defined value. The output attenuator’s adjustment range is above 25dB. If output power
decease, applied ATT by AGC function return to initial ATT
7.3 Output power automatic setting function (TX Output AGC)
To provide convenience of setting output power at initial setup automatically, operator
set to wanting output level and turn-on the AGC function and then output power is
automatically set to defined level.
If AGC logic finished, logic operation results show on the result window of GUI. There
are three types of results as follows
1. Success: The AGS function is normally completed.
2. Not Opterate OPTIC Comp: Optic Comp is not executed.
3. Lack of ATT: There is no attenuation available.
If normal logic don’t executed, changed ATT return to initial ATT
Through output AGC function, can be checked whether optic compensation is executed
or not
7.4 Input power AGC function (TX Input AGC)
This function is to give convenience to operator when setting intial installation
Without spectrum analyzer, we can know input power value through power display
window of GUI. Use TX IN AGC function and automatically set internal ATT depending
on input level. ATT is automatically set based on -20dBm of input . The table below
shows TX IN ATT depending on TX IN POWER. For manual setting, you can set ATT
depending on input according to the table.
TX IN POWER TX IN ATT TX IN POWER TX IN ATT TX IN POWER TX IN ATT
