# Spectra CX Radio Development Tool (Optional)

Spectra CX is a model-driven development tool that simplifies, accelerates, and validates a significant proportion of the SCA development

In addition, it validates SCA compliance at the architectural and unit test level.

• Generates SCA component source code in C & C++ that is correct by construction.
• Modeling, generation and deployment of SCA compliant waveform components on both GPP and DSP processors.
• Roadmap to FPGA modeling and VHDL code generation.
• Generates SCA compliant artifacts such as: XML descriptor files, compliance test reports and validation documentation.
Spectra CX enables SCA and non-SCA software aspects to be developed together, integrated early and thoroughly tested.
• Single integration model reduces development risk.
• Results in a faster time-to-market, lower costs, better software quality and superior compliance for all SCA waveform and platform code developed using Spectra.

# • SCA Radio Monitoring tool:

o Providing a uniform platform and waveform control mechanism.
o SCA based control of any waveform launched on the radio.
o Support for remotely installing and uninstalling waveforms in the radio.
o Support for switching between multiple waveforms without having to reboot the radio.
