Title:
TRANSFER IMPEDANCE MEASUREMENT INSTRUMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO2000044077
Kind Code:
A3
Abstract:
The invention is an apparatus and method for measuring the transfer impedance of a structure. Oscillator driver (20) produces a small electrical drive signal into structure (40). Field probe (30) detects the electric field produced by the drive signal and is comprised of a skinny half-dipole and fat half-dipole antenna. Fat half-dipole (34) encloses synchronous detection circuitry. Power supplies are isolated for all components. Base station (10) communicates with oscillator driver (20) and field probe (30) via wireless links (92) and (44) to control the drive signal, the synchronous detection, and to determine the transfer impedance.
