The High-Luminosity upgrade of the Large Hadron Collider Luminosity (HL-LHC) requires new high-field and large-aperture quadrupole magnets for the low-beta inner triplets (MQXF). CERN and LARP collaboration are currently developing a 150-mm-aperture quadrupole based on Nb3Sn superconducting cables for the coils, and an aluminum shell with the bladder-key technology for the support structure. This paper presents the test setups for magnetic measurements, both at ambient and cryogenic temperatures, and the instrumentation being used for the first two short-models of MQXF built and tested at CERN. Finally, the measurements results, in terms of field quality, effects of persistent currents, and iron saturation, are reported and discussed.
