Abstract
Some embodiments include a system for simulating electromagnetic environments that includes a channel emulator having a plurality of outputs, each output associated with a different operational path. Each operational path has a power amplifier, an antenna and a first coupling mechanism. The power amplifier is coupled to an output of the channel emulator. The antenna is in communication with a test region of the apparatus. The first coupling mechanism simultaneously couples power to the antenna and to a first measurement path when the operational path is coupled to the test region, so that a calibration state of the operational path can be determined and adjusted without interruption of a signal coupled to the antenna in the operational path.
