| | 7 | Topology is controlled with the [wiki:Documnetation/Topology/aRFControl RF Transceiver Test System] from [http://www.jfwindustries.com JFW Industries] which is a 9 port programmable attenuator based test system. The topology is controlled through the [http://omf.mytestbed.net OMF] based [wiki:Documentation/Services/bInstrumentationControlService Instrumentation AM]. |
