3.3 Functions
Parameter Specification
Gain Control
• Adjustable DL and UL Gain range 55~95dB
• Display default Gain and current Gain function
AGC
Auto Gain Control
• It always operates in Downlink AGC ON status
• To maintain same Downlink output power despite flexible input signal
strength.
• To add or subtract Attenuation level referring to AGC Power Limit level.
ALC
Auto Limit Control
• To limit output power as far as default range
• Set up via GUI
• Automatic Gain decrement when output power of repeater is higher than
default level
• Automatic Gain recovery when output power of repeater is reduced.
• Shutdown when output power is higher than default level in Minimum Gain
• Automatic Recovery Algorithm conversion after Shutdown status
Gain Balance
• Downlink ATT is applied to Uplink during AGC state
• Setting and maintenance of output level
• Additional attenuation to ALC Level
Oscillation Check
• Isolation Check in initial set up or Reset
• Monitoring Oscillation comparing to minimum/maximum Noise Floor level
• When Oscillation occurred, repeater attempts to stabilize Isolation through
Gain control function.
• Shutdown repeater when Oscillation still goes in Minimum Gain
• Automatic Recovery Algorithm conversion after Shutdown status
Spurious Emission
Alarm
• Noise Floor Observation in case of ±2.25MHz down at the center
• In case of Noise level > –13dBm, Spurious Emission is stabilized
automatically
• In case of Oscillation Spurious Emission Alarming in Minimum Gain,
repeater will be shutdown
• Automatically Switch to Recovery Algorithm at Shutdown
