The method does not require modification of the connections to the microwave assembly within the housing. The housing or package only need have a flat lid and that it be left off so that the item under test can be mounted on an equivalent flat plate on the test instrument. The microwave assembly in the housing or package may be operated normally while resonant field distributions are being measured. The prototype instrument yields results that demonstrate the practical application of this measurement assembly as a diagnostic and design development tool for microwave housings and packages of rectangular metal box shape. Resonances in the 8-12-GHz range have been accurately measured and indicate that by scaling dimensions an assembly for use at millimeter wavelengths is feasible.<<ETX>>","PeriodicalId":439545,"journal":{"name":"[1991] Conference Record.

Unfortunately, much of that data is not often used unless a major problem has occurred. A technique in which data can first be analyzed to determine what is normal variability in the process and a model or models developed which define in a compact way that variability are presented. The information in the models is then used to measure the state of the process as to whether it represents a likely sample from the model of normal variations. If it is not, information about why the data are not of the form expected is made available to the operators in a readily understandable manner. This technique was researched and implemented on a solution area of a Du Pont plant. The approach taken is to first separate out the major effect of rate variations which are normal and a major contributor to the total variability of the data. On the residuals of the model, a principal component analysis (PCA) model determines if that data fit the pattern of normal variations. If not, then what went wrong is analyzed, and why the data are different and what changes might be made to get the operation into the acceptable region, are determined.<<ETX>>","PeriodicalId":439545,"journal":{"name":"[1991] Conference Record.
