1. Abstract Previous senior design teams developed an amplifier board for Teradyne Corporation. This board will boost the input signal to a computer-based spectrum analyzer also designed by a previous senior design team. The assembly of the amplifier needs to be finished, and the board must be successfully powered up and debugged. Teradyne needs this board to be thoroughly tested to ensure it will meet specifications. Solutions should be proposed for any errors discovered during testing, and as time allows, these solutions should be implemented and the board re-tested. Introduction Design Objectives Tests will verify all specifications Results will be well-documented Tests will be repeatable Functional Requirements Support signals from 0Hz - 100MHz Amplification gain of up to 60dB Under 1mV DC-offset after calibration Low noise and distortion Project Milestones Assembled and functional prototype Completed test plans Completed testing and test reports Documentation of proposed solutions Proposed Approach Debug board design Research technologies used Assemble prototype Develop test plans Simulate circuit for debugging Automate testing Product integration Support Technologies LabVIEW PSpice Altera Quartus II PCB Express Time domain testing Frequency domain testing Financial Requirement Description Cost FPGA$ 60 Components$ 13.2 Poster$ 30 Total Cost$103.2 Team Members Jesse Bartley Zhi Gao Michael Hayen JiWon Lee Client Teradyne Inc.

Rigorous testing and will ensure that the amplifier board can provide this input signal with sufficient gain and bandwidth, and minimal distortion and noise. The tests will result in a list of improvements and corrections that can be made to the board in order to meet or improve the performance specifications.
