Propagating Measurement Uncertainty to Microwave Amplifier Nonlinear Behavioral Models

February 1, 2019
Author(s)
Dylan F. Williams, Laurence T. Stant, Martin J. Salter, Nick M. Ridler, Peter Aaen
We propagate for the first time correlated measurement uncertainties into a nonlinear behavioral model of a millimetre-wave amplifier. We make use of the NIST Microwave Uncertainty Framework to evaluate the uncertainties in large-signal electromagnetic

3.5 GHz Federal Incumbent Protection Algorithms

October 21, 2018
Author(s)
Michael R. Souryal, Thao T. Nguyen, Nickolas J. LaSorte
The current standardized algorithm for U.S. federal incumbent protection in the 3.5 GHz band is sub-optimum in that it moves more commercial transmissions out of the protected channel than necessary, in most cases. This paper proposes a more efficient

STEP File Analyzer User's Guide (Version 3)

April 27, 2016
Author(s)
Robert R. Lipman
This guide describes how to use the STEP File Analyzer, a software tool that analyzes and generates a spreadsheet from a STEP (STandard for the Exchange of Product model data) file. The spreadsheets simplify inspecting information in the STEP file at an

EUV spectra from N-shell ions of Gd, Dy and W

September 23, 2013

Deirdre Kilbane, John D. Gillaspy, Yuri Ralchenko, Joseph Reader, G. O'Sullivan
… open n=4 shell were performed at the National Institute of Standards and Technology. The ions were produced and confined …

Interference Tests for 900 MHz Frequency-Hopping Public-Safety Wireless Devices

August 15, 2011
Author(s)
Catherine A. Remley, Michael R. Souryal, William F. Young, Daniel G. Kuester, David R. Novotny, Jeffrey R. Guerrieri
We discuss free-field measurement methods designed to quantify interference between wireless devices such as RF identification systems and RF-based emergency beacons used by fire fighters. For public safety applications, standardized testing is important

Coordinating GPS Calibrations Among NIST, NRL, USNO, PTB, and OP

July 31, 2011
Author(s)
Marc A. Weiss, Victor S. Zhang, J White, K Senior, Demetrios Matsakis, S. Mitchell, P Uhrich, D Valat, W Lewandowski, G. Petit, Andreas Bauch, T. Feldman, A. Proia
Reviewing calibration results over the history since early 1980’s among several labs shows very mixed results. The best stabilities of receivers, as given by calibrations, are of the order of a few ns or better over a year, though many results are quite a

System Builders Manual for Version 2.2.1 of the NIST DMIS Test Suite

October 25, 2010
Author(s)
Thomas R. Kramer, John A. Horst
This manual is a system builders manual for the NIST DMIS Test Suite, version 2.2.1. DMIS (Dimensional Measuring Interface Standard) is a language for writing programs for coordinate measuring machines and other dimensional measurement equipment. The

Half-life Measurements of Sr82

January 30, 2009

Leticia S. Pibida, Ryan P. Fitzgerald, Michael P. Unterweger, Michelle M. Hammond, Daniel B. Golas
… of 82Sr were performed at the National Institute of Standards and Technology (NIST) using gamma-ray spectrometry …

Polarization-Locked Temporal Vector Solitons

October 16, 2008
Author(s)
Steven T. Cundiff, B C. Collins, N N. Akhmediev, J M. Soto-Crespo, K Bergman, W H. Knox
Solitons are the subject of substantial research because of potential applications in high-speed fiber-optics communications. However, discussions of soliton propagation often ignore polarization and use scaler equations to describe their evolution

Long Term Sustainment Workshop Report

Joshua Lubell, Mahesh Mani, Eswaran Subrahmanian, Sudarsan Rachuri
… of a workshop held at the National Institute of Standards and Technology (NIST) on April 24-25, 2007. The …

Physical and Chemical Data, Section 2

November 13, 2007
Author(s)
Daniel G. Friend, Bruce E. Poling, George H. Thomson, Thomas E. Daubert, Evan Buck
This Section provides tabular material for the physical and chemical properties of substances of interest to the chemical engineering community. Many of the tables have been generated using NIST standard reference data formulations, which provide

CVSS-SIG Version 2 History

July 30, 2007
Author(s)
Peter M. Mell, Karen A. Scarfone, Gavin Reid
This document attempts to interpret the history and rationale behind changes made in the Common Vulnerability Scoring System (CVSS) from version 1 to version 2 (referred to as CVSS v1 and v2 in this document.) This document contains multiple appendices

Experimental Vibrational Zero-Point Energies: Diatomic Molecules

April 18, 2007
Author(s)
Karl K. Irikura
Vibrational zero-point energies (ZPEs), as determined from published spectroscopic constants, are derived for 85 diatomic molecules. Standard uncertainties are also provided, including estimated contributions from bias as well as the statistical

PARCS: NASAs Laser-Cooled Atomic clock in Space

December 1, 2005
Author(s)
Donald Sullivan, Neil Ashby, Elizabeth A. Donley, Thomas P. Heavner, Leo W. Hollberg, Steven R. Jefferts, William Klipstein, David Seidel, D. J. Phillips
The PARCS (Primary Atomic Reference Clock in Space) mission is designed, not only to perform certain tests of relativity theory, but also to demonstrate space-clock technology that may prove useful as an international standard of frequency and time and for
