Electro-optic sampling for traceable high-speed electrical measurements

May 23, 2010
Author(s)
Paul D. Hale, Dylan F. Williams
We will describe how the complex frequency response of a high-speed photodiode is calibrated by use of electro-optic sampling. Our uncertainty analysis includes a unique covariance-matrix based method that allows us to transform uncertainties between the

Towards Standardized Waveguide Sizes and Interfaces for Submillimeter Wavelengths

March 22, 2010
Author(s)
Ronald A. Ginley, Dylan Williams, N M. Ridler, J L. Hesler, Anthony R. Kerr, R D. Pollard
This paper describes an activity that has begun recently to develop an international standard for rectangular metallic waveguides and their interfaces for frequencies of 110 GHz and above. The IEEE's Microwave Theory and Techniques Society (MTT-S) is

Interoperability Test of IEEE 1451.5 Standard-Based Wireless Sensors

March 13, 2010
Author(s)
Kang B. Lee, Yuyin Song
The Institute of Electrical and Electronics Engineers (IEEE) 1451 standard provides plug-and-play capability of smart transducers (sensors and actuators). Plug-and-play is an important aspect of interoperability, which is the ability of two or more systems

How Accurate is a Radio Controlled Clock?

March 1, 2010
Author(s)
Michael A. Lombardi
This paper discusses the factors that determine the accuracy of radio controlled clocks. The topics covered including the accuracy of the time signal station, path delay, synchronization errors, and the time error that accumulates between synchronizations.
