VIAVI CX300 Software Update 3.0.1 for professional radio service

New software release for the VIAVI CX300

Software Release 3.0.1 is now available for the VIAVI CX300 Communications Service Monitor. The update is aimed at users working in professional radio and communications technology, particularly in service, test and diagnostic environments.

The release focuses on new functions, usability improvements and extended measurement and analysis capabilities. It supports more efficient workflows for testing and maintaining radio equipment and communication systems.

Technical context

The CX300 is used as a Communications Service Monitor for professional radio technology. In these applications, fast diagnostics, repeatable measurement workflows and clear visualization of RF and system parameters are essential.

Release 3.0.1 addresses functions that are relevant for service technicians, test laboratories and operators of professional radio systems: protocol support, VNA measurements, cable analysis and automated test applications.

Key updates in Release 3.0.1

The software update extends the CX300 with several practical enhancements:

• New support for the TETRA MS Protocol for professional and mission-critical radio communication applications.
• Improved performance and operation of the 2-Port VNA functions for RF measurement and analysis tasks.
• Smith Chart for visualizing complex impedance conditions.
• Reference Math for extended measurement evaluation.
• New DTF cable tables for additional cable measurement and analysis tasks.

Updated Auto-Test applications

Release 3.0.1 includes updated Auto-Test applications for several radio platforms. The information provided lists support for the following manufacturers and series:

• BK Technologies KNG
• Icom P25
• Kenwood NX300 / NX5000 Series
• L3Harris XL Series
• Motorola APX Series

For service organizations, this can help standardize test workflows, especially when multiple radio types or manufacturers must be checked in operational environments.

Relevance for service, laboratory and test operations

The update is particularly relevant where measurement time, usability and diagnostic depth directly affect daily operations. Improvements to the 2-Port VNA functions and additional analysis tools such as Smith Chart and Reference Math support the evaluation of RF connections, matching conditions and cable paths.

The new and updated functions can help users build more efficient service and test processes and analyze faults more precisely. Licensing details, update procedure and system requirements are not specified in the provided information.
