Thanks everyone for the great advice! I¡¯m looking into that probe now...
I found a complete service manual, it says for serials below 30,000. I have a newer 465B with SN:B045757, is there much difference in the manuals? I¡¯d guess the procedures are the same and the schematics are different? (Should I find and print a new one, or just reprint the schematics). I was looking for particular sections discussed on other forums and became lost. There are many out there. The 465 and 465B are similar, and the 465B has 2 or more revisions. If I had a newer eye prescription I would have seen that before printing, LOL!
Probes: I have pair of cheap Chinese 1-10X probes and the set that came with my Rigol. Is the auto-set on the probes important to doing the calibration? It calls for 10X probes. The manual is pretty specific with other items; cable length, impedance, T connectors, BNC terminators etc... I have a Chinese DDS sig gen/counter that supposedly is good to 60mHz. What must have equipment needed to do things properly?
So as not to mix up this thread too badly, after I go through the checks in the correct manual I¡¯ll start another. At the moment I¡¯d like to just get this unit fully functional.
Again, I¡¯m new to all of this and really appreciate everyone¡¯s help. This is a great group!
