The Mobile RF Test Chamber has been developed for testing RAIN RFID devices using the tools CISC RAIN Xplorer. It is a compact, high-quality RF test enclosure optimized for the frequency band 700 MHz – 6 GHz. The premium multi-layer absorbers provide excellent reflection absorption despite very small dimensions. The measuring chamber is internally shielded and fully lined with multi-layered foam absorbers. The RF-proof shield is realized by a reflective coating. The main access to the measuring room is equipped with RF shielding. The housing and the shielding have separate ground connections. A sliding door is provided for comfortable access. Optionally, a positioner (turntable) can be provided with the measuring chamber. The holder(s) of the measuring antenna is made of RF neutral material.
