Have you done the mods as pointed by rbaleiro (page 28)?
Have your unit passed self-calibrarion ?
Hi,
Yes, did the mods exactly (and checked on back pages for confirmation)
All the self calibrations passed (HW and USER)
Mine is the EDUX10002A version and I have done the CH1 CH2 and TRIGG(and extra resistors for ext in) mods plus 23 ID for DSO1102A.
Everything works fine except that weird thing on X1 probes. I feel that it might be related to the filter on the diff amp. I've used 47uh and 4.7 pF as others said or maybe when you do the mod the trimmer on the input has to be readjusted? I am not an expert on how the oscilloscope front end works.
Thanks for the time.
