Software customization to provide digital oscilloscope with enhanced period-measurement features

This paper tackles the problem of signal period measurements by means of oscilloscopes. First, the performance of two last-generation scopes, implementing a zero-crossing algorithm, is evaluated. Then, after a brief resume of alternative measurement techniques, a solution to enhance the period-measu...

Description
Summary:This paper tackles the problem of signal period measurements by means of oscilloscopes. First, the performance of two last-generation scopes, implementing a zero-crossing algorithm, is evaluated. Then, after a brief resume of alternative measurement techniques, a solution to enhance the period-measurement capability of scopes is proposed and implemented in the LeCroy WaveMaster 8620A software. Finally, the results of the tests carried out on different signal waveforms are reported and analyzed.
