Debugging of DSP Measurements

Abstract:

Using DSP techniques for making automatic measurements often presents unique challenges. Most of the time, they provide fast accurate measurement of AC signals. At times, these techniques will generate erroneous results. While the results may not be what is expected, the numerical results often give no clue to what need to be corrected.

This paper will explore the vulnerabilities of DSP measurements. It will also present techniques for determining what effects are responsible for different types of problems encountered in sinewave measurements.

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.

Frequency Ratios for DSP Measurements

Abstract:

DSP waveform instruments offer higher test performance through coherent measurements based on using precise frequency ratios which are obtained by solving a set of integer constraints. This paper presents analysis tools used to solve these constraints.
