Hello, Unmounted acquisition board Not much time to find the culprit. Capacitor removed and board cleaned, no more short circuit. I will replace it and make the change for acquisition at 2GB/s. I think it is necessary to put a resistance 0 ohm on r154 I think. Under reservation that nothing else burn.... cdt |

See this link to pass at 2GO/s https://www.eevblog.com/forum/repair/agilent-54810a-infinium-o_scope-possible-updates/ But it’s not clear yet. It is R134 and not R154 (sorry) that must be set to 0 Ohm On the example R137 seems desoldered, on my board there are 0 Ohm, so the explanation is not clear. Should we: 1st Delete R137 2nd Set 0 OHM to R134. I’ll see later, because it’s accessible without the cover cdt |
