INSTRUMENTATION AND MEASUREMENT TECHNIQUES STUDY
Abstract
Work was continued in several areas of investigation intended to advance the state of the art of electrical measurements. A square wave technique for isolating faulty components in conventionally-wired or printed circuitry without the need of unsoldering was implemented and is described. A modified sawtooth signal shows promise of isolating faulty semiconductor devices in-the-circuit. A survey of recording and readout techniques other than the normally employed magnetic devices is presented. This discussion outlines the problem areas in thermoplastic recording Kerr magneto-optic and electron beam readout devices. Techniques for locating faults in long-line spiral-four systems are discussed. Two correlation techniques are discussed, and a breadboard impedance-phase angle measuring device is described. An investigation of the properties of spiral-four cable is also described. (Author)
