Anritsu Corporation announced the launch of its DUT Holder MA8179A-AK011 to increase usability of its CATR Anechoic Chamber MA8172A.
Anritsu has developed the MA8179A-AK011 as a DUT Holder (jig) for the 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 both satisfies the Quality of Quiet Zone recommendation for the 3GPP RF/RRM Conformance Test, as well as simplifying test-terminal mounting/dismounting in the test chamber compared to earlier jig designs. The accuracy of the mounting enhances measurement and positional reproducibility.
5G mmWave (FR2) services are expected to become gradually more widespread, especially in developed economies, such as North America and Japan. Development and certification testing of 5G mmWave terminals is expected to become more active.
mmWave terminals must be tested in an OTA environment. Due to the mmWave and OTA characteristics, obtaining reproducible test results is difficult unless the test terminal is mounted in the test equipment at exactly the same position each time. As a result, must terminal mounting / dismounting should be easy and a highly reproducible mounting position is also a key point in obtaining good measurement results.
Anritsu said engineers will not get accurate results if the best Alignment Option cannot be selected according to the terminal design and especially the mmWave antenna position. The DUT Holder MA8179A-AK011 will derive result in a single product and facilitates the introduction of mmWave terminals to the market.
