Turn Every Technician into a Network Expert
Troubleshooting increasingly complex HFC networks requires more than a signal meter. Technicians need clear diagnostics, simple workflows, and access to the right network information whether they are at the headend, in the outside plant, or inside a subscriber’s home.
The CGNDP4 cable signal meter works with Hitron ProMeter and HitronCloud® to connect field diagnostics with broader network visibility. Technicians get detailed results directly on familiar smartphones or tablets, while supervisors can gain real-time visibility into what technicians see in the field. Together, these tools help operators identify issues faster, improve first-time fix rates, reduce repeat service calls, and deliver more consistent subscriber experiences.
Diagnose DOCSIS 4.0 Networks with Confidence
Validate next-generation HFC networks with a diagnostic platform supporting DOCSIS 4.0 as well as DOCSIS 3.1, 3.0, 2.0, and 1.1. Full-frequency spectrum support up to 1.8 GHz and switchable upstream capabilities help technicians troubleshoot today’s networks while preparing for evolving DOCSIS architectures.
Business Value
- Support DOCSIS 4.0 network evolution
- Standardize testing across multiple DOCSIS generations
- Improve network validation and troubleshooting
Find Network Problems Faster with Advanced Diagnostics
Give technicians detailed upstream and downstream visibility with spectrum analysis, channel scans, MER, QAM analysis, OFDM/OFDMA diagnostics, ingress and noise detection, pre-equalizer analysis, IQ constellation, Ping, Traceroute, and more. Hitron’s SnapShot capability captures network conditions at a specific point in time for deeper analysis.
Business Value
- Isolate network issues faster
- Reduce troubleshooting time
- Improve first-visit resolution
Put Powerful Diagnostics on the Technician’s Mobile Device
The CGNDP4 pairs with the Hitron ProMeter mobile app for iOS and Android, displaying detailed diagnostic results on smartphones and tablets technicians already know how to use. The app-driven workflow eliminates the need for dedicated display hardware while simplifying operation and technician training.
Business Value
- Simplify technician workflows
- Reduce training requirements
- Provide a familiar, intuitive user experience
Validate Multi-Gig Performance in the Field
Test whether the network can actually deliver the performance expected from next-generation services. The CGNDP4 includes a 10GbE interface and Hitron ProMeter SpeedTest capabilities measuring speeds above 9 Gbps, enabling technicians to validate performance over coax and through Ethernet-connected CPE.
Business Value
- Validate multi-Gig service performance
- Identify performance bottlenecks
- Verify service before completing the job
The Next Generation of a Trusted Field Diagnostic Platform
The CGNDP4 builds on the proven design of the Hitron CGNDP3, a field diagnostic platform used by dozens of service providers. It carries forward the practical, technician-focused approach operators already rely on while extending the platform for the next generation of HFC networks. With support for DOCSIS 4.0, spectrum up to 1.8 GHz, 10GbE testing, and advanced diagnostics, the CGNDP4 gives service providers a proven foundation for preparing their technicians and operations for DOCSIS 4.0.
