Replacing Assemblies

This chapter contains the instructions for removing and
replacing the assemblies of the logic analyzer. Also in this

These replacement procedures are organized as though you
are disassembling the complete instrument, from the first
assembly to be removed to the last. Some procedures tell
you to remove other assemblies of the instrument, but do
not give complete instructions. In these cases, refer to the
procedure for that specific assembly for the instructions.
