But how about the time you solved the problem? Suppose a sudden power failure happened and the monitor port of your custom board couldn't give any output. Could you find the problem in no time like 5 - 10 minutes at most? I met this problem twice on my custom board. It took me one night to find out the problem at first under help of BDI2000 and Oscilliscope without any experience. The problem was SDRAM damage. And BDI2000 helped me make sure that 4 SDRAM chips on board were all broken. Second time, I just found out the real problem in 10 minutes or so with BDI2000. There were 2 broken of 4 parallel FLASH chips in 8-bit. So, IMHO, for the sake of efficiency and accurateness, BDI2000 is much better than Oscilliscope, at least in time critical situation like trouble shooting. ===== Best regards, Sam _________________________________________________________ Do You Yahoo!? 150??MP3???????????? http://music.yisou.com/ ??????????????????? http://image.yisou.com 1G??1000??????????? http://cn.rd.yahoo.com/mail_cn/tag/1g/*http://cn.mail.yahoo.com/event/mail_1g/
