   Vema-04.1, a four channel magnetometer, which is currently being developed at Department of Aviation Technical Studies, has an innovative design of sensor’s electronic circuits, based on complex programmable logic device (CPLD). By change in CPLD program, we are able to set different magnetometer operating modes, directly influencing its sensitivity. As the sensors (detecting elements and electronic circuits) are in principle digital, it is possible to influent sensitivity directly by the system clock management. For determining sensitivity of each magnetometer channel we have used a pair of Helmholtz coils (HC). The article deals with sensitivity determination for all four channels of the developed magnetometer.

Keywords: magnetometer, measurement, sensitivity, static conversion characteristic
