AGC Mode
AGC (Auto Gain Control) adjusts the variable gain of the repeater to ensure a
constant specified output power of 20 dBm. The functionality of the AGC feature
is assured under the condition that the input BTS signal is within the specified
AGC range (-60 to -35 dBm => assuming AGC Level is set to 20 dBm) and that
sufficient isolation exists between antennas (
≥
93 dB). By default, the
AGC ON
box is checked. To manually change the gains in both the links,
AGC ON must
be unchecked.
If
AGC ON is checked and Uplink Tracking ON is unchecked, the user can specify
the AGC level in the downlink and in the uplink respectively @ 0.5 dB step (0 to
20 dBm). By default, the AGC Level is set to 20 dBm in each link.
Downlink/Uplink HPA Mode
The HPA mode enables the user to turn the HPA on or off. If the HPA is turned
off on either link, the Epoch-M1C will not operate properly. Both HPAs needs to
be turned on for the RF portion of the repeater to work in both directions
(downlink and uplink). By default, the
Downlink/Uplink HPA ON boxes are
checked.
Either or both HPAs can be turned off for troubleshooting purposes during an
installation process.
