Hi guys, newbie here, not sure if this is the right place, id appreciate directions to the right forum.
I recently bought a used hp 54645A off ebay.
It boots ok with no error messages, shows both traces and properly shows the square test signal.
Theres one issue with it - the display seems to freeze when i try to toggle vectors.
After a hard reset the splash screen shows "PANIC - DSP COMMUNICATIONS TIMED OUT".
Also - sometimes the display would boot up jumbled. I reckon the jumbled display is related to the freezes.
no joy with the hp/agilent documentation, but i did get a hold ofo the schematics for the scope, here.
Iv'e included some photos, hopefully they would make up for my non native/professional english.
Has anyone seen this before? any usual suspects?
Thanks,
Nitzan
