Learn about a new, unique THz-frequency probe arm option for cryogenic probe stations. The solution enables precise probing of millimetre-wave devices at 75–110 GHz or 140–220 GHz frequencies, allowing calibrated S-parameter and other high-frequency measurements to be performed as a function of low temperature and magnetic field.
