THE NEW APPROACH TO THE RANGE EXPANDING IN IMPEDANCE MEASUREMENTS

Abstract

To measure the impedance parameters in the wide dynamic range we need always the great number of the standards. The precise standards, used for the accurate measurements are very expensive, have great sizes and weight. Therefore, the appropriate devices have great cost and dimensions. In this report we describe the approach, which permits to reduce twice the number of standards, used for the widening of the measurement range. This approach is based on the measurement ofthe reciprocal impedance parameters on the two adjoining subranges of measurement.
