H300 web


The EMITE H300 5G OTA Test System comprises a medium-size anechoic chamber, a Compact Antenna Test Range (CATR) with a 100cm x 100cm precision reflector, a lateral-positioned tower and feed antenna for the frequency range 3 to 40 GHz, a 3D AuT/DuT fully-automated 0.03º-accurate positioning system for up to 8kg DUTs with a 30cm quiet zone (can be extended to 60cm) and an additional direct feed antenna for the range 600 MHz to 3 GHz. Capable of testing beamforming and 5G signaling Key Performance Indicators, it is the only OTA test system in the market capable of testing FR1+FR2 bands combinations in a simultaneous manner. With unheard-off reflector-manufacturing accuracies, which reflect into extremely good phase accuracies, the H300 can be connected to a gNodeB emulator for active OTA measurements of 5G devices. Extensions to 67 and 110 GHz are available. With a variety of Operating Systems at the 5G UE, time-domain uplink and downlink FTP/TCP/UDP Throughput and latency measurements are also readily available.

 

The H300 OTA CATR + DFF + SNF Test Range provides complete 3D performance assessment for 5G devices and antennas from 0.6 up to 110 GHz, capable of supporting 5G Sub-6 GHz (from 600 MHz to 6 GHz) and mmWave (24 to 110 GHz) standardized OTA testing in accordance to 3GPP TR38.810, TR37.842 and TR38.101. Aerospace-used technology is built into our H300 test range. With serrated reflectors providing unique 15µm peak-to-peak roughness in 30 cm quiet zone and high accuracy 0.03° positioners, with both roll over azimuth and roll over elevation. the H300 is undoubtedly a best-in-its-type chamber, and the only one in the market capable of testing FR1 Sub-6 GHz and FR2 mmWave frequencies in a simultaneous manner.

Additionally, an optional climatic enclosure allows for 5G OTA testing under controlled temperature (from -40 to 90°C) and humidity (from 10% to 98% RH) conditions.


H series connection setup

In addition to the climatic control ad variation for the 5G OTA tests, other unique features include a 15 μm peak-to-peak reflector surface roughness, which leads to uniquely low quiet zone ripple, carbon-loaded polystyrene absorbers for extreme durability, roll over azimuth and elevation over azimuth for a DuT max load of 8 kg, typical accuracies 0.03° with standard backlash 1 to 6 arc min and a unique wide frequency band coverage from 600 MHz to to 110 GHz.
