Test principle


Test main equipment


1、Far-field test system
Henxin Technology has a large microwave chamer for far-field test, the chamber contains: shielding system, wave absorbing material, ventilation, constant temperature, dehumidification equipment and antenna far-field test system.



2、Near-field test system
Henxin Technology adopts French SATIMO 128 probe, which makes the near-field test system have greater advantages. At present, the 128 probe antenna near field test system is the only test system recognized by the three operators for testing DAS and concealment antennas.

5G OTA testing

Test principle


5G OTA test is based on the far-field passive test by upgrading the test system, including turntable, control software, test software, post-processing software, source antenna drive control system, etc. to achieve the test purpose.




Test system advantages


1. Optical fiber, power supply, network cable and other interfaces are equipped to support continuous rotation
2. Frame depth up to 5m
3. High degree of automation
4. Transceiver distance 38.5m, meet the interpolation loss between equipment to the spectrum meter in about 80dB
5. Testing items and precision meet the requirements
6. The automatic test of OTA is realized
7. High testing efficiency, simple testing system, easy to operate.
