Sonda osciloscop

Recommended Posts

Buna seara!As vrea sa-mi confectionez o sonda pentru osciloscop si va cer ajutorul in a o confectiona,osciloscopul are impedanta de intrare 1Mohm/36pf. Initial am facut un divizor de tensiune 1Mohm per 100Kohm dar nu l-am compensat si imi indica prostii,frecventa maxima n-o sa depaseasca 200-300khz,va multumesc!

Ma gandeam sa folosesc cablu coaxial din ala pentru antena mai vechi,stiu ca nu e cea mai potrivita solutie dar deocamdata e de ajuns.
