DSP Measurement of Under-Settled Signals

Abstract:

This paper explores the effects of settling transients on DSP sinewave measurements and techniques that allow measurements to begin before settling is complete. It shows the effects of many settling transients can be virtually eliminated.

Testing High Speed, High Accuracy Analog to Digital Converters in ADC Embeeded in System-On-Chip

Abstract:

High speed, high accuracy ADC’s built on SOC IC’s tested on digital testers with round-trip-delays, must measure INL, DNL, Gain and Offset. Algorithm efficiencies and round-trip-delay sensitivity are analysed. Efficient test methods are described.

Specmanship

Abstract:

Specmanship is the art of improving the appearance of technical specifications which, once improved, may no longer reflect reality. For example:

RF Specifications:

Bandwidth is often stated without supplying critical information such as pitch, ground configuration, and dielectric, and is of course reported under ideal conditions.

Improving Power Delivery in the Test Interface

Abstract:

Power integrity is the discipline of providing clean power to the DUT by minimizing noise on the Power Delivery Network (PDN). It is quickly becoming one of the biggest challenges in test interface design. By maintaining a low impedance path from tester to DUT across all operating frequencies of the device, a constant voltage can be provided to the DUT in high di/dt environment.

Frequency Stability and Frequency Stability Parameters

Introduction:

Digital engineers look at frequency stability in the time domain. This is because digital signals are, in most cases, viewed in this domain as pictures on an oscilloscope. Similarly, timing jitter, which is an interpretation of frequency stability, is also viewed on an oscilloscope as “blurred” signal edges.
