Sziasztok!
Szeretném megérdezni, hogy használ-e Valaki VOLTCRAFT DSO2100 oszciloszkópot?
(PC párhuzamos portjára csatlakozó, 30MHz szkóp)
Köszönettel:
AG.
Üdv mindenkinek!
Vettem egyik kollégától egy, a fennti cimben megadott tipusú, pc oszcilloszkópot.
A készülék müködik, miután nagy nehezen sikerült feltelepitenem win xp alá (eredtileg win95-ösre készült).
Ám van vele egy kis gond: az ábrázolt jel nem stabil, van egy lassú vizszintes remegése. A belső tápban a kondikat ellenőriztem és jók (ESR).
Valahogyan az az érzésem, hogy ez nem programhiba, hanem a szkóp, szinkron áramkörének hibája, mert ha igy lenne, akkor nincs más mód, igy fogom használni, mert a javitás szóba sem jöhet kapcs. rajz nélkül, ugyanis ilyesmit nem találtam a neten.
Ha valakinek lenne véleménye vagy tapasztalata e témában, kérem segitsen.
Elöre is köszi.
Becze Zsolt.
Hello to everybody,
I have bought a defective Gould oscilloscope DSO420. At the beginning of the repair the power fuse was blown immediately after inserting the power plug: The RF-filter connector was shorted. Okay, ignore the RF-filter for now.
Some leaked capacitors were within the power supply, all renewed as well as the NiMh accumulator.
Now most of the scope is running:: All LED at the front as well they are switchable and the screen of the scope was lightened th but only a vertical line is shown. No horizontal deflection at all.
The circuit I have attached, all semiconductor are renewed, no change. The electrolytics are renewed, no change. Allways a vertical stroke. Does anyone have an idea?
Regards from Hamburg
Jens

Sziasztok!
Úgy gondoltam nyitok egy ilyen témát, mert én teljesen el vagyok már benne veszve, se egy jó youtube videó, se egy jó leírás nem akadt eddig a kezembe a fent említett készülékkel kapcsolatban.
Legelőször is egy-két alap dolog:
-1GB-os FAT-ra formázott SD kártyát beletettem, de nem tudok rá menteni. Mit kell vele csinálni, hogy elfogadja?
Amikor save BMP-t választom, kiírja, hogy "Disk busy".
-Firmwire frissítés.
Honnan töltsem le, hogyan tegyem rá, mi a pontos menete?
Ha olyan írná le aki már csinálta, sokkal magabiztosabban merném én is csinálni, mert nem szeretném kinyírni 2nap után az egészet.
Ehhez hasonló okosságokat várok ide leginkább, de bármi tipp, trükk, jótanács jöhet.
