Advantages
- Compliance‑ready: Chambers engineered for CISPR/ANSI/IEC/ISO/3GPP/CTIA workflows (NSA/SVSWR/Field Uniformity, Quiet‑Zone metrics).
- Wide frequency coverage: From LF/HF EMC up to mmWave OTA (sub‑THz ready on request).
- Repeatability & traceability: Rigid fixtures, stable absorbers, precise motion systems, and documented acceptance tests.
- Scalable & upgradable: Modular shielding/absorber kits, easy retrofits for new bands or larger EUTs.
- German project execution by EMCO: Local specification support, site survey, logistics, installation, training, and lifecycle service.
Main Features
- Shielding & RF interfaces: Modular steel panels, high‑performance doors, RF honeycomb vents, filtered power and I/O feedthroughs.
- Absorber systems: Ferrite tiles and broadband hybrid absorbers optimized for EMC and microwave/OTA use.
- Positioning & mechanics: Turntables (light to heavy EUT), antenna masts, multi‑axis positioners, CATR reflectors for compact ranges.
- Environmental integration: RF‑filtered HVAC, LED chamber lighting, surveillance cameras, safety interlocks.
- Measurement performance: Designed for NSA/SVSWR, Field‑Uniformity and Quiet‑Zone targets appropriate to the use case.
Typical Applications
- EMC compliance: Radiated emissions/immunity per CISPR/IEC/ANSI, automotive (CISPR 25/ISO 11452), aerospace/defense, medical.
- Wireless/OTA: Antenna/OTA characterization (CTIA/3GPP), 5G FR1/FR2, Wi‑Fi/Bluetooth, GNSS, MIMO/beamforming.
- R&D and production: Antenna patterning, coexistence studies, pre‑compliance, E2E device validation, end‑of‑line checks.
Additional Information
- Turnkey delivery: From requirement capture and chamber layout to on‑site acceptance, documentation and user training.
- Quality & calibration: Support for DAkkS‑aligned measurement chains and periodic verification plans.
- Lifecycle services: Preventive maintenance, absorber health checks, upgrades for new standards and bands.
