7.10.3 RF Configuration
CAUTION!
Configure the RF output signal for each port only when the corresponding optical input power level is known to be
within acceptable limits.
Configure the RF output signal level on each port in accordance with local requirements:
1.
Change the “Output Gain Type” to “MGC” mode.
2. Adjust the “Output Gain Control” level until the RF output is at the required level.
3. If the RRAS / RRAG receiver path uses a continuously emitting laser as the transmitting carrier, you can change
the “Output Gain Type” to “AGC” mode.
4. Finally, set the required AGC mode.
In “AGC” mode, the port adjusts gain by using the optical input power as a reference.
The factory default value of output gain is 42 dB and the adjustment range of the optical input level is ± 5 dB.
Note:
AGC mode will be maintained with variance in the optical level.
CAUTION!
Both types of AGC modes use the current Output RF Pad Level setting in order to stabilize the output. If the RF pad
level is set either too high or too low, this will affect the AGC control range.
