Model 3100 Wireless Test Lab

Industry-leading measurement accuracy in a compact space.

The Model 3100 is the smallest chamber available on the market that meets the certification requirements of the CTIA Test Plan for Mobile Station Over the Air Performance. The shielded chamber is a 10 foot (3 meter) cube. The Model 3100 can be installed in rooms with a 10 foot (3 meter) ceiling height.

In spite of its small size, the quality of the electro-magnetic field is excellent and far exceeds the performance of much larger chambers. The secret to the Model 3100's high quality electromagnetic field is its distributed axis positioning system. This allows the handset to be supported on a block of low density styrofoam, avoiding 'gravity vector' issues, and minimizes the interaction of the test device and the positioning equipment. Typical ripple in the quiet zone is less than ±1.5dB and the measurement uncertainty contribution is typically less than 0.35dB.
