5.8.2.2. AGC and ASD Function
AGC (Automatic Gain Control)
: AGC feature prevents the repeater from exceeding its maximum output
power by reducing the gain automatically. AGC is used to adjust the gain to an appropriate level for a range
of input signal levels.
ASD (Automatic Shut Down ) : ASD protects the repeater from oscillation or excessive input signal and
eliminates any degradation to the network.
There are three parameters: ASD Level, ASD Time, and ASD Iteration.
If the output power reaches higher than the “ASD LEVEL”, the repeater will shut down for “ASD TIME”
seconds and then turn the amp back on to measure output power. If shut down repeats “Iteration” times,
the repeater will shut down permanently.
<AGC Example>
[applied at the Quadcomm-800]
Select AGC On and enter a value equal to or less than 30dBm, click APPLY and ON.
For a repeater with 25dBm maximum output power, 90dB maximum gain/25dB gain Control range,
Æ If the input signal is -65dBm and AGC level is 15dBm, the gain will be 80dB.
* To apply this for each Band refer to Automatic Gain Control Setting following section of 5.6.
