Abstract :
Results of dynamic measurement using plug-in A/D boards are influenced not only by quality of the board but also by internal and external environment. Problems of measurements of analog signals in magnetic field are discussed in the present paper. Results depend mainly on magnetic field intensity, direction and frequency, but signal connection and board input configuration are also very important
