High speed digital test and dynamic protocol reconfiguration
Design How-To 9/29/2011 1 comment
There are a variety of good tools on the market for debugging digital designs. Each has advantages and disadvantages that solve specific niche problems. No tool can solve all problems at all speeds and for all protocols. This paper provides a discussion of the relative merits and demerits of high speed digital test approaches and dynamic protocol reconfiguration.

More than half of the vehicle breakdowns that are caused by the electrical system can be traced back to the lead-acid battery and could have been avoided by knowledge of the battery state. A battery management system provides the necessary information by fast and reliable detection of the State-of-Charge, State-of-Health, and State-of-Function in terms of cranking capability.

Hunting noise sources in wireless embedded systems
Design How-To 9/14/2011 1 comment
In an embedded system design, especially one bringing together high-speed RF and serial or parallel components, noise can come from almost anywhere. Without clues as to the sources of noise, debugging can be time consuming and tedious. With a mixed domain oscilloscope (MDO) however, engineers can see noise sources like spectrum splatter during turn-on, drain voltage power supply coupling, or other cross-coupled emission events and correlate these events to specific logic states or analog circuit
Mobile measurement supports onboard EHV high-voltage testing
Design How-To 9/1/2011 Post a comment
On-road EHV testing calls for considerably greater data acquisition and wiring challenges than stationary applications. Onboard or road test data collection within a typical test track environment subjects instrumentation to higher-than-usual shock and vibration inputs, placing greater mechanical demands upon components and systems.
