5G mmWave OTA Test Environment For Accurate Results

It enables simplified terminal mounting/dismounting and meets the 3GPP RF/RRM Conformance Test recommendations

5G mmWave (FR2) services are expected to become gradually more widespread, especially in developed economies. Consequently, future development and certification testing of 5G mmWave terminals is expected to become more active.

This requires the mmWave terminals to be tested in an OTA environment, but, due to the mmWave and OTA characteristics, obtaining reproducible test results is difficult unless the test terminal is mounted in the test equipment at the same position each time. As a result, not only must terminal mounting/dismounting be easy, but a highly reproducible mounting position should also be present for obtaining good measurement results.

Moreover, accurate results will not be obtained if the best Alignment Option cannot be selected according to the terminal design and especially the mmWave antenna position. 

To meet these challenges, the MA8179A-AK011 DUT Holder has been developed by Anritsu Corporation. Besides simplifying test-terminal mounting/dismounting and maintaining accuracy, the MA8179A-AK011 has been developed as a DUT Holder for the CATR Anechoic Chamber MA8172A to implement a single compact jig supporting the DUT (Device Under Test, e.g. terminals – smartphone or tablet) positions and orientations specified by the 3GPP Alignment Option 1/2/3. Additionally, it satisfies the Quality of Quiet Zone recommendation for the 3GPP RF/RRM Conformance Test. 

Features

• Full support for Alignment Option 1/2/3
• Easy DUT/terminal mounting/dismounting in the test chamber
• Repeatable high accuracy mounting of the test terminal in the test chamber
• Robust engineering-plastics construction assures excellent durability with minimum impact on signals

The DUT Holder MA8179A-AK011 is built into the CATR Anechoic Chamber MA8172A, which meets the 3GPP RF/RRM Conformance Test recommendations, as a fixed jig for test terminals and is mounted on the Positioner MA8179A to auto-control the test-terminal position.

Designed especially for the Radio Communication Test Station MT8000A / New Radio RF Conformance Test System ME7873NR, the OTA chamber has excellent compatibility with 5G mmWave test equipment.
