VIAVI OneAdvisor 800 (ONA-800A) Cell Site Test Platform
The VIAVI OneAdvisor 800 ONA-800A is a handheld modular test platform for cell site technicians. It was designed to cover fiber, RF, and CPRI/Ethernet testing in one device so a single tool can handle the many checks involved in building and maintaining 4G and 5G sites. It guides the technician through each job configures tests automatically gives pass/fail results and produces a single closeout report helping contractors and carriers complete work accurately and consistently.
Key Features VIAVI OneAdvisor 800
- All-in-one cell site testing: fiber, RF, and CPRI/Ethernet testing from one platform
- Test process automation: automatic test configuration, built in guidance, and pass/fail results with a single closeout report for every site
- Plans to carrier specifications: run complete test plans precisely to the service provider requirements
- Modular design: the ONA-800A mainframe with display accepts plug in modules and software options so it can be set up for your work
- Cable and antenna analysis (CAA): cable and antenna sweeps (such as the CAA06MA) to verify feed lines and antennas
- Spectrum analysis (SPA): spectrum analyzer modules (such as the SPA06MA-O 9 kHz to 6 GHz) with optical hardware for RF over CPRI
- Fiber testing: OTDR options in singlemode or quad configurations fiber inspection (FiberChek) and a power meter and VFL module
- Wireless analysis options: interference analysis, route map, gated sweep spectrum, TDD auto gated spectrum, real time spectrum analysis, and over the air analysis for LTE and 5G NR plus GNSS
- CPRI and Ethernet testing: CPRI/eCPRI and Ethernet tests up to 25G through software options
- Connectivity: optional Bluetooth and Wi-Fi and Smart Access Anywhere (SAA) for remote support and coaching of field technicians
- Power and portability: an AC/DC power adapter and an optional power expansion module (extra lithium ion battery)
- Field accessories: a backpack for RF walk testing, back cover, harness, and carrying cases
- Flexible bundles: offered in many pre configured bundles combining CAA, OTDR, spectrum analysis, FiberChek, and RFVision
Typical Applications
- 5G, LTE and small cell site installation and maintenance
- Cable and antenna verification and fault location
- RF spectrum monitoring and interference hunting
- Fiber characterization and connector inspection at the tower and base station
- CPRI and fronthaul testing
- Site acceptance and closeout documentation
Why Choose It
The VIAVI OneAdvisor 800 replaces several separate instruments with one guided platform which cuts the tools a technician has to carry and standardizes testing across crews. Automated workflows and closeout reports reduce errors and rework and its modular design lets you add capabilities as networks evolve.
