The report describes the construction of an automated absolute magnetic field generation system using a 0.5 meter radius Helmholtz coil. The system operates over a frequency range of dc to 20 kHz and can generate field strengths up to approximately 1 Gauss RMS. The theoretical fields in the region surrounding the coil were calculated and compared with measurement. The system is used for the evaluation of broadband survey meters and calibrated antennas.
