The processor system contains a MPC680DC Power PC microprocessor that
controls the entire instrument. The processor system also contains FLASH
ROM, system RAM, and interfaces to communication modules, the parallel
printer port, and the floppy disk drive.
The power converter receives 15 VDC (or battery voltage) from the battery board
and generates voltages for the analog and digital circuitry on the main board.
Display Module
The display module consists of a color liquid crystal display (LCD), a display
driver, a pair of fluorescent back light tubes, and a high-voltage back light power
supply.
Front-Panel Board
The front-panel board contains a microprocessor that reads the front-panel
buttons and controls and then sends this information to the processor system.
The front-panel board also generates the probe compensation output signal and
provides an interface to the application modules.
Disk Drive
The disk drive module consists of a 3.5 inch, IBM format, floppy disk drive. The
disk drive is controlled by circuitry on the Main Board.
