Automated Inspection Lowers Solar Cell Costs

The solar cell market is poised to experience exceptional growth, but continued success in the market will require manufacturers to drive production costs down. Automated optical inspection (AOI) using machine vision systems will play a key role in this cost reduction by speeding production and reducing waste. The challenge is to have the right vision system for each inspection task.

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.

Fundamentals of Vector Network Analysis Primer

One of the most common measuring tasks in RF engineering involves analysis of circuits (networks). A network analyzer is an instrument that is designed to handle this job with great precision and efficiency. Circuits that can be analyzed using network analyzers range from simple devices such as filters and amplifiers to complex modules used in communications satellites

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.
