Description 
Scientific-Atlanta’s AGC (Automatic Gain Control) Amplifier meets 
the needs of today’s operators advanced networks and services, 
i.e. ease of installation, flexible operation and reliability. The AGC 
amplifier type 93208 is an 862 MHz amplifier optimised especially 
for AGC applications. 
 
Intelligent Processor 
The integrated intelligent processor controlled AGC module 
provides optimal adjustment under all circumstances. Compared 
to traditional AGC amplifiers’ more complex set up and manual 
adjustment procedures, set up is done by pressing just one 
button! 
 
The pilot frequencies are selectable and may be altered  
on site according to the actual channel load – no factory set pilot frequencies!  
 
The AGC Amplifier can measure the output level as an absolute value - not only relative. This means that the 
AGC amplifier can be set up without using a measuring instrument. If desired, the amplifier may even be set 
to the desired operational level before it is installed! After that: install - push the button - finished! 
 
Element Management 
The AGC amplifier can be configured with a Compact Transponder to enable status monitoring and on-screen 
presentation of key parameters. Output level, temperature, input remote supply voltage and internal DC 
supply voltage as well as AGC status are such key parameters. An alarm generated by the element 
management system enables the operator to detect failures even before visible to the subscribers.  
 
Besides serving as an AGC amplifier, the unit can accurately monitor the level of a carrier within the forward 
frequency band. The frequency of the carrier may be freely changed. 
 
 
Features 
• 
Push one button only for extremely fast and easy adjustment 
• 
GaAs-FET technology for superior performance and improved longetivity 
• 
Free selectable pilot tone frequencies. Pilot tone from generator or analogue TV carrier 
• 
Accurate level measurement of the freely selectable carrier 
• 
Optional status monitoring and control 
• 
Element Management measuring of absolute levels on analogue carriers eliminates the need for 
measuring instruments for set up and allows individual channel monitoring 
• 
Easy plug-in mounting of transponder (no change of lid nor use of test points for cable connection) 
• 
Integrated 3-state reverse switch (on/-6 dB/off) allows each reverse input to be isolated for  
noise and ingress 
• 
The Proactive Power Supply Monitor locates failures prior to network outages for improved reliability
