Digital Diagnostics: The Key to System Performance

Roy H. Trumbull

Digital devices used for captioning, switching, video effects, and automation have enhanced the capabilities of TV stations and production houses. However, a typical system doesn't have the ability to trace faults to a single circuit board, let alone attribute the fault to the defective circuit. Presently, systems are repaired by swapping circuit boards with the manufacturer, and downtime is measured in days or weeks. Simple, cost-effective diagnostics can be built into any system. This article presents an overview of the problem and advocates the adoption of Signature Analysis (SA) as the diagnostic method of choice.
