Building a Test System for High-Speed Data Streaming Applications

High-speed data streaming applications typically require maximum accuracy and long sampling times, including such applications as spectral monitoring, signal intelligence, LIDAR testing, optical fiber testing, radar and satellite signal acquisition, and software defined radio systems. These present unique engineering challenges requiring high throughput, and identifying design flaws and problems can contribute to reduced development costs and time to market, avoiding field recalls and costly system redesigns. The white paper discusses techniques for optimizing configuration of systems supporting high-bandwidth applications, by: Enabling high-speed real-time data streaming Designing applications optimizing system streaming performance Furnishing benchmarks that can be achieved in stream-to-disk and stream-to-memory applications

Accurate Finite Element Simulation of Conductors

Simulation of electromagnetic systems relies on the accurate and efficient representation of electrical conductors and coils. This whitepaper reviews the ways conductors can be represented using the industry leading Opera Simulation Software Suite from Cobham. The methods explored include various bulk approximations useful for multi-turn windings as well as explicit methods to include current redistribution due to proximity, geometry and skin effects.

Oscilloscope Fundamentals Primer

The oscilloscope is arguably one of the most useful tools ever created for use by electronic engineers. In the more than five decades since the modern analog oscilloscope was created, hundreds of useful documents and thousands of articles have been written about what it is, how it works, how to use it, and application-specific examples of the “oscilloscope” in action. It is the purpose of this primer to instead describe digital oscilloscopes, which have for practical purposes replaced their analog predecessors in the vast majority of applications. Covered here is a short description of the oscilloscope’s origins, its transition from analog to digital, types of digital oscilloscopes and their major subsystems, key benchmark specifications, and measurements.

Magnetics Design: Specification, Performance & Economics

An informative white paper from Datatronics Romoland, Inc., provides a discussion of the design, development and delivery of affordable magnetic components. The design development process begins once performance requirements are specified. Upon design approval, the procurement of materials for a prototype build is initiated. During this stage, specifications are not final and options remain open for cost-effective production. Specifications must be reviewed and design trade-offs evaluated to ensure that the technical requirements are economically attainable with consideration given to performance and tolerance in relation to affordable cost.

An Introduction to LED Capabilities

Developments in LED technology have created an even wider range of new applications. The LED industry is booming in part due to the introduction of high intensity blue LEDs and the use of white LEDs in aerospace and lighting engineering. Increased capability and application also creates increased demands on optical characterization of LEDs. In order to meet this increased demand for a reliable, high quality product, special technological capability is necessary in order to maintain precise results that can be reproduced. The purposes of this white paper are to provide an overview of the terms used in LED testing and development for LED metrology newcomers and experienced professionals alike. Additionally, it will provide a comparison of the equipment used in the LED industry as well as recommendations for applications and obtaining accurate measurement results.
