About AS-84

Introduction  :
The AS-84 is a combiner and a splitter in a small form factor. 4 inputs and 8 outputs. Wideband and tunable narrow band filter are buitin. 4 inputs allows you to do zoning, it means summing signal from antennas to cover to different place or cover a broader area.

Keypoints  :

  • 2 antenna input pairs, selectable or summable
  • Wideband and tunable narrowband filter buit-in
  • 12V regulated DC feed
  • RF power bargraph
  • Compact and rugged

What is needed with AS-84 :
-Power source (9 -18V) and power cable (4 point push pull type)
-Two 50ohms coax for antennas(BNC), coax for receivers(SMA) and SMA loads for unused ports.

Description

Connecting  :

  • Connects outputs to wireless receiver inputs (or combiner, splitter)[4/5].
  •  Connects inputs to antenna thourgh coax cable[1/2].
  • Connect power to DC[3]. Pinout : 1,2:GND 3,4:VIN
  • Add DC feed on requested port (DC) and select the input port (1 or 2 or 1+2 sum).

Leds :
Peak:

  • Those leds light up when the signal exceed the RF threshold .This threshold can be set in the menu.

DC :

  • Those leds light up when the corresponding DC feed is applied to the port.
    It will blink if a too much is drawn or if there is a short circuit.

SW  :

  • SW leds indicate witch input channel is selected

Display

Oled display :
Main screen displays (Illustration 1):

  • Filter selected and frequencies
  • RF bar power (-40 up to 0dBm)
  • DC feed configuration
  • RF input selection
  • In menu set thresholds

Unlock  :

  • Press the switch for until the locker is unlocked (right bottom side of display)

Filter :

  • Press the switch and rotate encoder to select WB(wideband) or NB(narrowband) filter. In NB anothr pression will allow you to tune the central frequency of the filter

DC feed & input selection :

  • Press encoder to select DC and rotate encoder to change the DC config, do the same to change the SW config aka wich input are selected

The ‘*’ appears next item that can be modifed using the encoder.

Using 4 antennas, two configuration :
-Extending zone : area are overlapping. It means that antenna 1 and 2 receive in overlapping zone the same signal.
-Multizone : area are not overlapping. It means that antenna 1 and 2 don’t receive the signal of the other zone (or with attenuation).
