HP54510A Power Supply

[[email protected]]

I've got an HP54510A scope with a dead power supply.
Agilent no longer supply the PSU (HP P/N 0950-1879).
The same supply was used in all HP 5450X and 5451X scopes.

It was originally made by Computer Products Power Conversion of Hong
Kong (P/N XL131-3604E).

It's all discrete components, so it should be possible to fix. Does
anyone have a schematic?

Does anyone have any HP documentation which shows what supply voltages
the 54510A uses so that I can substitute a modern supply?

It seems a shame to scrap a 1 GS/s scope.

Cheers
TW

Hello Ted,
OK, your post is four years old, but perhaps you still need some information.

My HP54510A stopped working suddenly today, because of a power supply failure. It's the reason why I searched informations on Internet and found your post.
The power supply is exactly the same as yours, Computer Products P/N XL131-3604E.

Finally I managed to repair, and the scope seems to work again.
I could now measure the voltages at the outputs of the power pupply if you are still interested.

Regards,
Pascal

HP Oscilloscope Power Supply failure

Hi, I have the same problem with my power supply P/N 0950-1879.
How did you go about fixing it?
