4.4.2 ALC (Auto Limit level Control) Function
1. If UL output power level of RHU reaches the ALC level, RHU decrease the output power to
maintain ALC level automatically.
2. When power level goes down under ALC level, RHU increase output power until ALC ATT is 0 by
500msec ~ 1sec speed.
4.4.3 AGC (Auto Gain Control) Function
1. In order to have stable output power, RHU has AGC function that can maintain constant output
power with setting output level.
2. When input level is decreased RHU increase gain to maintain continuous output level, when
