Halaman Cetak2.4 Hardware AGC
Hardware automatic gain control (AGC) circuit is intended to prevent undesired oscillations and spurious
emissions. The repeater can experience oscillating conditions due to wrong installation factors like small
isolation between outdoor donor and indoor coverage antenna isolation. In the case of too high input
signal hardware AGC limits the total output power to a value in dBm specified for each model.
Two orange LEDs (DL and UL separately) show the activity of hardware AGC. If they are active, input
signal is too high or repeater is oscillating.
In case of higher input signal built-in additional digital step attenuator can be used to decrease gain of the
repeater. Also using directional donor antenna or a different faraway BTS could be chosen.
2.5 Connectors, indicators, buttons
SMA connector has a torque 0.5 N/m. N-type connectors have a torque 1.3 N/m. Use appropriate tools
when working with these connectors.
For installation convenience control part (LEDs, USB, RESET button) is placed on inside of the CSR-DMT
in front position. On bottom side of the CSR-DMT RF connectors, power supply input and other additional
connections are placed.
