Nu as da nici mort 17 mil pe un osciloscop digital care imi afiseaza pe un ecran 320x240.

 

In locul tau as cauta un osciloscop analogic, cu tub catodic, second hand, la pret de maxim cateva mil.

 

Daca totusi insisti sa fie digital (mie nu-mi place digital, are multe dezavantaje fata de cel analogic) ia-ti unul USB de maxim 100 euro acolo si face acelasi lucru ca si cel de 500 euro.

Problema este ca nu prea exista osciloscop pc-based la 100 euro care sa fie cit decit bun (nu o sa imi cumpar unul la 10 MHz) , unul analog ar fii bun pentru ca se vizualizeaza cel mai bine semnalul insa daca vreau sa fac masurari mai pretentioase o sa fie jale ...
