摘要： A system for testing electromagnetic compatibility of electrical devices includes a plurality of mobile-ground-planes and a fixed-ground-plane. Each of the plurality of mobile-ground-planes is individually customizable to provide a test-fixture for testing a selected instance of an electrical device. The fixed-ground-plane is configured to receive an instance of the plurality of mobile-ground-planes to overlay the fixed-ground plane and form a direct electrical contact between a bottom-side of the instance of the plurality of mobile-ground-planes and a top-side of the fixed-ground-plane. Optionally, the system includes an air-nozzle used to generate an air-gap between the instance of the plurality of mobile-ground-planes and the fixed-ground-plane while the instance of the plurality of mobile-ground-planes is being placed onto the fixed-ground-plane when gas passes through the air-nozzle.

摘要： The present invention discloses a test method and arrangement for testing GNSS signals within a test chamber. The test chamber inner walls are supplied with transmitting antennas supplying simulated satellite signals, originating from a signal generator. Dynamic satellite movements are simulated by interpolating several transmitted signals in order to create a single true satellite transmission signal. All visible satellites are taken into account in order to create simulated GPS signals across the whole virtual sky. Phantom objects may be used near the device under test and the phantom object may be moved or rotated in preset patterns within the test chamber. Radio channel information can be modelled according to several different real-life environments, and also reflections from any surfaces and different multipath options are taken into account in the modeling, and also in the transmission antenna angles towards the device under test. Main application areas of the invention comprise sports watches, health related or any other monitoring devices, or any devices benefiting from the positioning information, also relating to animal applications. The device may be carried or worn by the human user or any other living creature, as a wearable positioning device.

摘要： An apparatus including a chamber that defines an internal cavity therein, adapted to enclose the device under test, and including walls of an inwardly reflective material, rendering the walls reflective to electromagnetic waves, thereby simulating a multi-path environment. Thus, the chamber is a reverberation chamber. At least one moveable object and chamber antenna are arranged in the cavity. A measuring instrument is connected to the device under test and the chamber antenna, for measuring the transmission between them. Further, an improved antenna holder is disclosed, comprising three surfaces of a reflective material, said surfaces extending in planes which are orthogonal in relation to each other and each surface facing away from the other surfaces, and wherein a chamber antenna is arranged on each of said at least three surfaces. Other improvements relate to video surveillance, channel emulation and shielding.

摘要： A radiation signal measurement system for millimeter wave transceivers is disclosed. Embodiments of the present invention utilize a laser to align the laser with an antenna. The transceiver is then moved into the path of the laser to align the laser with the transceiver. The transceiver or antenna orientation is changed such that the transceiver and antenna face each other, in an aligned position. Millimeter wave absorber material is applied to the inside and outside of the testing chamber to minimize reflections and interference from outside sources.

摘要： Disclosed are systems, devices and methods related to scanners that can be utilized for multiple electrical and/or magnetic field measurements at different locations of a radio-frequency (RF) module. In some embodiments, a scanning system can include a miniature probe such as a magnetic probe, a fixture system configured to hold a device under test (DUT) such as an RF module, an operating system configured to operate the DUT, and a measurement system configured to obtain field strength measurements through the miniature probe at different locations of the DUT. Such measurements can yield a near-field distribution over a plurality of selected areas of the DUT, with each of the selected areas being smaller than an overall lateral area of the DUT. In some implementations, such a scanning system can be utilized to facilitate applications such as electromagnetic (EM) shielding designs.
