The Fundamentals of Mixed Signal Testing
Course Information
The Fundamentals of Mixed Signal Testing course is designed to provide the foundation of knowledge that is required for testing modern mixed signal devices using ATE equipment. Many engineers are intimidated when confronting mixed signal test for the first time. However, the percentage of VLSI and SOC devices containing analog functions, data converters, DSPs, and similar circuits continues to grow. No longer a specialty or niche, mixed signal technology has entered the mainstream.

The Course
The course first introduces the instrumentation of a Mixed Signal Test System, with emphasis on the DSP (digital signal processing) capabilities. Ample time is spent explaining the mathematics necessary to fully understand signal sampling and waveform synthesis. Specifications for mixed signal devices are discussed and the method of verifying each individual parameter is explained in detail. The testing of Digital to Analog and Analog to Digital converters is covered step by step including device conditioning, analog filtering, grounding issues and noise effects. These details are fundamental to most all types of mixed signal circuits. Practical aspects of test development and debug are also discussed. To insure that each student gains a complete understanding of the concepts presented, virtual test instrumentation is used. Laptop computers play an essential role during the class to provide actual "hands on" lab experience. The labs demonstrate the principles of sampling, Fourier series, sinusoidal waveforms, FFT/DFT/Inverse Fourier transforms, signal generation and other mixed signal testing concepts. Each student receives a personal copy of the DSP Lab software, which can be kept for later use and a 300+ page reference manual titled "Fundamentals of Mixed Signal Testing".

Who Should Attend
Test and Product Engineers, Engineering Managers and Sales Engineers have all benefited from this course – it is the logical follow-on to Soft Test’s Digital Test Technology class. In addition, Design, Verification, and DFT Engineers find these courses to be a valuable resource for bettering their understanding of the IC test process.
