Verifying O-RAN Radio Units

O-RAN's open architecture demands efficient testing of radio units (O-RUs). Rohde&Schwarz and VIAVI Solutions present a powerful solution that verifies O-RU conformance to O-RAN and 3GPP standards. The joint setup offers automated testing, ensuring O-RU quality across hardware and software releases.

The VIAVI TM500 O-RU Tester emulates the distributed unit (DU), while Rohde&Schwarz signal generators and analyzers handle RF signals. The VIAVI O-RU Test Manager simplifies O-RU conformance testing by automating test configurations and generating reports.

The solution supports both transmitter and receiver tests, allowing users to verify O-RU performance against predefined test cases or custom waveforms. The Rohde&Schwarz signal and spectrum analyzer captures and analyzes transmitted and received signals.

While the solution focuses on O-RU pre-conformance testing, it provides a solid foundation for full 3GPP base station conformance testing. By addressing the unique challenges of O-RAN testing, Rohde&Schwarz and VIAVI Solutions offer a valuable tool for network operators and equipment vendors.
