Oscilloscope Basics

Spectrum digitizer as an alternative to an oscilloscopeCan a digitizer be used as an oscilloscope? What is the difference between an oscilloscope and a digitizer? Should I better use a digitizer or an oscilloscope in my next application? These are interesting questions and the best way to start to answer these is the look up the dictionary definition of an oscilloscope: "An electronic instrument used to measure changing electric voltages. It displays the waveforms of electric oscillations on a screen."

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.

LeCroy oscilloscope WD2000Oscilloscopes have been invented in the 1920s. Up to now this instrument encountered many innovations.  In the beginning the most important manufacturers have been General Radio, DuMont, General Electric and Radio Corporation of America. Later Cossor and later Solartron dominated the market. Today the main players are Keysight, Tektronix and Teledyne LeCroy. Below we listed some important oscilloscope milestones.

tips for oscilloscope selectionThe oscilloscope is one of the most important tools used in the design, repair and maintenance of electronics. Nevertheless the selection of the right type and configuration for your application is not an easy task. We listed some important points to consider.

Tektronix oscilloscope with probesSignal measurement results can only be as accurate as the test and measurement tools in use.  As clock rates and edge speeds of today’s electronic circuits increase, probing becomes a critical piece of the measurement system – the component that comes in direct contact with your circuit.  This article looks at voltage probing considerations for embedded system and digital design debugging applications.
