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.

Abstract: Methods, tests systems and computers for controlling power delivered to a test volume are provided. According to one aspect, an electromagnetic test system has at least one operational path having a channel emulator output, an amplifier, an attenuator and an antenna. A method includes, for a given desired output power level, C, setting a channel emulator output power to a power level B, and setting the attenuator to a setting A, such that C is a function of B and A. In such embodiments, the attenuation A may be calculated based on an upper limit output power of the channel emulator and the desired output power C.

Abstract: In some embodiments, an electromagnetic measurement system to perform radio frequency, RF, downlink testing of a device under test, DUT, in a chamber is provided. Exterior to the chamber is an emulator core configured to introduce an impairment in each of at least one transmit signal to produce at least one impaired signal for each of at least one emulated channel. Within the chamber, for each of the at least one emulated channel, an up-converter is configured to up-convert an impaired signal of the emulated channel to produce a radio frequency, RF, signal.
