Setting Up the Four Object Configuration

This section describes the module location and connection sequence for the four object VRTS configuration. This configuration uses four VDG modules and two VST modules. Insert the modules into the chassis as shown in the following image. Refer to Installing the Modules for more information about inserting the modules.



To cable your modules, complete steps 1 through 11 in numerical order. Reference the subsequent figure to verify that your modules are properly cabled.

  1. Use three 0.09 m MMPX R/A-SMA R/A cables to connect the following modules:
    1. Connect the SHORT OUT port of the VDG in slots 4 through 6 to the RF IN port of the VDG in slots 7 through 9.
    2. Connect the SHORT OUT port of the VDG in slots 7 through 9 to the RF IN port of the VDG in slots 10 through 12.
    3. Connect the SHORT OUT port of the VDG in slots 10 through 12 to the RF IN port of the VDG in slots 13 through 15.
  2. Use three 0.07 m SMA R/A-SMA R/A cables to connect the following modules:
    1. Connect the SHORT IN port of the VDG in slots 4 through 6 to the RF OUT port of the VDG in slots 7 through 9.
    2. Connect the SHORT IN port of the VDG in slots 7 through 9 to the RF OUT port of the VDG in slots 10 through 12.
    3. Connect the SHORT IN port of the VDG in slots 10 through 12 to the RF OUT port of the VDG in slots 13 through 15.
  3. Use two 0.11 m MMPX-MMPX cables to connect the following modules:
    1. Connect the LO OUT port of the VST in slots 2 through 3 into the LO IN port of the same VST.
    2. Connect the LO OUT port of the VST in slots 16 through 17 into the LO IN port of the same VST.
  4. Use five 0.25 m MMPX-MMPX cables to connect the following modules:
    1. Connect the REF OUT port of the VST in slots 2 through 3 to the REF IN port of the VDG in slots 4 through 6.
    2. Connect the REF OUT port of the VDG in slots 4 through 6 to the REF IN port of the VDG in slots 7 through 9.
    3. Connect the REF OUT port of the VDG in slots 7 through 9 to the REF IN port of the VDG in slots 10 through 12.
    4. Connect the REF OUT port of the VDG in slots 10 through 12 to the REF IN port of the VDG in slots 13 through 15.
    5. Connect the REF OUT port of the VDG in slots 13 through 15 to the REF IN port of the VST in slots 16 through 17.
  5. Use two 0.20 m SMA-SMA cables to connect the following modules:
    1. Connect the RF OUT port of the VST in slots 2 through 3 to the LONG IN port of the VDG in slots 4 through 6.
    2. Connect the RF OUT port of the VST in slots 16 through 17 to the LONG IN port of the VDG in slots 13 through 14.
  6. Use two 0.30 m MMPX-SMA cables to connect the following modules:
    1. Connect the RF IN port of the VST in slots 2 through 3 to the LONG OUT port of the VDG in slots 4 through 6.
    2. Connect the RF IN port of the VST in slots 16 through 17 to the LONG OUT port of the VDG in slots 10 through 12.
  7. Use two NANOPITCH-MINI HDMI cables to connect the following modules:
    1. Connect the DIO port of the VST in slots 2 through 3 to the DIO IN port of the VDG in slots 4 through 6.
    2. Connect the DIO port of the VST in slots 16 through 17 to the DIO IN port of the VDG in slots 10 through 12.
  8. Use two Cable Retention Bracket to secure the following connections:
    1. Secure the DIO port of the VST in slots 2 through 3.
    2. Secure the DIO port of the VST in slots 16 through 17.
  9. Use two 0.25 m MINI HDMI-MINI HDMI cable to connect the following modules:
    1. Connect the DIO OUT port of the VDG in slots 4 through 6 to the DIO IN port of the VDG in slots 7 through 9.
    2. Connect the DIO OUT port of the VDG in slots 10 through 12 to the DIO IN port of the VDG in slots 13 through 15.
  10. Use two 0.46 m SMA-SMA cables to connect the following modules:
    1. Connect the RF IN port of the VDG in slots 4 through 6 to the RX IF OUT port of the mmWave Radio Head.
    2. Connect the RF OUT port of the VDG in slots 4 through 6 to the TX IF IN port of the mmWave Radio Head.
  11. Use one 1 m MINI HDMI-MINI HDMI cable to connect the DIO OUT port of the VDG in slots 13 through 15 to the DIO 0 port of the mmWave Radio Head.
