Examples

• Systems for OTA Tests/Wireless Tests in Temperature Environments　Constant Temperature RF Anechoic Chamber
  • It is possible to conduct wireless RF performance tests in a temperature environment.
  • Shielding performance → frequency range: 0.5 to 30 GHz, attenuation rate: 60 db or higher.
  • There is no negative impact on peripheral equipment because leaking of radio waves generated by the specimen is prevented.
  • The interior of the RF anechoic chamber can be precisely controlled from low temperature to high temperature.
  • Freezing is prevented by our proprietary insulation technology, which allows the operation of a turntable or positioner without operating restrictions even at low temperatures.

  Controlled temperature range		-40 to +100 °C
  Shielding performance	Frequency range	0.5〜30 GHz *
  	Attenuation rate	60 db or higher*
  Interior dimensions(mm)		W14000×H3000×D7000 *

  * Contact ESPEC for shielding performance and interior dimensions not listed above.

  
• Systems for OTA Tests/Wireless Tests in Temperature Environments　Shielded Box/RF Anechoic Box + Precision Air Supply System
  • It is possible to conduct wireless RF performance tests
    in a temperature environment.
  • Temperature-regulated air from the unit-type temperature supply system is supplied to the RF anechoic box through
    a duct.
  • A box that allows radio wave transmissions is used to keep
    the temperature environment of the specimen constant.
  • You can connect this system to an RF anechoic box/shielded box that you already own.
    * Contact ESPEC in advance to determine if the system can be connected.

  Controlled temperature range		-40 to +100 °C
  Shielding performance	Frequency range	77 GHz
  	Attenuation rate	50 db
  Interior dimensions(mm)		W1200×H1200×D12000 (The interior dimensions can be changed.)

  
• Temperature Environment Wireless Protocol Test System - RF Anechoic Box-Type Low Temperature Chamber
  • Capable of wireless protocol tests in a temperature environment.
  • Ensures an attenuation rate of 60 dB or greater in 4.0 to
    6.0 GHz frequency bands.
  • The interior of the RF anechoic box can be precisely controlled from low temperature to high temperature.
  • Smaller installation area than an RF anechoic chamber to facilitate testing of small communications modules.
