Precision Coaxial Connectors in Lumped Parameter Immittance Measurement

Amid the concern surrounding the design and application of precision coaxial connectors for use in precise electrical measurements there is one area which has received very little attention. This has to do with the application of such connectors to measurements in the lumped parameter region. This paper points out significant sources of error in lumped parameter measurements which are attributable to connector uncertainties and shows how they can be greatly reduced through the application of precision coaxial connectors. Where these connectors are utilized in lunped parameter immittance measurements, extensions of frequency, magnitude, and accuracy are realized. Specific examples are discussed.
