Za potrebe servisejev isščem ročni osciloskop.
Same zahteve so zelo minimalne, predvsem pa je ključna robustnost.

Osciloskop naj ima sledeče karakteristike:

1 kanal (ok, mogoče dva kanala)
do 1 Msample/s
Ročna varianta

Potrebovali bi ga za analizo signalov na 485, rs232 vodilu (hitrosto do 110 kbs)
potem pa za analizo zvoka nekej do 30 khz

nekaj razmišljam o POSCOPE, ki pa je malo preštorast za na kakšno lestev.

Kaj predlagate?

To meni izgleda kot en MP4 predvajalnik / recorder predelan v DSO
Vprašanje, kako je narejen analogni vhod...

Tudi tukaj je (bil) eden:

Zanima me, če kdo uporablja te ročne osciloskope in kako se obnesejo?

Lep pozdrav.

V tem dokumentu je nekje na koncu celotna shema. (=

JYE Tech naj bi naredili novo verzijo naprej od DSO 062 DIY kit http://www.jyetech.com/Products/LcdScope/e062KC.php , DSO 082 http://www.jyetech.com/Products/LcdScope/e082.php .
Zanima me, katerega priporočate za elektronika začetnika, s katerim bi iskal napake-nedelujoče elemente v preprostih vezjih? Ali raje tega: DSO nano http://www.seeedstudio.com/depot/micro-digital-storage-oscilloscopedso-nano-p-512.html ?
