DIAGRAMS AND CIRCUIT BOARD ILLUSTRATIONS
Symbols and Reference Designators
Electrical
components
shown
on
the
diagrams
are
in
the
following
units
unless
noted
otherwise:
Capacitors = Values one or greater are in picofarads (pF}.
Values less than one are in microfarads (uF).
Resistors = Ohms (Q)
Symbols used on the diagrams are based on USA Standard Y32.2-1967.
Logic symbology is based on MIL-STD-8068 in terms of positive logic. Logic symbols depict the logic function performed
and may differ from the manufacturer's data.
The following special symbols are used on the diagrams:
& External Screwdriver adjustment.
External control or connector.
Clockwise control rotation in direction of arrow,
eel.
ey Refer to diagram number indicated in diamond,
Refer to waveform number indicated in hexagon.
Connection soldered to circuit board.
