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 (µF).
Resistors = Ohms (Ω).
Graphic symbols and class designation letters are based on ANSI Standard Y32.2-1975.
Logic symbology is based on ANSI Y32. 14-1973 in terms of positive logic. Logic symbols depict the logic
function performed and may differ from the manufacturer's data.
Abbreviations are based on ANSI Y1.1-1972.
Other ANSI standards that are used in the preparation of diagrams by Tektronix, Inc. are:
Y14.15, 1966
Y14.2,
1973
Y10.5, 1968
