NLDS measurement setup (schematic). The voltage control signal is applied by a symmetric amplifier to the outer two of a plane 4 gold electrode array. The NLDS signal generated by the sample is clamped by the inner two electrodes. It will also be preamplified symmetrically, digitized by a fast computer controlled analog-digital converter and fourier analyzed by the data acquisition software. The static and dynamic magnetic field component is directed parallel to the electrode plane. The measuring station provides two such NLDS setups, enabling a simultaneous examination of two samples under same conditions.
