Abstract: Modular building blocks for building a robotic system, and the method of building the robotic system using the building blocks, are presented. The building block includes a chassis having a first end and a second end, a first connector positioned closer to the second end than the first end of the chassis, either a second connector or a rotational actuator positioned closer to the first end than the second end of the chassis and configured to couple with the first connector, a signal interface on a surface of the chassis, the signal interface including hardware and circuitry for transferring and receiving signals from and to the building block, and a power and control interface on the chassis for receiving power for the building block.

Abstract: A system employing vector signal generator (VSG) and vector signal analyzer (VSA) modules or cards that are configured to test multiple devices under test simultaneously. Each VSG is configured to generate multiple RF test signals and send them to multiple devices under test simultaneously. Similarly, each VSA is configured with multiple signal receiving modules connected to a single controller or memory. Each signal receiving module receives an RF signal from a device under test, converts it to a baseband digital signal, and transmits this digital signal to the VSA's memory. A single RF testing system can employ multiple such VSGs and VSAs, each capable of evaluating multiple devices under test. Each VSG/VSA can further be tuned for operation in discrete or defined frequency bands, which are narrower than those for conventional RF testers, and which can correspond to various wireless standards.

Abstract: A system for parallel radio frequency (RF) testing. The system includes a plurality of signal generators, a plurality of signal analyzers, a data bus connected to the plurality of signal generators, and a controller. The controller has a connection to the data bus so as to be in electronic communication with the plurality of signal generators, and has a plurality of point to point links to respective ones of the signal analyzers so as to be in electronic communication with the plurality of signal analyzers.
