Ja sam kupio sličan i poprilično sam zadovoljan.
Završiće ti posao u 90% slučajeva.
Neka te lepo služi!

P.S.
Obrati pažnju samo na njegovo ograničenje ulaznog napoa. Max 50VDC.

@tesla
Verovao ili ne - zalemljen je za te pare Smile 

@TDA
To mi je prvo zapalo za oko... 50vpk sa 1x sondom... Mislim da bi mi sonda 10x resila problem sa tih 50v tako da cu onda moci da merim mnogo vise ali ima vremena za to... prvo da resim problem sa ovim primekom jer ne radi kako treba...

Kada je niza freq onda je ok, ali kada idem na vise onda pocinje da se baguje donji deo signala... evo par slika... sada cu poslati u kinu da vidim sta imaju da kazu na tu temu... kao da operacioni pojacivac nema adekvatne uslove pa brljavi... ili tako nesto... pojma nemam...  po specifikaciji treba da radi do 200kHz ali meni je dovoljno i 50 samo da radi kako treba.... verovatno je bagovit primerak... videcemo...

Neki primerci dso138 sa starijom verzijom softvera, a ima ih dosta takvih u prodaji, imaju previse suma, koji se ovim jednostavnim zahvatom moze u prilicnoj meri smanjiti, Ja sam na dva primerka koji su bili kod mene uradio ovo i rezultat je itekako bio primetan...

Da li si siguran da je generator signala ok?

100% je ok... proverio sam sa drugim osciloskopom... a probao sam i sa racunarom da generisem signal i identicno se ponasa... pisao sam prodavcu i sad ocekujem odgovor...

Ovaj DSO deluje mnogoo bolji izbor, a cena nije previše paprena ...

On je nešto skuplji.
Ja sam uzeo ovaj i baš sam zadovoljan:

Poneću ga na skup da ga malo maltretiramo. Smile

Danas stigle STM32 Blue Pill plocice.

Da li postoji mogucnost da preko micro USB ubacim firmware u jednu blue pill tako da se ona kasnije ponasa kao Black Magic Probe (BMP).

U ovom uputstvu se koristi USB to Uart converter ja imam ovaj CP2102 sa slike on ima 3.3v napajanje ali neznam RX i TX koji su naponski nivoi da li smem da ih povezem sa STM board da ne ostetim MCU.

Možeš da vežeš Rx i Tx na taj UART to TTL (CP2102). Spoj još GND i 3.3V na Bluepill.

PA9 i PA10 su 5V tolerantni, tj skoro svi pinovi sa leve strane plocice su toleratni:

Nakon duzeg vremena gde sam se patio da prvo nadjem adekvatni enclosure pa onda da prilagodjavam rupe i oblik pcb-a njemu, stigao je ovaj mali printercic. Relativno mu je mala radna povrsina ali za moje potrebe dovoljna.

Kacim slike cim odradim prvi print.
