SG Evo multi-probe spherical near-field antenna
Microwave Vision Group (MVG), has launched the SG Evo, a multi-probe spherical near-field antenna measurement system designed for heavy DUTs and high accuracy applications in satcom, telecom, aerospace and more. Innovation in the SG Evo boosts the speed and accuracy of original MVG SG systems.
This new system incorporates oversampling positioning within the arch, eliminating the need to tilt the device under test (DUT) when oversampling and consequently avoiding gravitational deflections of the DUT and azimuth positioner, even when testing heavy DUTs. Additionally, the SG Evo can be configured with multiple parallel receivers, dramatically reducing measurement time, especially when testing a large number of frequencies or devices with many potential antenna beam states.
The SG Evo also has a modular design scheme which allows for flexibility in its build: the size of the probe array arch and the positioner model can be decided in accordance with the typical size and weight of the DUT; and sets of probes can be selected according to the frequencies to be measured, from 400MHz to 30GHz.
The SG Evo is useful for a wide spectrum of applications and at all stages of testing, from initial prototype testing in R&D to final validation testing of fully integrated devices in production. Finally, both passive antenna measurement and OTA tests are applicable in the SG Evo.
Philippe Garreau, CEO of MVG, said: “The over-sampling carried out by the array arch in the SG Evo is new, patented MVG technology designed with the intention to mitigate movement of devices under test, for even more speed and accuracy in test results. We are excited to see how it will add value to our customers’ innovations.”
