PROFESSIONAL EXPERIENCE

MOTOROLA (Austin, TX)                                                                                                      May 2000 – September 2002

Senior Test Engineer     

·         Developed and established performance standards for ADSL/VDSL set-top box (STB) systems in the areas of RF and baseband video/audio signal quality, digital picture quality, teletext and closed captioning transcode functionality, and Sarnoff MPEG-2 decoder compliance.

·         Designed, developed, and automated test regime to verify STB hardware, firmware, and software design to these established standards.  Researched and defined capital equipment requirements.  Wrote plans/procedures.  Executed tests.  Documented results and defects.  Provided support to design team in defect debugging.

·         Spearheaded significant improvements to video, audio, and ancillary data handling performance of STB systems as a result of defects found.

·         Acquired extensive knowledge and understanding of analog NTSC/PAL TV systems.  Tested and evaluated STB video outputs in formats such as composite, s-video, RF, component YprPb, and component RGB.  Extremely familiar with applicable baseband video test standards such as SMPTE 170M, ITU-R BT.470-6, EIA 250C, ITU-T J.61, SMPTE/EBU N10, and SMPTE/EBU N20.

·         Extremely proficient with analog video test equipment such as VM700T Video Measurement Set, 1765 Analog Waveform/Vector Monitor, TG2000 Multiformat Signal Generator, DS1000 RF Demodulators, and 8591C Cable TV Spectrum Analyzer.

·         Generated, analyzed, and recorded digital video/audio using MTS300 MPEG Test System, MPEG-2 Encoders, and DVB-ASI transport stream processors.  Utilized Audio Precision System Two Cascade for audio testing.

·         Characterized copy protected NTSC/PAL video signal from STB to obtain Macrovision certification.  Received certifications ahead of schedule in spite of having to overcome learning curve challenges.

·         Supervised, mentored, and coordinated Ethernet 10/100BaseT (physical layer) and RF Noise Figure test development projects for two electrical engineering summer interns.

·         Wrote scripts in Procomm Plus terminal emulation software to automate test processes.  Programmed VM700T functions to allow more efficient execution of repeated video test routines.

 

ECI TELECOM (Ft. Lauderdale, FL)                                                                                     August 1997 – January 1999

Compliance Engineer    

·         Evaluated and performed testing of network communications equipment to the regulatory requirements for safety, EMC/EMI/ESD, environmental, and telecom connectivity.

·         Utilized engineering laboratory equipment (oscilloscopes, spectrum analyzers, and multimeters) for electrical tests measuring RF emissions, DC power supply surge current, peak-to-peak noise voltage, system voltage during input power outage, and communication signal pulse masks and jitter.

·         Increased knowledge of various regulatory requirements (FCC Part 15, IEC 1000, UL 1950, CSA C22.2 950, EN 60950, FCC Part 68, CS-03, and Bellcore NEBS).
