M easurement Function
Item Specification
VSWR alarm reporting The RU supports Voltage Standing Wave Radio (VSWR) alarm reporting on all external TX RF connections by
measuring the TX RF-signal return loss.
The VSWR is less than 1.5 for each port under all operating and environmental conditions. When VSWR at
any port exceeds 1.5, the RU reports an alarm to the EM S and the RU stops to transmit power in order to
protect the RU from damage. The alarm indicates which port has exceeded the VSWR requirement. Refer to
RU Alarms.
Noise floor measurement The RU supports the function of measuring the Received Total Wideband Power (RTWP), when initiated by
EM S or when initiated by the DU.
