NIST has delivered a portable and highly accurate instrument for measuring mass to the U.S. Army, marking the first time in the U.S. that this technology is
Perched atop a high plateau in Chile’s Atacama Desert, a long-awaited observatory is beginning to take shape: the largest suite of ground-based telescopes
Physicist Jun Ye has a knack for making every second count—literally. At JILA, a joint research institute of the University of Colorado and the National
We have a number of opportunities to collaborate with us. See below for details. What does this project aim to do for the chemical industry? Many industrial processes depend on the intermolecular environment- the solvents and ions that surround a molecule. These interactions impact separations
NIST calibrates electrically-small field probes from 10 megahertz – 40 gigahertz. These measurements are done in facilities that are periodically compared against other National Metrology Institutes in conjunction with the Bureau International des Poids et Mesures (BIPM). This assures international
The science of microwave measurements is expanding in many different directions. There is a constant push to use higher frequencies. Signals are becoming much more complex and include modulation effects, multiport/differential signals, complex waveforms, and other unusual signal schemes. On-wafer
Quantum-Based Reference Sources The demand for wireless communications has exploded over the last 2 decades and there is no end in sight. The quest for higher bandwidth is driving the use of higher carrier frequencies in the microwave and millimeter-wave (>30 GHz) bands. However, there are no

Standard formulations of error vector magnitude compare a wireless device's symbol constellation to an ideal reference constellation. In this work, we utilize
NIST Microwave Uncertainty Framework (Beta version) The NIST Microwave Uncertainty Framework provides a "drag-and-drop" toolkit for managing the calculation of
The Large Aperture Scanner (LAS) scans a radar transceiver over a 5 meter by 20 meter aperture. Image reconstruction techniques enable a three-dimensional
