Full 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.
