Multi-probe Systems

SG Evo

400 MHz - 50000 MHz

The SG Evo is 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.

ROTATING ARCH MECHANISM

Highly accurate measurements by minimizing movements of the DUT
Unlimited oversampling

FREQUENCY RANGE

400 MHz – 50 GHz and more*
*Customizable with a selection of seven types of precision probes covering the 400 MHz - 50 GHz range

MULTI-PROBE ARRAY COMBINED WITH MULTIPLE SIGNAL RECEIVERS

With this option, take the full benefit of your multi-probe array configuration; reach extremely fast measurement speeds from 10 to 100 times faster than in a Compact Antenna Test Range (CATR)

OPTIMIZED REAL ESTATE

Multi-probe near-field measurement technology requires a smaller footprint than far-field ranges or CATR

EXTENSIVE MEASUREMENT CAPABILITIES

OTA testing or antenna measurement
Principle cuts, 2D and 3D patterns
Functional testing
Antenna parameters: radiation pattern (omni, toroid, narrow beam, multi-beam), beam peak, beam width, front to back ratio, cross polar discrimination, side lobe levels, gain, directivity, efficiency, TRP, TIS, EIRP and EIS
