They're perfectly fine scopes if you don't need triggered sweep[1]. Some of them even play games. [1] even those old Telequipment units would trigger on *some* waveforms. -- If John McCain gets the 2008 Republican Presidential nomination, my vote for President will be a write-in for Jiang Zemin.

Once again, you show a great lack of understanding. I have several glass 1N4004 diodes in front of me. -- Service to my country? Been there, Done that, and I've got my DD214 to prove it.

Sigh, I only have datasheets from 20, stored in my computer. But, I have them from Won-Top, Leshan Radio, Gulf Semi, Formosa Micro, Dachang, and Bytesonic, to name a few they don't have, SFAICS. Plus, I have multiple versions from several of the companies. So there! So many files, so little time. -- Thanks, - Win

They are as big as the plastic versions. -- Service to my country? Been there, Done that, and I've got my DD214 to prove it. Member of DAV #85. Michael A. Terrell Central Florida |
