DMC-OTA-6G Wireless Test Chamber

 

To minimise path loss and to get best results, these shield boxes can include racking options to incorporate instruments directly at the enclosure.
  • Frequency 700MHz to 6GHz
  • Shielding effectiveness > 70dB
  • 4 DUTs test in parallel
  • High efficient acquisition algorithm for processing the TRP with multiple test probes, instead of adjusting the antenna position by products. Achieve 1dB accuracy
  • Support TX, RSSI, BER, BLER,FER, EVM, RSE and other test indicators
  • Wireless communication with DUT. Avoid the USB impact to the antenna frequency response
  • Manual or RS-232C/remote operation, suitable for automation line;
  • Input AC power: 100-240V AC 50Hz.
