Featuring best-in-class sweep speed and unique test capabilities, the BTS Master-based CPRI RF measurement test set allows field engineers and technicians to conduct accurate RF measurements on Remote Radio Heads while remaining at ground level, eliminating the considerable expense and time associated with calling a tower crew to conduct interference measurements. With the new option installed, the BTS Master can conduct RF measurements over the fiber optic CPRI link connecting the baseband unit and RRH.
