Mark Bieler, Paul Struszewski, Ari Feldman, Jeffrey Jargon, Paul D. Hale, Pengwei Gong, Wen Xie, Chuntao Yang, Zhigang Feng, Kejia Zhao, Zhijun Yang
We report on the first international comparison in ultrafast waveform metrology. To this end, the frequency and time responses of a photodiode with a nominal bandwidth of 100 GHz have been measured by several National Metrology Institutes during the last

Physical Models and Dimensional Traceability of WR15 Rectangular Waveguide Standards for Determining Systematic Uncertainties of Calibrated Scattering-Parameters

August 10, 2020
Author(s)
Jeffrey A. Jargon, Dylan F. Williams, Angela C. Stelson, Christian J. Long, Aaron M. Hagerstrom, Paul D. Hale, John R. Stoup, Eric S. Stanfield, Wei Ren
In this report, we document the models and dimensional traceability of our WR15 rectangular waveguide standards for performing multiline thru-reflect-line calibrations from 50 GHz to 75 GHz using vector network analyzers. We identify the equations used in

Channel Sounder Measurement Verification: Conducted Tests

April 15, 2020

Jeanne T. Quimby, Jeffrey A. Jargon, Rodney W. Leonhardt, Jake D. Rezac, Paul D. Hale, Catherine A. Remley, Amanda A. Koepke, Robert Johnk, chriss Hammerschmidt, Paul Mckenna, Irena Stange, Mike Chang
Channel modeling often provides a basis for the design and deployment of wireless technology. Engineers design systems to operate under certain expected channel conditions. Channel models are typically based on the statistics of a collection of many

Generalized source-conditions and uncertainty bounds for deconvolution problems

October 1, 2018
Author(s)
Jake D. Rezac, Andrew M. Dienstfrey, Nicholas A. Vlajic, Akobuije D. Chijioke, Paul D. Hale
Many problems in time-dependent metrology can be phrased mathematically as deconvolution problems. In such cases, measured data is modeled as the convolution of a known system response function with an unknown input signal, and the goal is to estimate the

Waveform metrology: Signal measurements in a modulated world

August 3, 2018
Author(s)
Paul D. Hale, Dylan F. Williams, Andrew M. Dienstfrey
In this work, we review the \full waveform metrology" concept that we introduced at the National Institute of Standards and Technology. Under this paradigm the full waveform and its functional representation is the target measurand. From the waveform

3.5 GHz Radar Waveform Capture at Fort Story

August 4, 2017
Author(s)
Paul D. Hale, Jeffrey A. Jargon, Peter J. Jeavons, Michael R. Souryal, Adam J. Wunderlich, Mark Lofquist
We describe measurements to create a library of high-fidelity waveforms of federal incumbent radar signals currently operating in the 3550 MHz – 3650 MHz (“3.5 GHz”) band. In this second phase of assembling the library, measurements were collected at Fort
