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
