SECTION 8-7B9OP INSTRUCTIONIONDIAGRAMS AND CIRCUIT BOARD ILLUSTRATIONSBOARDSymbols and Reference DesignatorsElectrical 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 ()ILLUSTRATIONSDIAGRAMSGraphic 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 logicfunction 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:Y14.15,1966Drafting Practices.Y14.2,1973Line Conventions and Lettering.Y10.5.1968Letter Symbols for Quantities Used in Electrical Science andElectrical Engineering.The following prefix letters are used as reference designators to identify components or assemblies on the diagrams.Assembly.separable or repairableHHeat dissipating device (heat sinkSwitch or contactorcircuit hoard.rtciheat radiator.etc)TTranstcrmerATAttenuator.fixed or variabinHeglerTCThemmocoupleMotorHYHybrid circuitTest pointBTBatteryConnector slationary portionAssemtly inseparable or non-repairableCapacitor,fixed ar variableKRelayintegrated cireuit,ele.CaCIrcuit breakerInductor.fixed or variableElectron tubeCRDlooe.sicnal or rectitierMeterRVeilage regulator Izener cinde,etc.1DLDelay linePConnector.movable portionWirestrap or cableDSIndicating device (lamnp)0Transistor ar silicon-controlledCrystalSpark Gap,Ferrite beadFuseRes stor.fixed or variahleFLFilterRTThermisto'Plug to E.C.BoardThe following special symbols may appear on the diagrams:Box Identifies PanelStrap or LinkPISControls,Connectors andBALIndicatorsCam Switch+12VClosure Chart5712Modified Component-See(Dot indicates●103R:5tParts List(Depicted in grey,switch closure】mv●z0W1650Kor with grey outline)50-12WPlug IndexSEL Value Selected3+2Vat FactoryR43Refer to WaveformSEL+12V●TPI2ToDIAGRefer to Diagram Number④Test VoltageJ13丁4Coaxial ConnectorInternal7ScrewdriverShieldingAdjustmentQ4-10.5Heat SinkFunctional BlockOutlineDecoupled or FilteredRIO100VoltageAssembly NumberHAMPL-12V34Etched Circuit BoardBoard NameOutlined in BlackPARTIAC AI VERTICAL BOARDVERTICAL AMPLIFIER<②Schematic Nameand Number@Scan by vintageTEK-Your donations help support the museum-vintagetek.org
