EMITE and Anritsu Integrate MT8000A gNodeB Emulator with H300 CATR for 5G OTA Testing

October 2, 2019

Anritsu and EMITE announced that the Anritsu MT8000A test instrument, an integrated one‐box test set for testing 5G NSA and SA at sub‐6 GHz and mmWave frequency ranges, has been successfully integrated and used in combination to the EMITE H300 CATR 5G OTA Test System to test 5G OTA figures of merit. The combination of H300 + MT8000A enables simultaneous sub‐6 GHz and mmWave bands OTA measurements and beamforming tests using call connections specified by CTIA, 3GPP and PTCRB with automated reporting and pass/fail evaluation.

A number of NR NSA devices have been tested in combination with Anritsu MT8821C with less than 0.5 dB STD differences. The benchmarking tests used different 5G signal generation and analysis instruments with the state‐of‐the‐art H‐Series CATR OTA Test System by EMITE. With excellent 15 um peak‐to‐peak manufacturing accuracies, the modified‐design serrated‐edges reflector and hybrid feed‐source, the H‐Series can provide simultaneous operation for sub‐6 GHz and mmWave frequencies using three different test methods, Direct Far Field, Near to Far Field Transformation and Indirect Far Field Compact Antenna Test Range from 0.6 to 110 GHz within a 30 or 60 cm Quiet Zone. Layer‐2 OTA throughputs for a 100 MHz 2x2 NR channel achieved 817 Mbps for some devices, representing 100 percent of the maximum expected throughput for the employed slot‐map.  

“We have observed quite a stable operation for 5G OTA using Anritsu gNodeB emulators, and our customers are happy, so we are happy. The combination of the stable signaling, our simultaneous FR1+FR2 frequency range coverage, a 60 cm QZ and a climatic enclosure puts our H‐Series Test Platforms in an unbeatable situation in the market,” said Prof. David A. Sanchez‐Hernandez, CEO of EMITE.
