This article studied the radio station inspection method, which utilizes the 8T8R combiner to reduce 5G radio station inspection measurement times. It is a common that 5G radio station inspections measure RF (Radio Frequency) output signals, which correspond to the number of arrayed antennas individually. However, this study suggested a way to save the time spent on existing methods, by comparing measurement values of individual channels and 8T8R. As a result, it is confirmed that when the 8T8R combiner is used, not only the resulting value of radio station inspections was accurate, but also the measurement time being shortened by up to 8 times compared to existing method.
