Dielectric measurements using the HP 85070A probe

The authors describe the techniques for permittivity measurements using the Hewlett Packard HP 85070A Dielectric Probe Kit. The HP 85070A probe provides a flexible means of dielectric measurements with only minimum sample preparation. Results from measurements of the dielectric constant of liquids and solids are presented for dielectric constants ranging from 2.5 to 80 and for lossless and lossy materials. The focus is on techniques for sample measurements and the accuracy, repeatability, and resolution obtained with this HP probe for performance characterization and evaluation.<>
