 mm coaxial power detectors. This new service measures the effective efficiency and calibration factor of thermistor Thermistor An electrical resistor with a relatively large negative temperature coefficient of resistance. Thermistors are useful for measuring temperature and gas flow or wind velocity. , thin-film, and thermoelectric power Thermoelectric power can refer to two things:
In recent years, the Years, The the seven decades of Eleanor Pargiter’s life. [Br. Lit.: Benét, 1109] See : Time instrument manufacturers have been moving to coaxial line sizes that operate at frequencies up to 40 GHz and beyond. A number of electronic instruments are now commercially available that have 2.92 mm coaxial connectors and that operate at frequencies up to 40 GHz. The new service will provide power measurement traceability for those devices. The power calibrations are made on the NIST direct comparison system. This system is calibrated cal·i·brate tr.v. cal·i·brat·ed, cal·i·brat·ing, cal·i·brates 1. To check, adjust, or determine by comparison with a standard (the graduations of a quantitative measuring instrument): using 2.4 mm thin-film detectors, and characterized 2.4/ 2.92 mm adapters. The new service was developed in cooperation with the Air Force, Army, and Navy Primary Standards Laboratories. CONTACT: John Juroshek, (301) 975-5362; john.juroshek@nist.gov. |
