The core of the analyzer is a microcomputer that controls various internal processes,
interprets data, makes calculations, and reports results using specialized firmware
developed by Teledyne ML. It communicates with the user as well as receives data from
and issues commands to a variety of peripheral devices through a separate printed circuit
assembly to which the CPU is mounted: the motherboard.
