SERVICE INFORMATION
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 (p/F).
Resistors =
Ohms (i).
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.
The overline on a signal name indicates that the signal performs its intended function when it goes to the low state.
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
Drafting Practices.
Y14.2, 1973
Line Conventions and Lettering.
Y10.5, 1968
Letter Symbols for Quantities Used in Electrical Science and
Electrical Engineering.
