The Total System
The Thermo Scientific Lightning Test System (LTS) provides a modular test platform based on the lightning simulator
requirements of RTCA DO-160 Section 22, EUROCAE, Boeing, Airbus and others. Based on the proven modular
construction of the Thermo Scientific ECAT System, the LTS can be upgraded in the field by the user or in the factory as
requirements change by the addition or replacement of individual modules.
The LTS can perform Pin Injection, Cable Bundle and Ground Injection testing with Single Stroke, Multiple Stroke and
Multiple Burst modes from the same module. The system can be expanded as test requirements evolve. Purchase of
additional frames allows the operator to double his capacity using existing modules, without purchasing another system.
Turn-key Testing
With the advent of the Thermo Scientific LTS, lightning testing of avionics comes of age and provides an easy to use, turn-
key solution for test engineers and technicians.
Until recently, the availability of commercial equipment for testing to lightning standards for avionics, such as RTCA DO-
160, has been limited. Most test equipment used in the industry was home made: difficult and time consuming to set-up
and awkward to use, requiring skilled engineers for their operation and maintenance.
Testing with the LTS insures repeatable, reproducible test results while virtually eliminating tester set-up time. Waveforms
and functions are selected with the push of a button rather than by reconfiguring test equipment and wiring. The LTS can
significantly reduce total test time resulting in significant cost savings.
Versatile, Modular Architecture
LTS waveform simulators are completely modular, using plug-in modules that provide all the waveforms required to meet
the lightning test requirements of RTCA DO-160, EUROCAE, Boeing, Airbus and others.
Any Thermo Scientific LTS simulator can be readily expanded, at any time, for testing to new or modified standards. These
modules can be added or replaced by the operator, without requiring a field service engineer, or shipping to the factory.
Rather than purchasing or constructing a new tester, replacement or addition of plug-in modules saves time and money.
Upgrades are considerably less expensive than individual instruments, and what’s more, LTS modular systems are totally
open-ended and will be able to handle future requirements, whatever they may be.
Thermo Scientifics’ plug-in architecture protects you when standards are changed or superseded as the industry
understanding of lightning threats to aircraft avionics evolves, and as industry standards evolve.
