Trilithic DSP Series Meters
Value-based models for every technician work group
The DSP Series Meters
As cable networks migrate to newer technologies, and
anticipating an eventual move to DOCSIS 3.1 and 1.2
GHz downstream range for all meters, the complete
VIAVI meter line provides these installation and service
measurement capabilities for cable service providers
and contractors. These robust and compact DOCSIS 3.1
meters are known for their long battery life.
The 180 DSP-Lite starts the line with basic measurement
capabilities, including levels, and DOCSIS 3.1 OFDM
signal quality.

VIAVI Trilithic DSP Series Meters
Basic Signal Level Meter – 180 DSP
A dependable tool for basic cable installation needs, the 180 DSP signal level meter features a compact rugged
design, easy-to-use color user interface and an unparalleled selection of digital and analog channel measurements,
including DOCSIS 3.1 OFDM signal analysis.
When testing or troubleshooting within analog, digital or mixed analog/digital transmission systems, the 180 DSP
is the perfect tool for measuring analog and QAM carrier power levels. Additionally, for QAM carriers (including
deep interleave) the 180 DSP provides Hum
1
, Constellation, Equalizer Tap, MER and BER measurement displays.
This allows users to quickly analyze 64 and 256 QAM downstream channels for quality verifications or to locate
impairments with the meter, all right out of the box.
The 180 DSP performs an extensive set of OFDM signal measurements to enable testing in DOCSIS 3.1 deployments.
In addition to average level, peak-to-valley, and in-channel tilt, the meter displays PLC constellation, level, pre/post
BER, MER, decoder stress over time, and a summary for the default profile.
With its channel plan scan feature, the 180 DSP displays the frequency response of the entire channel lineup. This
measurement displays a color-coded bar graph of each channel or your favorite channels in the active channel plan.
The channel plan scan also includes on-screen markers that can be adjusted to perform a tilt measurement.
The 180 DSP comes standard with the ability to display the full return spectrum from 4 to 205 MHz. The spectrum
display provides peak measurements, color-coded markers, and delta measurements. This feature also includes
adjustable detector modes which are useful for capturing bursty transient noise. The 180 DSP optionally performs
forward spectrum measurements from 5 MHz to 1,250 MHz

Installation Troubleshooting and Certification – 180 and 360 DSP
180 and 360 DSP signal level meters are specifically tailored for fast installation RF signal testing and
troubleshooting. These meters come equipped with all needed analog and digital signal measurements to ensure
the highest quality installation—and at a price point that makes it feasible for system operators to outfit their
entire fleet.
Designed for installer, contractor and service tech challenges, the 180 and 360 DSP help simplify decision making
and streamline standardization processes and procedures, while improving tech efficiencies and the overall health
of the entire system.
The 180 and 360 DSP feature intuitive, color touchscreen interfaces, simple pass/fail indicators, and autotest apps
to streamline basic RF installation and make the installer’s job easier. These meters are built with the technician
in mind—from the quick charge time to the unique, built-in LED flashlight and glow in the dark keypad for those
dark, cramped spaces.
The 180 and 360 DSP meters make basic RF installation a breeze for installers and contractors. Techs will appreciate
the advantages of a quick and efficient device, featuring a flexible and easy-to-operate interface inspired by
modern smart devices. These next-gen fulfillment tools come equipped with powerful troubleshooting tools and
simplified autotest apps to perform triple-play tests, set home certifications standards, and measure both Analog
and Digital signals. The 360 DSP has built-in DOCSIS 3.1 Modem, Ethernet, and WiFi communications capabilities,
and test results can be easily to StrataSync for near real-time views of measurement data.
