10.6.9 HPA Current Misbalance Warning
HPA Current Misbalance Warning - set
when the lowest current (A) reading on one of the
power modules is less than 20% of the highest current (A) reading on one of the power
modules.
NOTE: The maximum output power level of the HPA will be limited to 53 dBm if a HPA
Current Misbalance Warning alarm occurs. The Web-GUI interface has no control over this
action.
• If the output power level is > 53 dBm, it will be automatically reduced to 53 dBm.
• If the output power level is < 53 dBm, no reduction will occur.
