    Transceiver Test System for Radio-to-Radio Testing with Full Fan-out DesignFull Fan-out Transceiver Test Systems for Radio Testing

    A full fan-out transceiver test system is constructed as a fully meshed matrix. There is a path between every pair of ports. Every path has its own individually controlled programmable attenuator. This construction is ideal for testing radio-to-radio communication because every path can be set to a unique dB setting.  The main cost driver for this design is the number of individually controlled attenuators.  The number of attenuators increase as the number of ports increase. 6 Port Design: 6 fully meshed ports with 15 paths and 15 attenuators 8 Port Design:  8 fully meshed ports with 28 paths and 28 attenuators 12 Port Design: 12 fully meshed ports with 66 paths and 66 attenuators 16 Port Design: 16 fully meshed ports with 120 paths and 120 attenuators 32 Port Design: 32 fully meshed ports with 496 paths and 496 attenuators Each path through the matrix has its own individually controlled programmable attenuator. The programmable attenuators allow the transmission from one port to be received at all other ports at different signal levels. This allows the simulation of a network where each device has a different distance (i.e. attenuation setting) from all other devices. The attenuators can be remotely controlled to simulate static or dynamic environments.

    4 Port Full Fan-out Transceiver Test System Example

    Below are two diagrams. The left diagram shows how all ports are connected to each other. The right diagram shows the attenuator addressing for each path. A full fan-out 4 port transceiver test system requires a total of 6 programmable attenuators. Each of the programmable attenuators can be individually controlled. The full fan-out configuration allows for each path to be set to its own unique attenuation setting. A radio connected to port #1 can transmit a signal to radios on ports #2, 3, 4 at different signal levels simultaneously. Our latest generation firmware allows for the attenuators to be faded individually or grouped together and faded as a group.

    Custom Models

    The models listed in the above table showcase some of our standard transceiver test systems. However, most of JFW's test system business involves custom designed models. JFW does not charge NREs for custom models. We encourage you to email us your specific requirement at sales@jfwindustries.com. We will respond with a ROM (rough order of magnitude) quote in 1-2 days.

    Remote Commands

    The transceiver test system models are available with Ethernet/Serial remote control.  Our current generation of Ethernet/Serial firmware is called 3.x.x firmware. It features easy to use ASCII formatted remote commands. Use our Ethernet Test Box to demo the 3.x.x firmware.

    Test Software

    JFW provides a GUI test program with all Ethernet and RS-232 controlled test systems. The test software for transceiver test systems has all of the remote commands built in for easy testing. In addition to the remote commands, the GUI test program has additional functionality such as keypress, handover, and indefinite handover. Several of our sample test programs are available online.
  • Hub Fan-out Transceiver Test Systems for Radio Testing

    JFW model 50PMA-073 Hub Fan-out Transceiver Test SystemHub Fan-out Transceiver Test Systems for Radio Testing

    A hub fan-out transceiver test systems is constructed as a star matrix with all ports connected through a central hub. The star configuration limits the number of paths in the matrix to be equal to the number of ports. This type of construction allows for radio-to-radio communication testing. The attenuators can be remotely controlled to simulate static or dynamic environments. With the hub configuration, there is a single programmable attenuators between the port and the hub. Two 4 port example block diagrams are listed below the table. The hub fan-out design is the most basic of JFW's transceiver test systems. It is also the least costly since it uses a minimum number of internal RF components to construct the matrix. By including RF switches into the construction, you may have multiple hubs. Each port will have an RF switch that is used to select between hubs. The isolation of the switches allows the hubs to act as separate networks.

    4 Port Hub Fan-out System w/ 1 RF Hub

    Below are two diagrams. The left diagram shows how all ports are connected to each other. The right diagram shows the attenuator addressing for each path. Each port has its own individually controlled programmable attenuator. A signal transmitted into port #1 is received at the other ports at the following signal levels: Rx at Port #2 = (Tx into Port #1) - (Attenuator #1) - (loss of Hub) - (Attenuator #2) Rx at Port #3 = (Tx into Port #1) - (Attenuator #1) - (loss of Hub) - (Attenuator #3) Rx at Port #4 = (Tx into Port #1) - (Attenuator #1) - (loss of Hub) - (Attenuator #4) Each programmable attenuator in this example can be varied from 0-127 x 1dB to achieve dynamic RF signal fading between ports. The RF hub is designed with an internal star configuration. This star configuration allows all ports to be simultaneously connected to each other with equal port-to-port loss.

    4 Port Hub Fan-out System w/ 2 RF Hubs

    The below block diagram shows an example of a 4 port hub test system with two RF Hubs. The two RF hubs are used to create two isolated groups of radios. Each port can be connected to either hub by setting the 1P2T RF switches. Once connected to a hub, each programmable attenuator can be varied from 0-127 x 1dB to achieve dynamic RF signal fading between ports.

  • Limited Fan-out Transceiver Test Systems for Radio Testing

    Limited Fan-out Transceiver Test Systems for Radio Testing (4)

    JFW model 50PMA-116 Limited Fan-out Transceiver Test Systems for Radio TestingLimited Fan-out Transceiver Test Systems for Radio Testing

    The limited fan-out transceiver test system is constructed as a reduced mesh matrix. A port connects to only X number of its neighboring ports. The number of its neighboring ports can vary depending on the application. By reducing the number of internal paths through the matrix, the size and cost of the test system is reduced. The reduced number of internal paths allows us to offer a greater number of ports. More ports means a greater number of radios to be tested simultaneously. The programmable attenuators can be remotely controlled to simulate static or dynamic environments. In the configuration column of the below table, we use the term LC to describe the number of neighboring ports each port is internally connected. 16 Port LC8: 16 Ports with each port connected to its 8 neighboring ports 32 Port LC16: 32 Ports with each port connected to its 16 neighboring ports 48 Port LC16: 48 Ports with each port connected to its 16 neighboring ports The reduced mesh is our latest type of test system to be added to the JFW website.

    Limited Fan-out Mesh Vs. Full Fan-out Mesh

    The left block diagram is a 12 Port LC8 design. Each port is connected to its eight neighboring ports. The four upper neighboring ports and the four lower neighboring ports. A 12 Port LC8 design requires 48 programmable attenuators. The right block diagram is a full fan-out 12 port mesh which requires 66 programmable attenuators. The limited fan-out design requires 27.27% fewer programmable attenuators than its full fan-out counterpart. This results in the limited fan-out design costing less and being physically smaller while still having the same number or ports. The reduction of internal components becomes even greater as the number of ports is increased.
