Antenna Distribution System
Multiple Levels of Antenna Distribution
For large configurations, multiple Antenna Distribution Systems can be layered to support several levels of signal distribution:
•
Two levels of antenna distribution are possible if the level 1 and level 2 Antenna Distribution Systems have the Cascade ports activated
•
Up to 3 levels of antenna distribution are possible if only the level 1 Antenna Distribution System has the Cascade ports activated
•
For best RF performance, use all the RF outputs on one level before creating additional levels
Level 1: Antenna Distribution System set to Wideband
Level 2: Antenna Distribution System set to a band filter matching the 4 receivers tuned to the same band
Connect the AXT600 Spectrum Manager to the RF cascade ports of the Level 1 Antenna Distribution System
Troubleshooting
Antenna Faults
Antenna
The antenna input status LED flashes red to indicate a short or over-current
condition at an antenna port. To isolate the fault, navigate to the DC power
menu. The menu displays which antenna port (A, B, or A+B) is the source
of the fault. Check the antenna connections to remove the fault condition.
Main Menu
Use the main menu to select the band filter, adjust the RF gain, and configure
the antenna ports.
Band
Selecting an input Band filter optimizes performance when the components
connected to the RF outputs are all within the same band. The selected band
filter will only pass frequencies within the range of the connected components.
Four selectable input filters are available to match the frequency bands
transmitters and receivers. A Wideband setting is available to extend frequen-
cy support across all 4 bands. This setting allows receivers operating in a
variety of bands to use the RF outputs.
To set the Band filter:
1. Navigate to the Band menu and press the SET button to enable editing.
2. Use the arrows to select a band filter or to select the Wideband setting.
3. Press the SET button to save changes.

Over Temperature Message
The Over Temperature message is displayed when the fans are unable to
cool efficiently, indicating an elevated temperature condition.
•
Press any button to suppress the message for 20 seconds
•
Increase ventilation to the unit to clear the message
•
Select the High Speed setting for the cooling fan
RF Gain
Adjust the RF gain to boost or attenuate the antenna signal to maintain con-
sistent levels and prevent overload. Gain adjustments are made in 1 dB in-
crements.
The gain adjustment range depends on the connection status of the RF
cascade ports:
•
Cascade ports connected: adjustment range = -15 dB to 0 dB
•
Cascade ports not connected: adjustment range = -12 dB to +3 dB
