The performance check/calibration that starts on page 5-4 was perfect up to step 16. Check Horizontal and Vertical Displayed Noise on page 5-15. The noise is twice what it should be for the

Hi Frank, Similar to your aquistion, my 2465B was a company scope that lost horiz drive so I paid a few bucks and took a chance on it. Fortunately I had a late friend who repaired HP & Tek products on

A free pdf file can be found on the BAMA site. You can find it by using your favorite search engine. Do you have real probes on those inputs? 10x probes have a resistor that will identify the

Both of those scopes are very worth saving.  The 7904 is my go-to 7000 series scope.  You may want to look to see which ones have similar power supplies to the 7904, and then do a swap, I have a

FWIW, In amongst work, other projects, video games, lost motivation, general apathy, etc... I ended measuring the DC resistance of each transformer winding, simplifying the schematics down to just

Hi, Yes, this could be battery related. First of all check if it is not attenuator and trigger ext cal, that is missing. If it is not calibrated, it will still show up in the self test or the

I submit that your unit is not beyond repair.  Most of the problems are in the preregulator, which is easy enough to fix or replace. Where are you?  If not too far from Los Angeles I'd be willing to
