NT-OTA 3500A mechanical mixing reverberation chamber
NT-OTA 3500A mechanical mixing reverberation chamber
Summarize
NT-OTA3500A mechanically stirred reverberation chamber provides a statistically uniform electromagnetic field environment, which can be used for radio testing by means of statistical principles to characterize the wireless communication and antenna system performance of Sub6GHz and mmWave band devices, greatly improving the test efficiency compared with traditional OTA test schemes.
Application Scenario
The NT-OTA3500A reverberation chamber adopts horizontal + vertical Z-type mixing paddle and DUT one-dimensional rotary table to ensure the uniformity index of field strength in the test area. The internal space size is large, which can meet the omnidirectional power index test of large-size equipment such as base station antenna, smart refrigerator and TV set.
Test ability:
In terms of test capability, the reverberation chamber can test non-directional RF indicators, such as TRP, ACLR, stray radiation, spectral emission templates, etc.
