Team Members & Roles NAME ROLE Zachary Gonzalez, Project Manager Sponsor Liaison, Component Selection, Software Design Yusuf Agoro, Engineer Circuit Design, PCB Assembly, Software Coding Jonathan Tavira, Engineer Circuit Design, PCB Layout, System Test # 2.7: SDR Band Output Validation Device

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. # 2.7: SDR Band Output Validation Device

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 Why are you doing this project? What’s important / needed / beneficial about it? Why is this a good senior design project? MAKE FONT BIG # 2.7: SDR Band Output Validation Device
