Combiner
In higher power systems that contain more than one power amplifier enclosure, there also is a
combiner enclosure to combine the individual outputs of all of the power amplifier enclosures.
This combiner enclosure also monitors the total power of the overall system. The following is a
brief description of the operation of the monitor system found in the combiner unit, if applicable.
Carrier On/Off – Turning the carrier on or off can be done from the touch screen or the remote
port on any power amplifier or the combiner enclosure. It can also be done from SNMP or the
Ethernet interface which should be connected to the combiner enclosure. This will turn the
carrier off for the whole system.
Carrier Up/Down – The power level can be adjusted from the touch screen (RF Levels screen)
or the Remote Port on any power amplifier or the combiner enclosure. It can also be done from
the SNMP or Ethernet interface which should be connected to the combiner enclosure. This will
add or subtract attenuation on the individual power amplifier enclosures to achieve an overall
change in carrier level, and sets the AGC to the new levels if the AGC mode is enabled.
AGC mode – AGC mode and be turned on or off from the touch screen (RF Levels screen) or
the Remote Port on any power amplifier or the combiner enclosure. It can also be done from the
SNMP or Ethernet interface which should be connected to the combiner enclosure. This will
cause all the amplifier boxes to try and maintain the current forward power level.
Temperature, Voltage, Current - Temperature, voltage, and current readings on the enclosure’s
touch screen are for that unit only. The SNMP and Ethernet interface will show each units’
readings separately, and should be connected to the combiner enclosure.
Forward & Reflected Power – Forward and reflected power shown on the touch screen or the
Remote Port are for that power amplifier enclosure only, or show the total combined power if it
is on the combiner enclosure. The SNMP and Ethernet interface will show each units’ readings
separately, and should be connected to the combiner enclosure.
Display Units – Changing the temperature or power units on one enclosure won’t change the
display units on other enclosures. They will all have to be changed individually.
VSWR Trip point - The VSWR trip point between 1.1 and 1.8 can be changed from the touch
screen (RF Levels screen) on any power amplifier or the combiner enclosure. It can also be
done from the SNMP or Ethernet interface which should be connected to the combiner
enclosure. This will change the trip point for all the units.
Errors – An error that causes one enclosure to shutdown will cause the other enclosures to
shutdown. If one power amplifier or the combiner is to fold back its power levels to stay within
operating parameters, the others will match that power level.
