AGC and MGC Options on Z-Light Fiber Transmitter

AGC (Automatic Gain Control) is a closed-loop feedback circuit in RF (Radio Frequency) receivers that automatically adjusts the amplification (gain) of the incoming signal. It maintains a stable, usable output level regardless of whether the input signal is exceptionally strong or very weak. 

MGC (Manual Gain Control) The user must manually adjusts the amplification (gain) level of an RF amplifier or receiver rather than letting the system do it automatically 

Z-Light Fiber Transmitters ship with MGC enabled and a pre-set value for attenuation (11dB) as required by a 20dBmV RF input signal. In a Z-Band video distribution system AGC setting is used by Z-Distribution ZHC's internal fiber receivers and hence there is no need for AGC option in the Z-Light Fiber Transmitters.
