Small-sized Anechoic Chamber (3m Method)

Features

  • Exclusively for small-size. Standardized for the purpose offrequent use of EMI/EMS
  • Thin type turntable design (approx. 20 cm) allowing for the flat floor. Also installable within an existing building (height: approx. 3.5 m)
  • In EMI measurement in EMI specification (ALC-3SL/ALC-3S), correlation with actual results is easily obtained as the earth-reflected wave is utilized, as in the measurement at open field test site. EMS specifications (ALC-3W) is suitable to comparative measurement using correction values because of simplified application method.
  • Ferrite radio wave absorber (TFA) is used to the frequency up to 1 GHz. Additional radio wave matching devices are available for the frequency ranging from 30 MHz to 18 GHz.
  • Non-flammable finishing material secures the safety of high-frequency, high-output immunity tests
