# 2.7: SDR Band Output Validation Device

3. Project Overview
Software-defined radio (SDR) systems substitute digital functions for many traditionally analog functions
These systems periodically receive software or firmware updates
As new software is added to the SDR, existing functions must be validated to confirm they still function correctly
End Goal: Validate the external band data function on all SDRs in the Flex-6000 Signature Series line.
State the problem and the project in clear terms. Use a graphic if at all possible.

4. Project Motivation The Problem: The Solution:
Currently there is no automated method to verify the software that produces the USB band-data continuous to function properly
The Solution:
Create a device that automatically catches an issue in the software right when it is coded

15. Future Work
The SDR Band Output Validation Device met all of FlexRadio’s requirements
In the future, the device could be enhanced so that it is enabled to receive serial commands from the radio if desired by FlexRadio
BRIEFLY give 2-4 bullets of future work. BRIEF
