ABSTRACT
The methods and requirements necessary to perform accurate and reproducible polarisation-field (P-E) measurements are discussed. An introduction to P-E measurements is given outlining the electrical origins of the P-E loop and visual interpretation of loop characteristics. Conventional and computer based measurement systems are reviewed followed by a description of P-E signal analysis techniques.
The DynoHYST apparatus, developed at Leeds is introduced and principles of operation are discussed. Methods and uses of electrical breakdown and ferroelectric saturation detection are presented. Particular reference is made to the dual applicability of DynoHYST to both research and production quality assurance and on line testing.
