System for simulating electromagnetic environments including a network of a plurality of probes

摘要

The invention concerns a system for simulating electromagnetic environments, including a network of emitting and/or receiving probes to test at least one test antenna, channels for connecting the probes to a channel emulator, a signal emitting unit, a signal receiving unit, one of the units being connected to the emulator. The invention is characterized by a switching device having a first measurement position, in which the device connects the emulator respectively to at least one of the probes via the associated channel and connects the other unit to the test antenna, and a second position for calibrating the channels, in which the switching device connects the emulator to the other unit via the associated channel without passing through the network of probes.

1. A system for simulating electromagnetic environments, including:
a network of a plurality of probes for emitting and/or receiving electromagnetic radiations to or from a test point at a distance from the probes in order to test at least one test antenna located at the test point, a channel emulator having a multiplicity of channels, a first signal emitting unit, a second signal receiving unit, one of the first and second units being connected to the channel emulator, characterized by a switching device between the channel emulator and the plurality of probes, wherein the switching device has: a multiplicity of first accesses connected respectively to the multiplicity of channels; a plurality of second accesses connected respectively to the plurality of probes; a third access connected to the other of the first and second units; a fourth access connected to the at least one test antenna a first measurement position for testing the at least one test antenna through at least one channel, in which at least one of the first accesses is connected to at least one of the second accesses and the third access is connected to the fourth access, so that the switching device connects the emulator respectively to at least one of the probes via said at least one associated channel and connects the other of the first and second units to the test antenna; and a second position for calibrating at least one of the channels, in which at least one of the first accesses is connected to the third access, the fourth access is disconnected from the third access and the second accesses are disconnected from the first accesses and from the third access, so that the switching device connects the emulator to the other of the first and second units via said at least one associated channel without passing through the network of probes, the second position being distinct from the first position.
