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.
