Pulse Patterns for the Josephson Arbitrary Waveform Synthesizer, CPEM 2024 abstract

Data provided by  National Institute of Standards and Technology

Delta-sigma algorithms are used to determine the desired sequence of quantum-based voltage pulses used by the Josephson Arbitrary Waveform Synthesizer (JAWS) to create calculable voltage waveforms. This data set contains a comparison (Fig 1. of the CPEM 2024 abstract) of a 1 kHz pulse pattern with rms amplitude of 2 mV without post-processing and with post-processing which modifies the problematic pulse pattern to remove incorrect pulses at the 0.75 ms pattern wrap point.

Traceable RF Power Metering Procedures With Thermoelectric Sensors.

Data provided by  National Institute of Standards and Technology

The National Institute of Standards and Technology (NIST) maintains the United States' primary standards for traceable RF and mm-wave power measurements. In the 2.4 mm connector type, the specialized sensors that NIST currently uses as primary standards are not commercially available, which raises concerns about the long-term sustainability of NIST's measurement capabilities. These concerns motivated us to explore the option of using commercially available thermoelectric power sensors.

High-SNR I/Q Recordings of FDD LTE User Equipment Emissions

Data provided by  National Institute of Standards and Technology

This dataset consists of high signal-to-noise ratio (SNR) in-phase and quadrature (I/Q) radio frequency (RF) recordings of long-term evolution (LTE) uplink emissions from a commercial-off-the-shelf (COTS) handset in a fully conducted environment. A base station emulator was used to configure the handset to statically transmit over various LTE physical resource block configurations for 1.4 MHz, 3 MHz, 5 MHz, and 10 MHz uplink channels centered at 1770 MHz in LTE Band 66, which is a frequency-division duplex (FDD) band.

ThermoData Engine free public version

Data provided by  National Institute of Standards and Technology

A computer program for accessing and visualization of thermodynamic and transport property data for chemical compounds and mixtures available at the TRC/NIST ThermoML archive https://data.nist.gov/od/id/mds2-2422. The data collection contains 2.2 million distinct property values (the whole archive can also be downloaded from that link, stored, and accessed from a local storage). The program has been compiled for Windows OS and tested under Windows 10. The operation procedures are described in the embedded Help.

Optical n(p, T_90) measurement suite 2: H_2O and D_2O

Data provided by  National Institute of Standards and Technology

Supplementary data for the article "Optical n(p, T_{90}) measurement suite 2: H_2O and D_2O" in International Journal of Thermophysics, by P.F Egan and Y. Yang.The supplementary material is an archive file of research data containing the n(p, T_{90}) datasets for ordinary water H_2O and heavy water D_2O measured at 633 nm wavelength. The data files also include uncorrected refractivity (raw data with the epsilon_phi error present). An included script operates on the uncorrected data and implements the analysis of App.

Hurricane Maria Wind-Field Model for Puerto Rico

Data provided by  National Institute of Standards and Technology

This data comprises the wind-field model for Hurricane Maria in Puerto Rico, which occurred in 2017. Wind speeds are reported as equivalent three-second peak gust wind speeds at 10 m height over open terrain (ASCE 7 Exposure C). Estimated peak gust speeds and associated wind directions are reported for two conditions: 1) assuming flat terrain, and 2) including topographic effects.
