A Comparison between Oscilloscopes and Spectrum Analyzers

oscilloscope spectrum analyzer functionWhether it is for a land survey searching for minerals on Earth, or for a space exploration in search of alien life forms, the analysis of any signal boils down to looking at its time and frequency information. While an oscilloscope displays a signal with respect to time, a spectrum analyzer shows it with respect to frequency. Both of these tools are very important in any signal analysis application. This article explains the difference between oscilloscope and spectrum analyzer using examples.

Precision Phase Noise Measurement with an Oscilloscope - Part 1

AA PhaseNoise CaptionOften clock jitter induced from the power supply noise, signal routings, or other signals severely degrade the performance of the system. Clock generation and distribution in a FPGA for a high speed analog application is particularly prone to these issues. They manifest themselves in phase noise or clock jitter, which is the random variation of the period of a signal over time. Clearly, optimization of the design requires verification of the integrity of such clocks.
