Datasheet

Overview

The VIAVI Trilithic 360 DSP D3.0 Pro (part number TRI-DSP-360-D30-PRO) is the DOCSIS 3.0 Pro version of the 360 DSP signal level meter in the DSP Series. It is built for installation RF signal testing and troubleshooting by cable installers, contractors and service technicians, and covers analog and digital signal measurements, channel plan scans with tilt, return spectrum from 4 to 205 MHz and forward spectrum from 5 to 1250 MHz.

The meter has a color touchscreen interface, simple pass/fail indicators and autotest apps for standardized installation procedures. It also has a quick charge time, a built-in LED flashlight and a glow-in-the-dark keypad for work in dark, cramped spaces.

Communications and StrataSync

The 360 DSP has a built-in cable modem plus Ethernet and Wi-Fi. On the D3.0 model the internal modem works in DOCSIS 3.0 (32x8) mode, and the meter uses it for cable modem statistics, network connectivity tests and throughput tests. Test results can be synced to StrataSync over Ethernet, DOCSIS or Wi-Fi. This gives near real-time views of measurement data, lets work orders be handled through the StrataSync workflow and keeps inventory and firmware records for each instrument.

Advanced and Pro functions

Like the Advanced models, this one includes a Frequency Domain Reflectometer for finding the distance to cable faults and a source generator for the 5 to 85 MHz return band. The Pro level adds three functions. Upstream Traffic Control Plus gives a real-time heat-map view of upstream ingress. Upstream linear distortion measurements cover equalizer taps, group delay and in-channel response. QAM Error Vector Spectrum analysis shows ingress underneath downstream channels.
