An embodiment provides a measurement arrangement for characterizing a radio frequency arrangement comprising a plurality of antennas. Measurement arrangement comprises a dielectric waveguide slab with a plurality of frequency converting structures, arranged in or on the dielectric waveguide slab. Measurement arrangement further comprises a plurality of waveguide transitions arranged at different positions of the dielectric waveguide slab and are coupled to respective radio frequency components. Radio frequency components are configured to transmit and/or receive radio signals. Frequency converting structures are associated with respective antennas of the plurality of antennas, and are configured to perform a frequency conversion on signals received, resulting in frequency-converted signals. Frequency converting structures are further configured to couple respective antennas with the dielectric slab in a frequency converting manner to establish a frequency-converting coupling between the antennas and the plura
