A signal power tester in provided. The signal power tester includes at least one interface to communicatively couple the signal power tester unit to a front-haul communication link used for communicating front-haul data to a remote radio head (RRH) having one or more antenna ports. The signal power tester further comprises a programmable processor, coupled to the interface, configured to execute software, wherein the software is operable to cause the signal power tester to do the following: determine a representative segment indicative of a noise floor of a communication signal; determine whether the representative segment meets selected criterion; determine a translation factor for the representative segment; and measure power of the communication signal based on applying the translation factor.
