System of 104 diagnostic saddle loops is used to measure magnetic response of rotating tokamak plasma to stationary n=2 magnetic perturbations, generated by RMP windings located on the outboard side of the chamber. The measured response is compared to linear MHD simulations by MARS-F code. Two different RMP field configurations (i.e. of different m spectra) are investigated this way. Good agreement between measurements and model is seen on the top and bottom part of the chamber, but not as good agreement on LFS. The change in RMP configuration affects only the amplitude of the response field - the waveform of its poloidal distribution is unaffected.
