Anechoic Chamber(10m Method)
Features
- Qualified for various registrations (FCC filing, VCCI registration,DAR, NVLAP, A2LA, and NATA authorizations)
- Mainly composed by ferrite radio wave absorber (TFA).Wide-ranged radio wave absorbency is available in combinationwith radio wave matching devices.
- Barrier-free doors allowing for easy transportation of large-sized devices.
- Standard-equipped storage room for amplifiers for the use in the immunity test.
- Applicable to large-sized devices (maximum specification: a turntable of 10 m in diameter/capacity of 20 tons).
- GP-IB controllable attached facilities allowing for automatic instrumentation
in a short time.
- Additional underground pit construction available for installing counter devices especially in the measuring test of communication equipment (optional).
