Dear friends, I ask you if possible to help me solve my problem: I have SA HP70000 and a HP70820a that worked perfectly.
At a certain point without having used it improperly an error occurred (7301 ch 1 up bus, wr addr: bit).
I ask you if anyone has info or has had the same problem.
I ask for your help in trying to solve it.
Thanks
Gianni
