3.3 Functions

ITEM FUNCTIONS

Gain Control

• Adjustable DL and UL Gain range 50~90dB(PCS)

• Adjustable DL and UL Gain range 60~90dB(iDEN800/900)

• 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.

• Used with the Automatic Setup (Auto Gain Setting)

ALC

(Auto Level Control)

• To limit output power as far as default range

• Used for DAS configuration and when oscillation/isolation is a concern

• 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

AGS

(Auto Gain Setting)

• Operate when User control (Only system initialize)

• Decrease attenuator value for 3dB from minimum gain

• In case of attenuator value is from 0dB to 3dB when AGS ended

- AGC on (DL)

- Gain balance on

- PAM on

- Shutdown on

• In case of attenuator value is over 3dB when AGS ended

- AGC off (ALC on)

- Gain balance on

- PAM on

- Shutdown on

Gain Balance • Downlink ATT is applied to Uplink during AGC state
