DESCRIPTION:

The VIAVI CX100 ComXpert is a lightweight handheld communications service monitor engineered for technicians performing field maintenance, troubleshooting, installation, and verification of tactical, handheld, vehicle-mounted, public safety, and land mobile radio systems. Designed for situations where larger bench-top equipment is impractical, the CX100 combines essential RF measurement capabilities into a rugged portable platform.

The platform is optimized for:

• Tactical military radios
• Land Mobile Radio (LMR)
• Public safety communications
• Utility communications systems
• Transportation radio networks
• Vehicle-mounted radios
• Portable radios
• RF infrastructure maintenance

The CX100 combines multiple test instruments within a single handheld architecture, including:

• Communications service monitor
• Spectrum analyzer
• RF signal generator
• Power measurement
• Frequency measurement
• Modulation analysis
• One-port Vector Network Analyzer (VNA)
• Cable and antenna analysis

allowing technicians to perform comprehensive radio and infrastructure testing from the bench to the field.

Built around the VIAVI OneExpert platform architecture, the CX100 provides a modern touchscreen interface with menu-driven workflows that enable rapid switching between test setups and measurement functions. The instrument is designed to minimize training requirements while maintaining professional-grade RF performance.

A built-in one-port VNA enables:

• VSWR measurements
• Return loss testing
• Cable fault identification
• Antenna system verification
• Feedline troubleshooting

making the platform suitable for both radio testing and RF infrastructure maintenance.

The CX100 also supports remote operation through the VIAVI Mobile Tech application, enabling technicians to control the instrument remotely using a smart device when testing antennas, repeaters, tower installations, and other difficult-to-access equipment.

Designed for demanding field environments, the platform features a MIL-PRF-28800F Class 2 ruggedized enclosure, internal rechargeable battery operation, wireless connectivity options, and compact handheld form factor for deployment across military, public safety, transportation, and utility communications networks.
