Dear
I got used TDS7104 and It was no problem at first.
I decide to clean and i disassembled it.
The problem was after changing CMOS Battery on MainBoard.
TekScope stuck state continue.
Almost case, It was NVRAM on PPC board.
So, i changed NVRAM on PPC Board
First, it was same.
Next, i set VxWorks boot Parameters using RS232C Communication.
Now, PPC boot seems no problem.
but, Line of "dsyInit" did not go on next.
this symptom is first as i searching web.
do you know this reason?
I assume it was a ACQ Board.
But, we can not any information about ACQ board.
