2.3.1 General
The signal processing uses an Intel

microcontroller with on-board
RAM and ROM to control all signal processing, input/output, and
display functions for the analyzer. System power is supplied from a
universal power supply module designed to be compatible with most
international power sources.
The power supply circuitry is on the Power Supply PCB, which is
mounted vertically, just behind the rear panel of the Control Unit.
The signal processing electronics including the sensor amplifier,
microcontroller, analog to digital, and digital to analog converters are
located on the Main PCB, which is mounted vertically, just behind the
front panel of the Control Unit.
