• AGC Alignment
With an input signal level of – 30 dBm, with coarse gain on, fine gain at max and AGC on, adjust R12 to obtain an output
level in accordance with the table below. Settings are derived using FCC recommended procedure for determining
channel loading of multichannel amplifiers.
APPLICATION AGC Single Carrier Target Level
Standalone Booster +20 dBm
Booster used with SMA 20W Amplifier +15 dBm
Booster used with TRL 35W Amp with +51dBm IP3
+10.5
Booster used with TRL 35W amp that conforms to +55.5
dBm IP3
+15 dBm
• Verification of Fine Gain Control
With a single carrier input level of –50 dBm, AGC off and all gains set to max, observe the output level while decreasing fine gain
step by step. Verify that steps are monotonic and that with fine gain set to minimum, overall gain is less than maximum gain by 16
dB +/- 0.7 dB. (Monotonic means that the steps are in the right order, that when you reduce gain by any 1 dB step, the gain
change is in the right direction. Some attenuator faults may result in steps getting out of order when you cross a high bit
boundary.)
• INSTALLATION OF BOTTOM COVER
Install labels (uplink/downlink) near 9 pin connectors. Ensure labels go with correct PCB boards.
Install bottom cover (to assembly using 16 #2-56 flat head screws.
• FINAL TEST AND INSPECTION
If required by customer contract, repeat swept measurement at full gain to produce a final plot for shipment to customer or
for file. This also verifies that cover installation did not disrupt the circuitry as gaskets were compressed.
Inspect housing for missing screws.
Affix nameplate with serial number.
Pack unit for shipment if applicable.
