Diagnostics for a Microprocessor-Based Videotape Recorder

M. Glen Rose, Gary Warren

With the evolutionary increase in complexity of control systems and servos used in VTRs, the need for self-diagnostics has been recognized. By adding feedback to a microcomputer-based system, it is now possible to constantly monitor many of the VTR's operating parameters. This article describes the fault-detection and isolation system of the Ampex VPR-80 that can aid engineers in troubleshooting faulty assemblies.
