SCA Devices and Services

A primary objective of the Software Communications Architecture (SCA) is to enhance waveform application portability across different hardware platforms executing different Operating Environments (OEs). The aim is to write business logic that can be easily ported from one platform to another.

A key element for SCA Waveform portability relies on Hardware Abstraction.


Hardware Abstraction

The SCA achieves Hardware Abstraction by utilizing publicly available open APIs for different hardware elements.
