Putting Innovation Within Reach
Product innovation at Trilithic has always been characterized by one thing: it’s practical. It
makes life easier for customers. It’s the natural result of listening to them. That philosophy
has been the driving force behind the company’s growth from its beginnings as a two-man
engineering team in 1986 to its current position as a global manufacturer with more than 130
employees.
A privately held company, Trilithic broadend its original RF and microwave component product
line by acquiring Filters manufacturer Cir-Q-Tel and instruments manufacturer Texscan, adding
broadband solutions to the product line. The company also expanded operations to Thailand in
2001, to meet increasing demand for its products in the growing markets of Asia.
As new communications applications continue to emerge, part of Trilithic’s business has
evolved into managing change—helping customers respond quickly to market opportunities
with innovative technology and individualized solutions. But the core value of Trilithic’s
business approach—listening to customers—hasn’t changed. Keeping that focus intact will
help provide better products in the long run and ensure continued growth for decades to come.
Trilithic is comprised of two major divisions:
Broadband Instruments
The company is best known for innovations in signal level measurement, leakage detection
and reverse path maintenance—like the use of Digital Signal Processing (DSP) technology,
which lets eld technicians upgrade their signal analyzers by simply downloading rmware.
Emergency Alert Systems
Trilithic’s EAS division is a leading supplier of homeland security government-mandated
emergency alert systems for broadband and other communication system providers. As
the communications industry continues its rapid evolution, Trilithic has begun offering
comprehensive systems and services to address a wide variety of emergency alert system
needs, including the design and architectural layout of complex analog and digital EAS
networks.

Introduction
The Standardization Solution
Trilithic’s 720 DSP™ conveniently combines CATV and Gigabit Ethernet testing in a single
meter for troubleshooting and installation of both residential and business services.
Multi-service verication can now be achieved with one instrument containing everything
needed for service, business, or residential installations. Eliminate the need for multiple
instruments in most business services with Gigabit Ethernet Throughput testing and save
capital expenditures at the same time.
Tailored for the challenges faced by installers, contractors and service techs, this meter
comes equipped with all of the powerful troubleshooting tools for the experienced tech, yet
helps simplify decision making and streamline standard processes and procedures for the
more novice tech. This improves tech efciencies, the overall health of the entire system,
and allows techs to grow with the meter.

verify service quality and easily identify and x problems in the eld.
• Multi-user support
• Multi-language support
• Create work orders right on the meter
• Built-in web browser, real-time data transmission
• Interactive autotesting apps
Autotest Apps
The 720 DSP features next generation autotest applications that practically walk the
technician through a job. By performing standardized measurement tests at various
required locations on the job site using custom test plans, channel plans and limit sets,
the meter very clearly indicates (using color and symbols) what areas still need attention,
before the technician leaves the job site.
Multi-user support allows technicians that work in various territories to easily switch channel
plans and standardized autotest apps and test limits or login as a completely different
user. The built-in web browser allows techs to upload job data in near real-time as well as
transmit and receive channel plans, autotests, work orders and rmware.
Leaving less room for entry error, this new simple user interface can translate into less
training and more efcient time in the eld for techs. Although the 720 DSP comes
equipped with all of the required troubleshooting tools for an advanced maintenance
technician, it also offers a higher comfort factor for novice technicians, reducing decision
making in the eld, which can ultimately result in more productive work days and more
satised customers.

Justify ROI
Field operations managers can now easily verify that all of their technicians are performing
the proper tests and are doing so at the right place and time—in near-real time. The
potential benets include identifying techs who need additional training, improving team
performance, reducing truck rolls and cutting operating costs could obviously be signicant.
At a higher level ViewPoint can deliver simple, standardized, system-wide reports and
dashboards that can help a director or VP of technical operations view the entire operation
at a glance to gain information that can be used to reduce service and repeat trouble calls.
Essentially, this integrated system approach allows cable operators to see much more
of their plant-wide operations and use the information in practical ways. The insights can
enable them to identify both localized problems and high-level system issues to make
decisions based on a clearer understanding of their overall operations and the associated
ROI.
Combining 720 DSPs in the eld with the new ViewPoint WFM Module in the back ofce,
managers can view the health of their entire system—in near real-time, for total installation
& service management.
Total System Management
Combining the 720 DSP meter in the eld with
the new ViewPoint Integrated Server in the back
ofce, managers now have simplied access
to intelligent management tools for monitoring,
assessing and improving the efciency of their
total operation while making it even easier to
obtain consistent, repeatable results that give
supervisors that birds-eye view of the eld for
Total System Management.
By unifying an entire MSO’s eld operations in one convenient dashboard, managers can
easily verify compliance and quality throughout the entire plant, either by home, system,
region, division or any other attribute from a billing system.
This simple and completely customizable integrated system of eld analysis and reporting
tools allows managers to watch over their entire eld operations in one convenient
dashboard that compares each location in the system, analyzes the overall health of their
entire organization and addresses concerns in near real-time.

Cleaning the Display Screen
The touchscreen LCD display of the 720 DSP requires special care when cleaning. This
display is sensitive and can be easily scratched or damaged while cleaning. To clean the
display screen of the 720 DSP, use an ultrasoft, clean, lint free, microber cloth.
To clean ngerprints and greasy smudges off the display screen, use a bottle of screen
cleaning solution designed for LCD displays. Put a small amount of screen cleaning solution
on a cleaning cloth and then wipe the screen gently.
For correct cleaning of the display, follow these four simple steps:
1. Turn off the 720 DSP before you begin. If the screen is dark, it will be easier to see any
areas that aren’t clean.
2. Very gently, wipe the display with an ultrasoft, clean, lint free, dry cloth. If this does not
completely clean the display, DO NOT press harder on the screen in an attempt to clean
the screen as this may cause permanent damage.
3. If Step 2 does not work, spray screen cleaning solution onto the cloth. Never spray the
screen cleaning solution directly onto the display screen.
4. Let the screen dry completely before turning on the 720 DSP.
Damage caused by improper cleaning of the display screen
will void the warranty of the 720 DSP.
