Large Spherical Near-Field Range

Our large spherical near-field test range test chamber, located in our Los Angeles office, measures 6.1 m (20 ft) wide, 6.1 m (20 ft) and 6.4 m (21 ft) high and lined with 0.9 m (36 in.) pyramidal absorber. This chamber can accommodate test articles up to 1.5 m (5 ft) in diameter and 450 kg (1,000 lb) and is capable of low-frequency measurements down to 300 MHz. The system includes a SNF scanner with a 1 m (40 in.) z-linear translation stage.
