Shielded RF Test Enclosure – Portable, 80 dB Isolation: 5247 | ETS-Lindgren
The ETS‑Lindgren 5247 is a self‑contained, portable shielded test cell for wireless device OTA performance measurements. It leverages the same high‑performance shielding and door technology used in full certification chambers. The interior is RF absorber lined and ships with a dual‑polarized horn antenna. EMCO Elektronik provides design support, integration, and measurement best practices tailored to your lab or production line.

Benefits
- Portable footprint: roll‑about casters enable easy relocation across benches and lines.
- High shielding: typical >80 dB RF isolation for stable, repeatable OTA results.
- Measurement fidelity: absorbers minimize reflections and cavity modes.
- Fast antenna swaps: quick‑change ceiling panel.
- Rich I/O: pre‑populated bulkhead with SMA, N, filtered D‑Sub, fiber feedthrough, ground stud.
Key Features
- RF absorbers: tapered wedges on walls, pyramidal floor; lossy foam at antenna—optimized for bands of interest.
- Dual‑polarized horn: linear and, with optional hybrid, circular polarization; standard coverage 700 MHz–6 GHz, typically flat response from 2–6 GHz.
- Door/shielding: knife‑edge with compressible finger stock; two‑point latching and single‑handle operation.
- Feedthrough panel: 1× SMA, 3× Type‑N, 1× filtered 25‑pin D‑Sub, six‑line fiber feedthrough, 1× ground stud; separate quick‑change antenna panel.
