Abstract

This paper describes design results of the measurement system to test the properties of broadband AC magnetic field sensors used in weapon system. This measurement system consists of 3-axis helmholtz coil, signal generator, signal amplifier, sensor data acquisition unit and measurement & analysis controller including the operating software. This system is able to measure various properties of AC magnetic field sensor such as sensitivity, linearity and dynamic response in the frequency of 1 Hz to 10 kHz. The performance of this system was verified by measuring and analyzing the property of a MAG 639, standard magnetic field sensor of bartington instruments, with this developed system.
