JTAP OVERVIEW
The Aeronix JTRS Test Application (JTAP) is a software certification suite which exhaustively tests a Software Defined Radio for compliance with the international Software Communications Architecture (SCA) requirements. Sole developer of the JTRS Test Application (JTAP), Aeronix has been instrumental in testing numerous JTRS radios, as well as commercial SDR Core Frameworks, for compliance with the SCA specification.

USER INTERFACE AND CAPABILITIES
JTAP offers a familiar and easy-to-use Graphical User Interface, which is completely configurable by test or SCA requirement for the particular JTRS Operating Environment under test or development. A structured test tree is generated from XML, and is easily extensible for adding SCA Device or Resource tests, as well as any type of user tests. JTAP provides extensive test log capabilities with selectable log levels.

JTAP SYSTEM ARCHITECTURE
The following diagram presents a high-level overview of the JTAP software, as installed on a Windows 2000 workstation.

AERONIX JTRS SYSTEMS ENGINEERING SUPPORT EXPERTISE: BEYOND JTAP
Aeronix has supported the Department of Defense JTRS JPO with JTRS/SDR system engineering support since 1999. We have an experienced team of embedded hardware and software system designers that possess an intimate knowledge of the Software Communications Architecture and related Software Defined Radio technologies. Aeronix also supports other DoD and commercial vendors in SDR product development.

In addition to JTAP, Aeronix develops and supports several SDR "waveform" software applications, such as MIL-STD-188-220 /VMF and WiMAX 802.16.

Aeronix has developed and fielded software defined radios and waveform software for the US DoD for over 15 years. We are an active member of the Software Defined Radio Forum (SDRF), and the Object Management Group (OMG) SWRadio working group.

COMMERCIAL SCA TEST SUITE COMING SOON
Based upon the technologies developed for the Aeronix JTAP test tool, a "commercial" version of this test suite will soon be available internationally, and will be supported by Aeronix as a commercially-licensed product. The application will be available in current JTRS-compliant versions, but will also be enhanced to test against subsequent commercial and government versions of the SCA.

Aeronix is intimately involved in the evolution of SDR specifications, and plans to provide users with continued up-to-date test tools as these technologies mature. For timeframe, pricing, availability and purchase information, please contact us using the information under "Next Steps" at left.
