In light of ever-evolving standards, test solutions need to support higher frequencies, wider bandwidths, and new physical layer capabilities. Thanks to the much faster, more reliable, and near-instant connections that come with the 5G, we now see a variety of innovative and comprehensive mobile wireless communication applications every day. Base stations must now pass new conformance tests to ensure they deliver on their promises. Performing conformance testing is an important part of the base station lifecycle, which requires a thorough understanding of 3rd generation partnership project (3GPP) specifications.
This paper discusses 5G NR Release 16 base station transmitter conformance testing requirements and the specific challenges that arise in millimeter wave (mmWave) frequency testing. We will also discuss how to stay compliant with standards using the new designs in Keysight signal analysis solutions, when testing your base station transmitters.
