Helmholtz Tester

Resonance Detector and Rapid Tester

Detects a magnetic resonant receiver placed on the test platform inside the RF Helmholtz coil. It uses a VNA to detect the presence of a resonance within a pre-defined frequency range. Upon finding a resonance, the apparatus will report the resonant frequency, resonant quality factor, and the dipole volume, which characterizes the coupling strength to the surrounding magnetic field. Needle probes are included which can provide a DC bias to nonlinear components on the receiver.

A computer screen displays test results with green and blue background, showing measurements and quality indicators. Above it, a metal and plastic testing apparatus with three probes connected to wires is positioned on a black stand against a white wall.
