Instrumentation SystemSection 111

The Calibrator-Controller Assembly's signalto the c alibration bus may be switched out and substi-tuted by an input fr om the ESE. This input is a 100Hz signal with the pri ma ry purpose of calibratin g thoseFM tele mete r channels that ca rr y frequency-intelligentmeasurement data.

A command fro m the ESE can caus e the singlesideband telem eters to be switched to the calibrationbus in the Calibrat or-Contr oller Assembly. Asweeping 0 to 3000 Hz calibration signal is thenapplied to the bus from the ESE. This 1 V peak-to-peak sig nal sw eeps fr om 3000 Hz to 0 Hz to 3000 Hzin a 10 secon d period.

Application of a pref ligh t calib rati on modecommand causes those FM telemeter channels con-nected t o the YES bus and the NO bus t o be switchedto the calibration bus. This command also allows the

0 to 5 Vdc calibration voltage fro m the Calibrator-Controller Assembly to be completely controlledfr om the ESE.

After the preflight calibration mode commandha s been sent, the 0 to 5 Vdc output is under the com-ple te control of th e ESE. The ESE may sel ect any ofsi x possibl e sig nals to be supplied by the Calibr ator-Controll er Assembly to the calibration bus. Any ofthe five voltage st eps o r a continually stepping voltagemay be selected. Each of the se six signa ls may be ap-plied to the calibration bus for as long as desir ed.

ESE Control

Five switches on the IU Measuring & TrackingPane l provide manual contr ol of TM cali brat ionduring checkout. Using the se switches, inflight TMcalibratio n can be s imulated o r a variety of check-out modes can be selec ted.

Power i s applied to the Calibrator-ControllerAssembly by the TELEMETER CALIBRATOR switch,and verification that power has been applied to the unitis returned to the asso ciated indicator via telemetryo r DDAS.

The MODE s witch se le ct s whether inflightcali brat ion will be simu late d or one of the var iety ofpreflight checkout modes enabled.

The AC-SSB swi tch, in the AC position,enables a 100 Hz calib ration signal to be applied toeac h VCO in the FM tel eme ter s. In the SSB position,it enables a 0 to 3000 Hz calibration signal to beapplied to the single sideband tele meter s. Thisswitch is operable only in the preflight mode.

The PREFLIGHT LEVELS switch operatesonly in the preflight mode and selects the calibrationvoltage level for Calibrator-Controller Assembly toapply to each FM telemeter VCO.

The COMMAND pushbutton causes th e cali-

bration mode that ha s been set up by the fourTELEMETER CALIBRATION switches to be appliedto th e telemetry equipment.

3-5 TELEMETRY COMPONENTS POWERCONTROL

Pr io r to launch, all telemetry components ar emanually ON-OFF controlled fro m th e IU Measuring& Tracking Panel (see Figure 3-4). The componentscan al so be automatically controll ed by the LaunchComputer Complex. All of the re al ys shown in th e IUar e self-latching so they will stay closed aft er um-

bili cal disconnection.When the relays a r e closed, the airborne

components a r e powered by the IU Electrical System.P r i o r to launch, the Electrical System generallyuses facility power instead of the batteries.

Discrete indications of th e status of the air-borne components a r e sent to th e IU Measuring &

Tracking Panel via PCM telemetry o r DDAS. Thesediscrete signals control lights associated with th econtrolling switches.

When necessary during checkout, the Test

Conductor can ensure that rf silence is maintainedby withholding operating power from some of th etelemetry components, This power can be withheldfrom al l telemetry transmit ters , and all telemetersand multiplexers except those needed to transfer datthrough the DDAS coaxial path.

For S-IU-204 only, a command from theSwitch Selector turns OFF operating power to the S1Transmitter. The command i s sent a f t e r the S1Transmit ter ha s ceased to broadcast useful data.This function prevents rf interference with othersystems.

3- 6 MEASURING RACKS POWER CONTROL

The 28 Vdc operating power to the MeasuringRacks and Measuring Rack Selector ca n be appliedautomatically by the Launch Computer Complex o rmanually by the IU Measuring & Tracking Panel (seeFigures 3-5 and 3-6). The power to the MeasuringRacks will remain applied after umbilical disconnec-tion because of latching relays, but power to theMeasuring Rack Selector (and subsequently to thechannel selectors) can only be used during checkout.


91/119

Instrumentation SystemSection I11

One signal through the tele met ry o r DDASpath causes the MEASURING RACKS indicator toshow that power has been applied to Measuring RacksA401 through A407 and A409. Anoth er sign alcauses the MEAS RACK 602A408 ON indicator tolight.

A command fro m the Switch Selector turn sOFF the operating power to Measuring Rack A408.This is done to conserve the airbo rne batter ies. Thecommand is sent during flight, after the me asure -ments going through that rac k have cea sed torepresent meaningful data.

3 -7 MEASURING VOLTAGE DISTRIBUTIONAND CONTROL

There a re two different measuring voltagesyste ms, one in the IU and one in the IU ESE. Bothsys tem s can be automatically c ontrolled by the Launch

Computer Complex or manually controlled from theIU Measuring & Tracking Panel. A voltmeter onth is panel will monitor the voltage of e ith er ofthese distribution systems.

Vehicle Mea suring Voltage

The vehicle measuring voltage originates i n the5 V Supply (see Fi gur e 3-7) and is routed through theMeasuring Distribut ors to the nec ess ary components.This 5 Vdc is used fo r potentiometer trans duceroperating power, in teleme try calibration, and a ssigna l conditioning bias voltage.

The measuring voltage is furnished to thepotentiometer tra nsd uce rs which us e a perce ntage ofthe 5 Vdc as their output signal. In addition to the IUpotentiometer trans ducer s, the measuring voltage is

supplied to those transducer s in other st ages thatfurnish signals to the IU Instrumentation System.

The m easuring voltage is sent to the Cali-brato r-Con trolle r Assembly to be converted intothe telemetry calibration signal.

Measuring voltageis

sent to all MeasuringRacks and distributed to all 20 channels in each Mea-suring Rack. The measuring voltage is used by acand dc ampli fier modules fo r signa l biasing. ACmeasurement signals that ar e normally centeredaround 0 Vdc must be biased at 2.5 Vdc to place themin the ran ge accep table by the tel eme try equipment.

The measuring voltage furnished to F2 and P1Mux is used a s amplitude reference pulses and asfr am e identification pulses.

Measuring voltage is supplied to F1 and F2Telemeters but is not used by these units.

The vehicle measuring voltage is mo nitoredand returned t o the ground by the telem etry andDDAS paths. It can be meas ure d by the vol tme ter

on the IU Measuring & Track ing Pa nel when the BUSswitch is in th e +6D81 position.

Ground Mea suring Voltage

The ground measuring voltage originates in anESE 5 Vdc power supply. This voltage is distributedto measurement re cor der s and other instrumentationequipment that us e it a s a calibration sta ndard voltage.

The voltage i s controlled from the IU Measur-ing & Tracking Pan el and can be mea sured by the

voltmeter on that panel when the BUS switch is in the+6D80 posi tion (+6D810 position fo r S aturn V).

TAPE RECORDER OPERATION

During checkout, the Tape Recor der isoperated manually from the IU Measuring & Track-ing Panel or automatically by the Launch ComputerComplex. During flight it is operated by commandsfrom the LVDC through the Switch Selector.

P ri o r to launch, 28 Vdc power is applied to theTape Recorder by the ESE (see Figure 3-8). ThePOWER and READY TO RECORD indi cat ors will lightindicating that the Tape Recorder is read y for op era-tion. After launch, a command fr om the LVDC willcause the Tape Recorde r to record the outputs of F 1and F2 Telem eters during retro-rocket fire. Nearthe end of IU operatio n, commands fr om the LVDCcause the Tape Rec order to play back its recordeddata fi rs t in re ve rs e and then forward. Duringeithe r playback mode, the data stil l being furni shedby F1 and F2 Tele met ers is not sent to the rf com-ponents.

During prelaunch checkout, the rec or d andrev ers e playback commands can be se nt to the TapeRecorder f ro m the IU Measuring & Tracking Panelthrough the Switch Selector. The indic ators on thepanel a re lighted by sta tus sig nals sent back to theESE via PCM te lem etry o r DDAS.

res et pulse to the LVDA to make a new 40-bit wordavailable (see Figure 3-1 5) . The four 10-bit wordsar e furnished sequentially, in parallel format, to thePCM/DDAS Telemeter at a ra te of twice each PCMframe, or 240 times per second. As the reset pulsefr om the RDM-K ca use s the 40-bit LVDA word tochange at the sam e rate, this gives a sample r ate of240 times per second with each sample representingnew information.

3-1 5 COMMAND AND COMMUNICATIONSYSTEM INTER FACE

In addition to being broadcast through the TMAntennas, the PCM telem etry dat a is also furnishedto the airb orne Command and Communication System(CCS) for tran smis sion to ground receiving statio ns.The PCM data i s s eat t o CCS by two differentmethods: one is the output of the UHF Tr an sm it te rand the othe r i s the NRZ data rig ht out of the PCM/DDAS Tele mete r. In all case s the data is the same,a s it i s the se ri al output from the PCM/DDAS Tel e-meter.

UHF Link

The output of the UHF Tra nsm itt er i s furnisheda s the input to th e three-way PCM Coaxial Switch ( seeFigure 3-16). The output of th is sw itch is controlledthrough the Switch Selecto r by the pr ogr am of theLVDC. Two of the output paths go to sepa ra te ci r -cuits within the PCM Directional Antenna. Thesetwo cir cui ts allow an output beam s pr ea d of 40

degr ees or 70 degrees. The thir d output path fromthe PCM Coaxial Switch goes through the Hybrid Ringand on to the CCS/PCM Omnidirectional Antennas.The choice between these t hre e paths is governed bythe distance of the IU fr om Ear th.

CCS Down-Link

The NRZ output of the PCM/DDAS Telemeteris also furnished directly to the tr ansm it section ofthe CCS Transponder a s a modulation source. Thistra nsm it section ge nera tes the CCS down-link rfca r r i e r t hat is sent to the CCS Power Amplifier.The amplified carrier is next furnished to the CCSCoaxial Switch from where it follows a path similarto the UHF telemetry c ar ri er described in the pre-ceding para grap h. An inhibit signal fr om the SwitchSelector can tur n OF F the down-link signal to elimi-nate intwference between the CCS Transponder andsimi lar transponders in the spacecraft.

CCS Up-Link

Interrogation pulses and discr ete commandsa r e furnished to the receive section of the CCS Tr ans -ponder through the CCS Receiving Antennas and CCS

Power Divider. This up-link signal supplies data tothe transm it section and is al so demodulated for useby the Command Decoder. This audio signal is de -coded by the Command Decoder and furnished to theLVDC/LVDA to initia te a var iet y of functions. Thecommand verifi cation output from the Command De-coder is sen t back to the ground station through PCMtelem etry . Receiving station equipment com paresthe command verification signal to the command thatwas actually sent to ensure that the proper commandwas received by the IU.

3-16 D ATA F O R M AT T I N G

Th e data format is th e relationship of the te le-metry channels within th e output of each of th e te le-meters . This relationship is determined by th e con-figurations of th e multiplexers and te l eme te r s used

in the Instrumentation System. Th e output of aparticular te lemeter unit ma y consist of data channelsthat a r e time-shared, frequency-shared, o r a com-bination of both. The following paragraphs explainthe data formatting character is t ics of each of th ecomponents and list th e data format for each Inst ru-ment Unit.

By design, the data form at can easil y bechanged at any time prior to launch. The data form atsgiven in this manual are for training purposes only.To ens ure accura te information, consult the appropri-

ate I P&C and other engineering documentation.
