VIAVI OneExpert ONX-630 DOCSIS 3.1 CATV Analyzer

OneExpert ONX-630 DOCSIS 3.1 CATV Analyzer with Sweepless Sweep, SWX, TSX

The OneExpert ONX-630 is a professional CATV field analyzer configured for DOCSIS 3.1 network testing with advanced sweep and RF analysis capabilities. The enabled Sweepless Sweep functionality, combined with SWX and TSX software packages, supports continuous forward and reverse sweep measurement without service interruption, addressing modern hybrid fiber-coax and distributed access architectures.

DOCSIS 3.1 and OFDM Measurement Capabilities

• DOCSIS 3.1 support with OFDM channel analysis
• 32×8 bonded channel measurement capability
• RF level, MER, and spectral analysis across downstream and upstream paths
• Designed for evaluation of high-capacity cable modem and node performance

Sweepless Sweep Architecture (SWX)

• Sweepless forward sweep operation without external sweep transmitters
• Continuous measurement methodology reducing network disruption
• Support for distributed and node-based sweep environments
• Alignment workflows compatible with modern CATV plant designs

Forward and Reverse Sweep Testing (TSX)

• Forward sweep analysis for downstream path verification
• Reverse sweep and reverse sweepless sweep for return path characterization
• Ingress visibility and return path alignment support
• Measurement tools aligned with DOCSIS 3.1 upstream requirements

Hardware Interface and System Architecture

The platform integrates a modular CATV hardware interface with dual coaxial RF ports, Ethernet connectivity, USB interfaces, and Bluetooth support. Software functionality is enabled directly on the instrument and reflected within the system configuration, allowing consolidated testing across RF, DOCSIS, and sweep domains using a single handheld platform.

Operational Applications

• DOCSIS 3.1 cable network installation and turn-up validation
• Forward and return path sweep alignment in active networks
• Maintenance and troubleshooting of CATV RF and DOCSIS performance
