Epoch-M1C RF RepeaterUser Manual V1.1Advanced RF Technologies, Inc. Proprietary Document Page 18 of 382.1.3 Control Menu2.1.3.1 General Setting WindowAGC ModeAGC (Auto Gain Control) adjusts the variable gain of the repeater to ensure aconstant specified output power of 20 dBm. The functionality of the AGC featureis assured under the condition that the input BTS signal is within the specifiedAGC range (-60 to -35 dBm => assuming AGC Level is set to 20 dBm) and thatsufficient isolation exists between antennas (≥ 93 dB). By default, theAGC ONbox is checked. To manually change the gains in both the links,AGC ON mustbe unchecked.IfAGC ON is checked andUplink Tracking ON is unchecked, the user can specifythe AGC level in the downlink and in the uplink respectively @ 0.5 dB step (0 to20 dBm). By default, the AGC Level is set to 20 dBm in each link.Downlink/Uplink HPA ModeThe HPA mode enables the user to turn the HPA on or off. If the HPA is turnedoff on either link, the Epoch-M1C will not operate properly. Both HPAs needs tobe turned on for the RF portion of the repeater to work in both directions(downlink and uplink). By default, theDownlink/Uplink HPA ON boxes arechecked.Either or both HPAs can be turned off for troubleshooting purposes during aninstallation process.Figure 7 - General Setting Window of the Epoch-M1C Software
