Datasheet

Overview

The VIAVI Trilithic 360 DSP is a signal level meter in the DSP Series, designed for fast installation RF signal testing and troubleshooting by cable installers, contractors and service technicians. It provides the analog and digital signal measurements needed to verify an installation, including DOCSIS 3.1 OFDM signal analysis.

The meter has a color touchscreen interface, simple pass/fail indicators and autotest apps for standardized basic RF installation, triple-play tests and home certification. A built-in LED flashlight, glow in the dark keypad and quick charge time support work in dark, cramped spaces.

Communications and StrataSync

The 360 DSP has a built-in DOCSIS 3.1 cable modem, Ethernet and WiFi communications. The internal modem supports network connectivity and performance testing, upstream and downstream cable modem statistics and OFDM profile analysis. Test results can be uploaded to StrataSync for near real-time views of measurement data, and the StrataSync workflow option allows work orders, test profiles and pass/fail thresholds to be sent to the meter.

Model versions

The 360 DSP is offered in DOCSIS 3.1 and DOCSIS 3.0 versions. Advanced models add a Frequency Domain Reflectometer and Source Generator; Pro models also add Upstream Traffic Control Plus, Upstream Linear Distortion measurements and QAM Error Vector Spectrum analysis.
