These slides focus on the latest addition to PrismTech’s Spectra DTP family of advanced Software Communications Architecture (SCA) compliant and Radio Frequency (FR) capable Software Defined Radio (SDR) and test platforms. Spectra DTP4700 is based on the latest digital processing subsystem from Mistral and contains a high performance Texas Instruments AM/DM37x Sitara processor with GPP and DSP functionality on the same chip. When combined with DataSoft’s Monsoon Transceiver, DTP4700 provides a fully-fieldable radio with a base level of RF performance between 400 MHz and 4 GHz. For ease of development DTP4700 provides an integrated SCA Operating Environment containing an optimised Linux operating system, SCA Core Framework (CF), CORBA middleware, SCA platform and SCA sample waveform. Spectra DTP4700 is fully supported by PrismTech’s market leading Spectra CX tool for SCA waveform modeling, code generation and compliance validation. Spectra DTP4700 is an affordable, yet functionally advanced desktop system targeted at waveform and application development/test teams in major radio OEMs and their end customers, advanced wireless communications (government and defense) laboratories conducting research in fields such as cognitive radio, electronic warfare, and secure SDR waveforms, internal research and development (IR&D) projects and independent SCA developers creating software IP for the SDR market.
