Merenja osciloskopom

Možda se nismo najbolje razumeli? Treba posebnom žicom spojiti masu skopa i masu DUT, a posle jedan (invertujući) vrh sonde na masu DUT, a drugi vrh (neinvertujuće ) sonde na mernu tačku.

Inače, na svakom osciloskopu postoji priključak za temeljnu masu skopa sa prednje strane, a upravo za te svrhe.

To je potpuno regularan (a i dobar) način merenja u bučnom okruženju.

Poput korišćenja simetričnog XLR ulaza za single end izvore, a za audio potrebe:

-jedan na masu SE izvora, jedan na vrući kraj SE izvora, a trećom žicom kutiju za kutiju, širm samo sa jedne strane spojen i nema frke sa ground-loop, ni sa kapacitativnim a ni induktivnim smetnjama ako su signalni vodovi parica.

Imati XLR ulaz kod audio aplikacija je prednost u svakom mogućem smislu, naravno ako je kvalitetno izveden.

Tipičan primer prednosti diferencijalnog pojačavača.
