The Microwave Vision Group (MVG) has introduced the SG Evo, a multi-probe system for spherical near-field antenna measurement and OTA testing particularly suited for large or heavy Devices Under Test (DUT) and high-accuracy applications. Its unique design enables unlimited sampling thanks to a precision positioning mechanism in the arch. This eliminates any tilting of the DUT, consequently avoiding gravitational deflections of the DUT and azimuth positioner. The SG Evo can also be configured with multiple parallel receivers to reduce measurement time, especially effective when testing several frequencies or devices with many potential antenna beam states.
The SG Evo is designed to measure large and heavy antennas such as 5G massive mimo BTS, satellite and ground terminal antennas. SG Evo provides fast and accurate antenna performance test results in record time.
Innovation in the SG Evo boosts the speed and accuracy of original MVG SG systems: the SG Evo 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 modular design scheme of the SG Evo also allows for flexibility in its build: the size of the probe array arch can be decided in accordance with the typical size and weight of the DUT; and the sets of probes can be selected according to the frequencies to be measured – from 400 MHz to 50 GHz.
With these key features in addition to legacy MVG test technology, SG Evo performs highly accurate tests and measurements at rates 10 to 100 times faster than traditional methods.
