Mixed Signal Fundamentals Overview

sinxfreq d2afilt

“The Fundamentals of Mixed Signal Testing” explains the concepts and methodologies of testing mixed signal devices using ATE equipment. The instrumentation of a Mixed Signal Test System are introduced, with emphasis on the DSP (digital signal processing) capabilities. The mathematics necessary to fully understand signal sampling and waveform synthesis is clearly explained. 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. Many practical aspects of test program development and debug are also included.

Virtual Test Instrumentation is used to insure a complete understanding of the concepts presented. Each manual contains one copy of the Soft Test DSP Lab simulation software for Microsoft Windows. The DSP Lab software provides actual “Hands On” leaning and demonstrates the principles of sampling, Fourier series, sinusoidal waveforms, FFT/DFT/Inverse Fourier transforms, signal generation and other mixed signal testing concepts.
