My 54845 a fails time base and pattern trigger on self test. I`ve tried all over for a year to find a new or used acqusition board but without any luck. I have no schematics or layouts of components for the unit at all. So it makes it kind of impossible to troubleshoot to. Is there anybody out there who knows this unit well and will be kind enough to guide me in the right direction. Is there a download link for schematics for the 54845 A.
I`ll appriciate any help.
Thank you.
