The design and realization of a cryogenic rig for point-contact spectroscopymeasurements in the needle-anvil configuration is presented. Thanks to the useof two piezoelectric nano-positioners, the tip can move along the vertical($z$) and horizontal ($x$) direction and thus the rig is suitable to probedifferent regions of a sample \textit{in situ}. Moreover, it can also formdouble point-contacts on different facets of a single crystal for achieving,e.g., an interferometer configuration for phase-sensitive measurements. For thelatter purpose, the sample holder can also host a Helmholtz coil for applying asmall transverse magnetic field to the junction. A semi-rigid coaxial cable canbe easily added for studying the behavior of Josephson junctions undermicrowave irradiation. The rig can be detached from the probe and thus usedwith different cryostats. The performance of this new probe has been tested ina Quantum Design PPMS system by conducting point-contact Andreev reflectionmeasurements on Nb thin films over large areas as a function of temperature andmagnetic field.
