ANTENNA MEASUREMENT SYSTEMS
COMPACT RANGE
Compact Ranges replicate large plane waves at range lengths that are much shorter than possible on a conventional far-field range. A parabolic reflector transforms the spherical wave from the feed into a plane wave at the test antenna aperture. Compact Ranges are available in almost any size for the entire microwave and millimeter wave frequency bands.
The edges of these reflectors are shaped as serrations, with a design that
directs edge diffraction away from the quiet zone. Serration size increases
as the lowest operational frequency decreases.
The rolled edges of these reflectors minimize the generation of edge diffraction.
Edge size increases as the lowest operational frequency decreases.
SINGLE-PROBE SYSTEMS
Mini-TScan is a fast and ultra-accurate planar near-field scanner with the latest motor drive and encoder technologies. It is designed to meet the need to measure small directive antennas at high millimeter wave frequencies with speed and accuracy. Rapid acceleration of the linear motors for stepped and continuous mode operation optimizes the performance and cost of the scanner. Excellent manufacturing precision combined with direct readout high resolution linear encoders and careful alignment ensure unrivaled mechanical positioning accuracy and planarity.
µ-Lab is suited for the collection of far-field and near-field electromagnetic data of chips and miniature antenna assemblies in the millimeter waveband. It is the ideal measurement system for testing M2M devices using WiGig technology. The extra-wide door on this compact anechoic chamber enables easy access and mounting of the DUT. µ-Lab is a portable turn-key system that can be moved to any preferred location. MVG’s 959 Spectrum software complements the µ-Lab for complete data acquisition and analysis.

RADAR CROSS SECTION COMPONENTS
ORBIT/FR pylons are stationary metal target-support structures designed for low RCS. Their shapes, sizes and construction specifications are determined by requirements such as maximum target cavity size, minimum rotator size, and target size and shape.
String reel target manipulation systems are used to support targets for low frequency Radar Cross Section (RCS) measurements. Three sizes of string reel positioners are used to handle various loads ranging from scaled models up to full size targets. A typical application requires 3 – 16 string reel positioners.
MULTI-PROBE SYSTEMS
StarLab is the ultimate tool for antenna pattern measurements
in laboratories and production environments where space is
limited, cost is critical and the flexibility of a portable system is
required .
- Antenna Measurement System for 5G test applications frequency range from 650 MHz to 50 GHz
- It has a typical dynamic range of 50 dB and is designed for DUTs measuring up to 45 cm.
- compliant with the standards specified for CTIA certification of wireless devices.

Starwave, is composed of one or several (up to seven) PWG(s) attached at a 90° angle to a vertical disk, which rotates. In front of the disk, an electromagnetically transparent mast is mounted on an azimuth positioner to support and rotate a DUT. The interface used between the mast and the DUT depends on the device, with the possibility of inserting a chair for a person holding a device

The SG Evo is a multi-probe system for spherical near-field measurement and OTA testing, particularly suited for large DUTs and high accuracy applications. It 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. The SG Evo can be configured with multiple parallel receivers, to reduce measurement time especially when testing multiple frequencies or devices with many potential antenna beam states.

SG 24 is ideal for the OTA testing of
mobile device conformance at high throughput or high
frequencies, particularly for LTE, WiFi 802.11a and WiFi
802.11n protocols. It offers a measurement speed up to 3
times faster and a considerably higher dynamic range in
passive antenna measurement mode than the previous
version. Available in 3 sizes, with the standard and large
models CTIA certifiable.
SG 32 is a smaller version of the SG 64, with 31 probes (+ 1
reference channel). Two models are available: the SG 32 – 18
GHz, and the SG 32 – 6 GHz. Both have the capacity to switch
between the N-PAC for antenna measurements and the Radio
Communication Tester for OTA measurements. SG 32 can
perform both CTIA comparable TRP and TIS measurements.
The most accurate solution for testing antennas and wireless devices: SG 64 has been developed to measure stand alone antennas or antennas integrated in subsystems. It is also ideal for CTIA certifiable measurement facilities.
Ideal for very large antenna measurements. SG 128 is a bigger version of the SG 64 with 127 probes (+1 reference channel) and is particularly adapted to the measurement of BTS antennas.
StarMIMO provides flexible, fast and efficient end-to-end testing
of MIMO devices using 4G/LTE technology in a controlled
realistic RF environment. The characterization of the
performance of the device is complete in a single measurement.
StarMIMO is a major asset in the design cycle and product
validation of mobile devices.
The AeroLab is a multi-probe Near-Field measurement system particularly designed to measure radomes of commercial aircrafts.
SG 3000 systems are dedicated to full-scale vehicle antenna measurements and OTA testing.The system configuration can be adapted to meet specific needs and to fit your installation:different arch sizes can be designed, and its structure can be fixed (F) or mobile (M) allowing it to be either permanently installed or moved into an existing anechoic chamber. The rotation of the DUT is controlled by a high precision positioning system enabling discrete and/or continuous on-the-fly measurements.
Similar to the StarBot 4200, the StarBot 4300 is a portable test system designed for antenna testing of aircrafts or vehicles in-situ. Improving upon its predecessor, in addition to the high measurement flexibility for radar testing in the nose of an aircraft, its full robotic system and 6 positioning axes enable it to measure antennas anywhere on an aircraft (or vehicle): top, bottom, nose, tail, wings, etc. The StarBot 4300 is designed to characterize antennas without displacing the device under test and without enclosure in an anechoic chamber. It is the ideal spherical near-field antenna test system for extra large devices.
