FUNCTIONING OF EQUIPMENT
The chapter provides theory of operation on simplified block dia-
gram, functional block diagram, and schematic diagram levels.
Section II of this chapter provides a general and functional de-
scriptions of receiver control operation. Section III provides de-
tailed circuit theory for the reparable assemblies of the unit.
GENERAL AND FUNCTIONAL DESCRIPTIONS
The receiver control basically consists of front panel controls
and instruments, a microprocessor, and input/output (I/O) elements.
The front panel controls and instruments allow the operator to direct-
ly control an intercept receiver. The 6-digit frequency display in-
plays which functions are active. Figure 5-1 is a simplified block
diagram of the receiver control. Figure FO-1 shows the color code
chart for military standard resistors, inductors, and capacitors.
Figure FO-3 is the receiver control wiring diagram and figure FO-4 is
the fan assembly wiring diagram.
The microprocessor scans the front panel controls and interprets
any activated keys and/or associated analog controls. The micro-
processor interprets these data and stores them in its memory, and
also relays these data in proper format to the I/O elements.
The 1/0 elements, which are input and output serial data, clock,
and load strobes go to tile various external devices that interact
with the receiver control . These devices are usually an intercept
receiver, a spectrum display, and a computer.
