Tiszteletem! Az alább linkelt topikban már volt szó erről a szkópról: http://elektrotanya.com/?q=hu/content/hc-dso2100-pc-oszcilloszkop-jel-vizszintesen-remeg-megoldva Ott felmerült, hogy ki lehetne váltani a belső +/-5V-os tápot a melegedés miatt külső egységre. Hát megpróbáltam... Ezt találtam: MEAN WELL DKE15A-05 http://www.tme.eu/hu/details/dke15a-05/dcdc-konverterek/mean-well/ Ez az átalakító +/-5V-ot állít elő áganként 1,5A-es terhelhetőséggel. Átalakítottam, mégpedig úgy, hogy átvágtam a stabil kockák kimeneti lábait, és bekötöttem a DC-DC konverter kimeneteit (a két +5V-os ág párhuzamosítva). Jelentem működik! :taps2: Viszont durván zajos lett a szkóp jelképe. :redsad: Feltételezem, a DC-DC konverter működéséből adódóan zajos a kimenete. A beállításoktól függetlenül egy kb. 180kHz-es zajsáv az egyenes vonal. Tanácsot kérek, hogyan lehetne kisimítani a tápot. Azt azért tudom, hogy ezt jó nagy puffer kondival nem fogom kisimítani. Igazából az a kérdés: van-e valamilyen univerzálisan használható L-C áramkör, vagy kreálni kéne valamilyen sávszűrőt hozzá? Ha működhet univerzális megoldás, akkor szívesen fogadnék kapcsolásokat, értékeket. Köszönettel: Gábor
