Two electronics prototypes for the ITER outer vessel steady-state magnetic field Hall sensors based ona lock-in signal processing and current spinning technique were developed. The prototypes, the firstusing a rectangular lock-in signal processing with sensor offset cancellation and the second employ-ing advanced lock-in signal processing with sensor and electronics offset cancellation, were comparedwith a DC technique and commercial lock-in amplifier. The influence of long interconnection cables,white noise, and interfering planar Hall effect to a measurement accuracy was evaluated. The planarHall voltage suppression by the current spinning technique was investigated. Whilst the rectangularlock-in amplifier prototype failed to meet the ITER accuracy requirement, the advanced lock-in amplifierprototype demonstrated required functionality and accuracy.
