Digital Control Section
All the internal functions are controlled from the front panel through the use of a built-in
microcomputer. The microcomputer uses an internal bus to receive or produce all communication or
control to any section of the analyzer.
Power and Cooling Section
The main power supply provides almost all the regulated voltages required to operate the unit. The
display section provides the high voltage necessary for CRT operation.
The cooling system allows fresh cool air to be routed to all sections of the unit in proportion to the
heat that is generated by each section.
SPECTRUM ANALYZER FRONT PANEL CONTROLS, INDICATORS, AND CONNECTORS
This section will describe the function of the front panel controls, indicators, and connectors. For a
complete description of each function, refer to table 6-1 while reviewing the front panel in figure 6-43.
The numbers located in column 1 of table 6-1 equate to the same numbers found on the front panel of
figure 6-43. Because most operational functions of this spectrum analyzer are microprocessor-controlled,
they are switch-selected rather than adjusted.
