Dear All,

We are having an HP 8563A spectrum analyser with non working power supply. I have taken it to the authorised service center in India and they returned saying that they do not support this any more.

Can someone share the SMPS schematics for this board? Any service manual also will help.

I could figure out that the SMPS is based on NE5560 chip

Thanks in advance
Paul

Hello Paul,

856xA has been out of support for a long time and the power supply is no longer available.

If you send me a private message I may be able to copy a page or to out of my old CLIP set for you.

Best regards,
