1. iLab Final Presentation EE 496 May 4, 2007

2. Members Ka Hing Chan – Male – Age 21 Nana Kim – Female – Age 22 Chong Quach – Female – Age 40

3. Overview of Project Objective: to design an affordable and space efficient all-in-one laboratory device. Device will include: – Power Supply – Function Generator – Oscilloscope – Spectrum Analyzer – DMM

4. Initial Goals Build Generator portion – Provide adjustable DC power ranging from -20V to +20V – Generate sine, square, triangle waves w/ adjustable frequency and amplitude (10 Vpp max) Push buttons to adjust features to test accuracy and precision

5. Overall Design

6. Decisions Made Number of outputs – 5 DC outputs (2 fixed pos and neg ports, 1 GND) – 2 Analog wave outputs Direct Digital Synthesizer (AD9833) vs. PSoC Transformer vs. DC-DC converter Buy C Compiler vs. Free Assembly Code

7. Structure (Generator) USB SPI Analog Waveform DC PSoC (CY8C29xxx) DDS (AD9833) Positive Negative USB Host/Client MAX3421E DDS (AD9833)

8. Design Tools PSoC DesignerPCB Express

9. Current Status Received all chips Completed circuit design Setup SPI in PSoC Designer

10. Problems Time!!!!! Limited Resources PSoC Assembly Language Lack of $$$$ – C Compiler = empty wallet – PCB Boards = arm + leg – Error in PCB Boards = Incomplete Grade

11. To Do List Re-order PCB boards Test Chips Design command procedure and language

12. Future Improvements More time in development stage – Explore options before committing Better time management – Follow and commit to timeline Use Design Notebook – Makes writing paper easier

13. Have a Great Summer!!!! Questions?
