Electronics and Signal Processing
The Model 3000TA Trace Oxygen Analyzer uses an 8031 microcon-
troller with 32 kB of RAM and 128 kB of ROM to control all signal pro-
cessing, input/output, and display functions for the analyzer. System power
is supplied from a universal power supply module designed to be compat-
ible with any international power source. Figure 2-6 shows the location of
the power supply and the main electronic PC boards.
