SYSTEM AND METHOD FOR CALIBRATION AND MONITORING OF AN ANECHOIC BOUNDARY ARRAY RF ENVIRONMENT SIMULATOR

摘要

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.

1. A system for simulating electromagnetic environments configured to determine a calibration state of each of at least one operational path, each of the at least one operational path having an antenna in communication with a test region, the calibration state of an operational path being determined without interruption of a portion of a power amplifier output signal coupled to the antenna, the apparatus comprising:
a channel emulator having an output for each operational path; each operational path including:
at least a power amplifier having an input coupled to an output path of the channel emulator, the power amplifier having an output signal;an antenna in communication with the test region and configured to receive a first portion of the power amplifier output signal; anda first coupling apparatus having an input receiving an output signal of the power amplifier and at least two outputs and being configured to simultaneously couple the first portion of the power amplifier output signal to the antenna and a second portion of the power amplifier output signal to a first monitoring path when the operational path is being used to test a device in the test region, so that a calibration state of at least a portion of the operational path can be determined without interruption of the first portion of the power amplifier output signal coupled to the antenna.
