O-RU energy efficiency testing

Radio units contribute greatly to the total power consumption. Rohde & Schwarz offers a proven, automated test solution together with VIAVI Solutions that explores how radio unit power consumption varies under different user conditions through the application of ETSI-defined load profiles. The radio unit activity versus power consumption is monitored using the R&S RTO oscilloscope to detect short power pulses or spikes. The results make it easy to evaluate energy efficiency measures such as advanced sleep modes and provide ratings for radio units based on their power consumption. The R&S NGP power supply units power the radio unit and monitor voltage and current statistics over time.
