Setting Up Transponders, Continued SMC Transponder Use a SMC transponder to set up the parameters that are highlighted in the following illustration. CAUTION: The SMC transponder can only be recognized by the amplifier when it is set to IEP mode. To change the mode, connect a handheld, part number A91200.11 to the LCI interface of the transponder.
Starting Up the Amplifier with the AGC Module The following sections describe how to operate amplifiers with the AGC module mounted. The LEDs on the AGC module indicate the status of the module when it is mounted. When the amplifier is powered up, and during initialization of the AGC module and amplifier, the three LED indicators with different colors flash in sequence for approximately 50 seconds.
Setting Up the AGC Module When the AGC module is plugged into the amplifier, it reads the settings, including pilot settings and function settings from the amplifier, and starts to run the configured function. CAUTION: When a SMC transponder will be installed, make sure its mode is set to IEP, before configuring the AGC module.
Functions of the AGC Module Standby If no function is required, the AGC module is automatically set to Standby mode to reduce power consumption. The standby mode is running in a cycle of 2 minutes between monitoring and sleeping. In monitoring status, the AGC module detects the levels of 4 pilots and the selected frequencies and sends the information back to the handheld or the ROSA Element Management system.
Functions of the AGC Module, Continued The AGC function continuously adjusts output attenuators and equalizers up to ± 4 dB, to keep the output level and tilt of the amplifier constant. This function runs in a cycle of 6 minutes to save power. During each AGC tuning session, the AGC module monitors 4 pilot levels and 10 selected frequencies, and when the amplifier detects that the adjusting values of attenuator and equalizer are out of the ±...
Temperature Back-off Introduction The temperature back-off feature is used to off-set the attenuator and equalizer when the amplifier is auto aligned at a non-room temperature, to allow the AGC module to work at room temperature. This feature is used for the auto alignment function only, and is turned off when the auto alignment is completed.
