He concludes with an investigation of far-field sources. Before you measure the effects of design changes at your facility, say Briggs and Parker, take baseline emissions measurements. Minimize Power Loss in Test Racks Test stands sometimes can supply over 100 A of DC to one or several UUTs. To deliver that much current, power-distribution networks comprise power supplies, wires, connectors, switches, and perhaps bus bars and custom boards. Any part of that network can degrade a system s power delivery.
Careful design can minimize voltage drops and noise.
When you specify an optical time-domain reflectometer for field use, pay particular attention to test times, dynamic range, and resolution. Feucht shines new light on motor theory, based on frames of reference. Author David Morrison brings us up to date on what's happening in the world of oscillators. The Bode plot describes the requirements that an open-loop system must exhibit to be stable once the loop is closed. ChipCenter columnist Frank Greenhalgh offers an entertaining 'quickie' update on Bode plot essentials.
