Installation of modern highly sensitive magnetometric equipment at geophysical observatories requires location of places with a low level of magnetic noise. It is also required to perform regular control of noise environment at observatory instrument installation points. This work is aimed at testing one of the prototypes of magnetic noise measuring instruments, capable of performing fast areal measurements. The key features of this prototype are high sensitivity and linearity and capability of registration of magnetic noise in different frequency bands.
