The digital control functional group consists of the following assemblies:
• A1 front panel
• A2 front panel processor
• A9 CPU
•A10 digital IF
• A16 rear panel
• A18 display
• A19 GSP
• A27 Inverter
These assemblies combine to provide digital control for the entire analyzer. They provide
math processing functions, as well as communications between the analyzer and an
external controller and/or peripherals. Figure 12-3 is a simplified block diagram of the
digital control functional group.
