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.

FCC Part 15 Compliance

Note: This equipment has been tested and found to comply with the limits

for a Class B digital device, pursuant to Part 15 of the FCC Rules. These

limits are designed to provide reasonable protection against harmful

interference in a residential installation. This equipment generates, uses,

and can radiate radio frequency energy and, if not installed and used in

accordance with the instructions, may cause harmful interference to radio

communications. However, there is no guarantee that interference will not

occur in a particular installation.

Pursuant to FCC 15.21 of the FCC rules, changes not expressly approved by Trilithic, Inc.

might cause harmful interference and void the FCC authorization to operate this product.

The internal antenna used for this instrument is installed at the Trilithic factory or by Trilithic

approved repair facilities. During operation of the device, a distance of 20 cm or more should

be maintained between the antenna in this device and any persons and must not be co-located

or operating in conjunction with any other antenna or transmitter. To ensure compliance, do not

operate at closer distances than this. The antenna on the 720 DSP is located inside the device

at the top of the unit attached to the back plastic case. Do not use any antenna other than the

installed antenna.

If this equipment does cause harmful interference to radio or television reception, which can

be determined by turning the equipment off and on, the user is encouraged to try to correct the

interference by one or more of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the device and receiver

• Connect the device into an output on a circuit different from that to which the receiver is

connected

• Consult the dealer or an experienced radio/TV technician for help
