ETS-Lindgren's Model 2115CR Medium Duty Multi-Axis Positioner is designed to provide smooth rotation of a test object in both theta and phi axes. Typically the model 2115CR is used in systems that measure spherical antenna patterns and total effective radiated power of wireless devices, with MAPS units currently in operation at several CATL labs. Options include the SAM Phantom (head) and ETS-Lindgren's Positioning Controller with GPIB and EMQuest™ Software.

Key Product Information


​The model 2115CR is constructed with low reflective dielectric materials to minimize RF obstruction or distortion, and was designed to minimize EMI noise and offer minimal physical obstruction to RF fields. Motor units contained in RF-shielded enclosures and are designed to be placed below the absorber. Signal lines from motor to the optional positioning controller are fiber optic.
