Digitalni osciloskop

[Soltisik Miroslav]

>> ved od osciloskopu nic ine neocakavam. 
No ale osciloskop je pristroj na meranie v casovej oblasti. Ak nemozem
vdaka osc. merat casove veci na signale neperiodickom, potom pouzivam
nespravny merak na nespravne meranie. Ale iny nemame.

>ale zakladne pravidlo je neverit slepo tomu co ukazuje pristroj a
rozmyslat.
Vytesat do kamena alebo vyleptat do zlatej platnicky.

>Sice sa to vyrazne vylepsilo s prichodom novych digitalnych modelov od
renomovanmych vyrobcov
Bohuzial, kamenom urazu je vstupna analogova cast a filter. Za nimi je
uz len snaha vyrobcov o co "najpresnejsie" (citaj najkrajsie,
najGUI,...) vypocty.
Ale ak mam na vstupe (za analogovou castou) zmrseny signal, uz to
nedobehnem ziadnymi matematickymi operaciami.
Bohuzial potom nastupuje marketingova masaz, PR a uvedena psychologia
"za tie prachy to musi byt ok".
Nie je.
