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.

Digital Debugging - better using a Mixed-Signal-Oscilloscope or a Logic Analyzer?

Tektronix mixed-signal oscilloscope MSOToday’s technology is fundamentally balanced on an increasingly fine line between the analogue and digital domains; as data speeds increase — both within and between devices — the ‘ideal world’ of fast, clean digital transitions becomes evermore difficult to achieve. This presents new and escalating challenges when verifying faster digital signals that exhibit more and more analogue-like features. As a result it is becoming necessary to remove the hard line between digital and analogue.
