This chapter describes the theory of operation for the logic
analysis system and describes the self- tests. The information
in this chapter is to help you understand how the logic
analysis system operates and what the self- tests are testing.
This information is not intended for component- level repair.
The block- level theory includes the theory of operation of
the logic analysis system in terms of the major subsystems
including:
• CPU subsystem
• PCI board
• MIB (module interface board)
• I/O (input/output) board
• Front panel assembly
