a modern siglent shs800 handheld digital storage oscilloscope (dso) using lcd display


the first digital storage oscilloscope (dso) invented nicolet test instrument of madison, wisconsin. low speed adc (1 mhz, 12 bit) used vibration , medical analysis. first high speed dso (100 mhz, 8 bit) invented walter lecroy (who founded lecroy corporation, based in new york, usa) after producing high-speed digitizers research center cern in switzerland. lecroy (since 2012 teledyne lecroy) remains 1 of 3 largest manufacturers of oscilloscopes in world.


starting in 1980s, digital oscilloscopes became prevalent. digital storage oscilloscopes use fast analog-to-digital converter , memory chips record , show digital representation of waveform, yielding more flexibility triggering, analysis, , display possible classic analog oscilloscope. unlike analog predecessor, digital storage oscilloscope can show pre-trigger events, opening dimension recording of rare or intermittent events , troubleshooting of electronic glitches. of 2006 new oscilloscopes (aside education , few niche markets) digital.


digital scopes rely on effective use of installed memory , trigger functions: not enough memory , user miss events want examine; if scope has large memory not trigger desired, user have difficulty finding event.


dsos led creation of hand-held digital oscilloscopes (pictured), useful many test , field service applications. hand held oscilloscope digital sampling oscilloscope, using liquid crystal display display.


due recent rise in prevalence of pcs, pc-based oscilloscopes have been becoming more common. typically, signal captured on external hardware (which includes analog-to-digital converter , memory) , transmitted computer, processed , displayed.
