Abstract
A test device for testing a power of a signal at a cell site using RFoCPRI™ is disclosed. The test device may comprise a receiver to receive a signal from a test point near a baseband unit (BBU) of a cell site. The test device may also comprise a processor to determine power of the signal. The processor may identify IQ data from the signal, determine an offset based on a noise floor determined from at least one specification of a remote radio head (RRH) of the cell site, and generate a power spectrum based on the IQ data and the offset. The processor may transmit the power spectrum to an output (e.g., display), where the power spectrum may be representative of the power of the signal between the RRH and antennas of the cell site.
