TRH1KE_3.doc3.28-Jul-99 11.0 GENERAL INFORMATION1.1 INTRODUCTIONThe Acrodyne TRH/1KE Television Transmitterbroadcasts C3F visual and F3E aural emissions onany single television channel between 174 and 230MHz at a transmitter output level of 1 kilowatt peakof sync visual and one hundred watts average auralpower. The units uses intermediate frequency (IF)modulation and combined visual and aural carrieramplification throughout.The entire transmitter is contained within a single19 inch wide cabinet.1.2 DESCRIPTIONRefer to the block diagram included with thedrawing package.The TRH/1KE may be broken down into threemajor sections. They are 1) Exciter, 2) IntermediatePower Amplifier (IPA) and 3) Final Power Amplifier(PA) and associated control circuits and powersupplies.The transmitter’s program video signal pathbegins with the Video Sync Automatic Gain Control(AGC) printed circuit board within the VideoProcessor Chassis. Video AGC is used to stabilizethe program video signal sync region againstvariations in the signal supplied to the transmitter.The Video AGC output signal is then connected tothe Video Corrector printed circuit board within theprocessor chassis. The Video Corrector is used toprovide adjustment of the transmitter differentialgain/differential phase characteristics and for syncpulse amplitude adjustment.The processed video signal from the VideoProcessor Chassis is routed to the Exciter Chassis andthe modulator circuit where it amplitude modulatesthe visual intermediate frequency carrier operating at45.75 MHz CCIR M/38.9 MHz CCIR G. Themodulated carrier is then passed through a SAW(Surface Acoustic Wave) filter with group delaycorrection to provide the proper lower sideband andgroup delay performance.The transmitter’s program aural signal pathbegins directly with the Exciter Chassis and the auralmodulator circuit. Both balanced and unbalancedaural inputs are provided. These inputs frequencymodulate an aural carrier, operating at 4.5 MHzCCIR M/5.5 MHz CCIR G, that is then converted toan IF carrier frequency of 45.75 MHz CCIR M/33.4MHz CCIR G.The three signal inputs to the IF ProcessorChassis connect first to the Aural Corrector Boardwhere signals for correction of vision to sound cross-modulation are generated. The three signals out ofthe Aural Corrector Board are connected to theIntermodulation (IM)/Incidental Carrier PhaseModulation (ICPM) Corrector board where they actto provide correction for inband intermodulationdistortion and incidental carrier phase modulation.The separate vision and sound IF carrier outputs fromthis board are routed to the Visual/Aural Combinerboard and mixed to create a composite IF signal. Thecomposite IF signal is then connected to the IFLinearity Corrector circuit board, also within the IFProcessor Chassis. The IF Linearity Corrector boardcontains a double break point diode network that isused to correct primarily for transmitter luminance(low frequency) non-linearities. The IF LinearityCorrector output is the output of the IF ProcessorChassis.The IF Processor Chassis output is connectedback to the Exciter Chassis at the Transmit AGCinput. The Transmit AGC functions to automaticallylevel the transmitter output power, with the set pointof the Transmit AGC being set by a potentiometer onthe modulator section. The leveled IF signal out ofthe Transmit AGC connects to the up convertersection within the Exciter Chassis.Upconversion of the IF signal to the desired RFoutput frequency takes place in the double balancedmixer in this section, in conjunction with theupconversion local oscillator, also contained on theprinted circuit board. The RF output of the mixer ispassed through a bandpass filter for removal ofunwanted mixer produces and then amplified to anominal ten milliwatt level. The ten milliwattamplifier output is the output of the Exciter Chassis.The nominal ten milliwatt output of the ExciterChassis is routed to the One Watt Amplifier Modulemounted on the front of the transmitter between theoutput amplifiers. The One Watt Amplifier containstwo RF devices operating in class A mode. The OneWatt Amplifier output connects to the IntermediatePower Amplifier (IPA) Chassis.The IPA stage is contained in a single drawer andcontains two parallel sections each of two RF devicesin series. The input signal to the chassis is split intotwo and then amplified. The two separate amplifieroutput signals are each applied to quadrature typesplitters to create four separate output signals each ofabout 10 watts in power.The four IPA output signals are each connectedto separate 350 watt amplifier stages. The 350 wattamplifier stages are mounted together in pairs to forma 650 watt amplifier drawer. There are two suchdrawers used in this TRH/1KE transmitter. Each 350watt amplifier section contains a single device stagedriving a second stage of two devices in parallel. The

TRH1KE_3.doc3.28-Jul-99 2output signals from each of the 350 watt amplifiers ina 650 Watt Amplifier Drawer are combined using aquadrature type power combiner mounted separatefrom the drawer. The output signals from the two2x350 watt combiners further combined using anotherquadrature combiner.The resulting 1100 watt output signal is routedthrough a circulator for protection of the transmitteragainst high VSWR. The circulator output isconnected through a directional coupler section formonitoring of the RF output power. The coupleroutput signal is routed out of the cabinet and througha high power band pass filter for removal of the out ofband intermodulation products generated by thetransmitter.

Thefollowing instructions and suggestions are not meantto be the only way for a correct installation.However, any variation from recommendedinstallation procedures given may be in violation ofAcrodyne warranties. Please consult the FactoryField Service Department before attempting anyalternate methods of installation.ACRODYNE INDUSTRIES, INC.FIELD SERVICE DEPARTMENT516 TOWNSHIP LINE ROADBLUE BELL, PA 19422 USATELEPHONE: (215) 542-7000 OR (800) 523-2596 (OUTSIDE PA)FAX NO: (215) 540-5837E-MAIL: ACROINFO@ACRODYNE.COMINTERNET: ACRODYNE.COM2.2 UNPACKING AND INSPECTIONMechanical assistance will be needed to movethe unit due to its weight. Due care must be used tounpack the unit. Do not use blows with a hammer orpower chisel to unpack the unit. A general purposewrecking bar and claw hammer is all that is needed todisassemble the shipping container.WARNINGUSE CARE IN CUTTING THROUGHRESTRAINING STRAPS USED TO SECURETHE EQUIPMENT. THESE STRAPS AREUNDER HIGH TENSION AND THEIRRELEASE CAN BE EXPLOSIVE IN NATURE.DO NOT STAND DIRECTLY IN FRONT OFANY STRAPPING WHILE CUTTINGTHROUGH IT.After the equipment has been unpacked, it shouldbe inspected for any damage that may have resultedduring shipment.Inspection Checklist1. Front of Transmitter: Check for warpage, dents,etc. All panels should have all screws in place.Doors should unlock and open freely.2. Meters, lenses, bulbs, etc: Inspect all meters forcracks and damage and check all lenses andLEDs for damage.3. Rear of Transmitter: Check rear door lock foroperation. Open rear door and look for loosehardware or components on the floor of thecabinet.4. Top of Transmitter: Check the RF output flangefor damage. Check electrical entrance point andRF/video input BNC connector and audio inputterminal barrier (where used).5. Inside of Transmitter: Check for followingitems:650 watt amplifier cooling blowers, impellershould rotate freely by hand.All wiring harnesses for security.If the unit is damaged electrically ormechanically, notify the carrier andACRODYNE INDUSTRIES, INC. immediately.NOTESOME ASSEMBLIES MAY HAVE PACKINGMATERIAL USED TO MECHANICALLYSTABILIZE THEM DURING SHIPMENT. ANYPACKING MATERIAL USED IS LABELED ASSUCH AND SHOULD BE REMOVED AT THISTIME.2.3 SITE CONSIDERATIONSThe transmitter site/location choice is of utmostimportance. To ensure long life of your transmitter,the following list is an important checklist ofconcerns that must be known and continuouslymonitored before, during and after installation andthroughout the life of the transmitter. Abuse of anysophisticated electronic equipment can only lead toshort operation life and/or expensive repairs. Becautious of the following:1. Maintain a clean and dry building/enclosure.2. Ensure a stable electrical supply. Provide asecure and stable earth ground for the transmitterand any AC transformer used.3. Secure the transmitter space to preventunauthorized entry.4. Avoid temperature extremes. A maximum roomambient of 25°C is recommended. It isrecommended that the cabinet top exhaust beducted outside. Back pressure presented to thecabinet exhaust by the external duct work mustbe kept to a minimum. It is preferable to use anassist fan in the exhaust duct work to provide anegative pressure to the cabinet exhaust. If thisis done it is very important to provide adequateroom intake air. The cabinet top exhausted airvolume is approximately 900 cubic feet per

TRH1KE_3.doc3.28-Jul-99 8minute (CFM). The building intake must allowfor this plus some margin. In addition the airintake must be provided with adequate filtering.The area of the intakes should be large enough tokeep the intake air velocity below 300 feet / 100meters per minute. This will allow the intakedirt/dust filters to capture the maximum amountof dirt possible. With the exhaust volume at 900CFM the air intake area should be not smallerthan 3 square feet.5. The units should sit on a flat, level surface.Cement floors should be sealed or covered with avinyl tile to minimize dust and facilitate cleaning.2.4 CABINET INSTALLATIONWhere possible locate the transmitter cabinet inclose proximity to the intended RF transmission linesand AC MAINS power disconnect to minimize theinput and output connection runs.Connect the brass grounding bolt, located at therear of the transmitter base, to the site ground system.This is best accomplished with copper strapping ortinned copper braid.WARNINGPOOR GROUNDING OF THE TRANSMITTERMAY CAUSE SEVERE INJURY OR DEATH IFA FAULT SHOULD OCCUR.When the transmitter has been shipped with the650 Watt Amplifier Drawers removed from thetransmitter cabinet, reinstallation of the modulesshould be done following a few simplerecommendations.1. Though it is possible for one person to handleand install a drawer it is recommended that twopersons perform the procedure. Dropping adrawer would prove to be a very expensiveaccident.Each drawer has a unique position in thetransmitter and is identified by a number on boththe drawer and that position within the cabinet.Make certain that the drawers are put into theproper slot corresponding to their number labels.2. One of the pair of cabinet mounted slides (onepair for each drawer) should be adjusted to itsfully extended and locked position, and thedrawer slide has been mated properly, the otherhalf of the cabinet pair can be pulled forward andattached to the drawer.3. The spring metal tabs on either side of the slidesare pushed in to unlock the slides and allow thedrawer to be pushed in.4. There are seven connections that need to bemade to each drawer, four coaxial cableconnections and three harness cable connections.Each drawer is to be connected to a distinct cablegroup that branches from the cabinet wireharness, at the top of the cabinet. The left mostdrawer to the left most cable group etc.The N type RF output connections should bemade finger tight, while the SMA type RF inputconnections should be made wrench snug. A 5/16inch wrench is used.The all black control cable connector is keyedsuch that improper orientation is impossible. Theknurled locking ring should be rotated fully to lockthe mated connector in place.Special attention should be given to properlyconnecting the two high current connectors for themodule. This connector is blue and black. The bodyof the high current connector is keyed to ensureproper mating. The harness cable end plug is insertedin the drawer mounted jack and twisted clockwise tolock it in place. The silver locking tab should snapinto place to lock the entire connector. To verify thisconnector is properly in place, grasps the outerconnector shell and tug outward. A properly madeconnection will remain together.2.5 EXTERNAL CONNECTIONS2.5.1 AC MAINSCAUTIONVERIFY THAT THE AC MAINS CONNECTEDTO THE TRANSMITTER IS THE SAME ASINDICATED ON THE LABELING ATTACHEDTO THE CABINET TOP JUNCTION BOX.1. The transmitter AC MAINS input connectionpoint is within the junction box located on thetransmitter cabinet top. Conduit is to bemechanically fastened to the outside of thecabinet top junction box.2. Refer to the Electrical Specifications in section1.3 for the recommended service ampacity forthe mains configuration of the transmitterdelivered. For a single phase service configuredtransmitter, the line-to-neutral voltages must bothmeasure between 107 and 132 VAC. For a threephase service configured transmitter the phase-to-phase voltages must measure within 5% ofeach other.For three phase configured transmitters,there is a three phase power monitor thatmonitors the presence, and absolute and relativevoltage levels. A loss of phase, a low overallvoltage, or a phase-phase voltage imbalance willtrip the monitor and keep the transmitter fromturning on. Once the AC MAINS have been

TRH1KE_3.doc3.28-Jul-99 9connected, apply mains power and verify that theTRIPPED indicator on the phase monitor, visiblethrough the front circuit breaker panel, is not on.If the TRIPPED indicator is on, verify that theAC MAINS power is present at the øA, øB, øC,terminal inputs. If the voltage is not thereinvestigate AC MAINS wiring to the monitor andtake corrective action to connect the ACproperly. If the voltage is present the TRIPPEDindicator means that the proper A to B to C phaserotation is disturbed. Disconnect and swap anytwo input AC MAINS lines and recheck themonitor. Repeat as necessary to cause theTRIPPED indicator to be off.3. Connect the brass grounding bolt located at therear of the transmitter base to the site groundingsystem. This is best accomplished with copperstrapping or tinned copper braid.WARNINGPOOR GROUNDING OF THE TRANSMITTERMAY CAUSE SEVERE INJURY OR DEATH IFA FAULT SHOULD OCCUR.2.5.2 OUTPUT TRANSMISSION LINE ANDANTENNARefer to the application drawing supplied.A bandpass filter is supplied that must bemounted external to the transmitter cabinet.Dependent on optional equipment purchaseddirectional couplers, patch panels and dummy loadsmay also need to be installed. Due to variations ininstallation, elbow connections connecting coaxiallines, etc. are not normally provided, unlessspecifically ordered.The installation may vary from that indicated inthe application drawing, through it is highlyrecommended that the bandpass filter and directionalcoupler be placed immediately at the cabinet output.The actual lengths of inter-connecting pieces is leftup to the installer's discretion.CAUTIONHANDLE ALL COAXIAL COMPONENTSWITH CARE. ANY DAMAGE WILLADVERSELY AFFECT THE TRANSMITTEDSIGNAL. ALL COAXIAL COMPONENTSSHOULD BE SUPPORTED AT THE FLANGES.SECTIONS LONGER THEN TEN FEETREQUIRE ADDITIONAL MID SUPPORT. ALLFLANGES SHOULD HAVE EVERY BOLTHOLE SECURED WITH THE PROPERHARDWARE. COAXIAL COMPONENTSMUST NOT BE USED TO SUPPORT OTHERSTRUCTURES.Bandpass FilterAn external bandpass filter is supplied. It mustbe mounted to minimize any stress placed on theinput and output connectors. It must not be hung bythe connectors. Use the mounting flanges that are apart of the filter body.A six foot length of Heliax cable is provided toconnect between the transmitter cabinet type N RFoutput and the filter type N input.Directional Coupler (Optional)If an external directional coupler is supplied itshould be mounted directly on the transmitter filter 1-5/8” flange RF output. The coupler monitors theforward and reflected output power of the transmitter.NOTEANY DIRECTIONAL COUPLER SECTIONSMUST BE INSTALLED WITH THEIR "RFINPUT" DESIGNATED END POINTINGTOWARDS THE TRANSMITTER RF OUTPUT.THE "RF OUTPUT" DESIGNATED END MUSTPOINT TOWARDS THE ANTENNA.Patch Panel (Optional)The patch panels were designed to ease thechanging of the transmission line from the antenna tothe dummy load for maintenance purposes. Includedon the panel(s) is a series of electrical interlocks toprevent RF transmission into an open transmissionline. If a patch panel has been included as part of thistransmitter, electrical harnesses are provided for thispurpose.Connect the wire harnesses to the correspondingterminals on the patch panel(s), and connect the otherend to the transmitter cabinet top terminal barrierlabeled for patch panel usage.Dummy Load (Optional)The patch panel may have two additionalpositions to accommodate a high power dummy loadand a small signal dummy load.The high power load may include an RF sampleport and a through-line wattmeter. The small signalload is used for RF sweeping.The location of the high power load is notcritical. Consideration should be given to theelectrical needs as well as the generated heat from theload. Short runs of coaxial cable are desirable. Thedummy load should also be interlocked to preventdamage, and may be connected through the patchpanel interlock. All the interlock switches should beserially connected and present a closed circuit innormal operation. A fault condition should presentan open circuit.

TRH1KE_3.doc3.28-Jul-99 10AntennaThe antenna and connecting RF transmissioncable return loss must be verified before any RFsignal transmission is attempted. This involveschecking all RF connections and verifying the"Return Loss" of the transmission line/antennacombination.A return loss of 26dB (VSWR = 1.1:1) is usuallyrequired from the visual carrier to +2.75 MHz from+2.75 MHz to the upper band edge and from visualcarrier to the lower band edge return loss maydegrade to 20dB.Obtaining a return loss better than 26 dB acrossthe 6 MHz bandwidth is routinely accomplished. Ifthere is any uncertainty as to the quality of thetransmission match, the line should not be attacheduntil such time as the line has been proven to meetthese specifications.2.5.3 AUDIO/VIDEO INPUTSThe baseband audio and video signals for thetransmitter are to be connected to the transmittercabinet top. The program video input to thetransmitter is a BNC connector and is labeled asPROGRAM VIDEO IN. This is a 75 ohm terminatedconnection; there is no loop-through provision.The input for balanced monaural programming isthe three pin XLR connector on the cabinet top. Thisis labeled as BALANCED AUDIO INPUT. Pinlocations two and three are for the signal lines.Ground/shield is pin one.Note that if your transmitter has been suppliedwith a BTSC stereo generator installed the cabinettop has been provided with two XLR connectors, onefor each of the left and right channel baseband audioinput signals.Composite BTSC (stereo aural) fed from anexternal stereo generator is to be connected to theBNC connector labeled UNBALANCED AUDIO IN.Note that the both the unbalanced and balanced audioinputs are simultaneously active at the modulatortherefore both audio inputs cannot be driven at thesame time.Audio pre-emphasis may be selectively appliedto the AUDIO input signal by selecting the properposition of switch S2 on the Modulator Board. Referto the modulator drawings included with theillustration section for the location of S2.

TRH1KE_3.doc3.28-Jul-99 113.0 OPERATION3.1 INTRODUCTIONThe information in this section covers the properturn on and turn off procedures to be followed forproper operation of the transmitter.3.2 OPERATING PROCEDURESCAUTIONA KNOWN GOOD 50 OHM TERMINATIONOR ANTENNA SHOULD BE CONNECTED TOTHE EXCITER OUTPUT BEFORE THE TURNON SEQUENCE IS BEGUN. ALLINTERSTAGE CABLING MUST BE IN PLACETHROUGHOUT THE EXCITER SECTION.3.2.1 MANUAL TURN ON1. Set all cabinet circuit breakers to OFF. Set theExciter RF Control switch to OFF.2. Set the transmitter Control Logic drawer StartUp Control switch to the MANUAL-OFFposition. Set each of the 650 Watt PA DrawerAMPLIFIER CONTROL switches and the IPAChassis AMPLIFIER CONTROL switch to theircenter OFF position.3. Remove the front panel screws holding theExciter Chassis in place. Pull the drawer forwardenough to locate the POWER, R84, and GAIN,R110, adjustment potentiometer access holes.4. Set the cabinet AC MAINS switch to ON. Checkthe +24 volt power supply reading on the ExciterChassis. With program or test signal videoconnected to the transmitter cabinet top ExciterVIDEO LOSS LED should be off. If the LED ison, check for video input, and chassisinterconnect coaxial cables to the Exciter toobtain a connection of a video signal to theExciter and cause the LED to be off.5. Place the Control Logic START UP CONTROLswitch into the AUTO position. Place the 650Watt Amplifiers and IPA Chassis AMPLIFIERCONTROL switches into their AUTO positions.The 650 Watt PA Drawer current meters shouldall indicate at the "Io", quiescent current mark onthe meter scale. If no current meter reading isevident, check module meter for voltageindication. 28 VDC should be indicated in eachposition. If there is no voltage displayed or it islow, return both control switches to OFF, switchOFF the AC MAINS switch and verify theconnections to the 650 Watt PA Drawers fromtheir cabinet harness connections. The IPAcurrent meter should indicate 6 amperes.6. While observing the transmitter Control Logicmultimeter PEAK VIS POWER % position,place the Exciter RF CONTROL switch into theAUTO position. Indicated output shouldincrease to 100%. Adjust the Exciter POWERcontrol, R84, as necessary set the RF outputpower to 100%.7. Check the AURAL and REFLECTED powermeter positions and compare these readings withthe factory test data supplied with the transmitter.8. Check the Exciter Chassis AGC voltage meterreading and compare with the factory test data.A reading of about 15 (midscale) on the 0 to 30volt scale is nominal. An indication less thanmidscale means there is insufficient IF driveover-range while an indication greater thanmidrange means there is more than the optimalamount of IF drive over-range. To set the properamount of over-range slowly adjust the ExciterGAIN potentiometer as required to produce amidscale AGC meter reading.3.2.2 AUTOMATIC AND REMOTE TURN ONMaster control of the transmitter turn on/turn offis through the Control Logic printed circuit board.It is the function of the Control Logic to initiatethe various subsection START UP sequences and tomonitor the subsections for their respectiveTRANSMIT READY signals.For logic control purposes, the transmitter isbroken into amplifier subsections. Each amplifiersubsection is self contained in the sense that it willmonitor itself with respect to proper application ofsupply voltages and fault conditions. Fault conditionswithin any particular subsection will be attended to bythat subsection. Each subsection is configured torequire the application of a ground to initiate theSTART UP sequence within that section. When asubsection is ready for RF drive (no faults, allvoltages normal, etc), that subsection provides aground level signal back to the Control Logic that is,the subsection, is TRANSMIT READY.For this transmitter the Intermediate and 650Watt Power Amplifier drawers are treated as a singleamplifier, even though each has its own ControlLogic PCB.The transmitter Control Logic gives a STARTUP command to both sections as a parallel command.The Control Logic portions of both of theseamplifiers will then command the power supply toturn on. As there is a single supply for both thesestages, both stages must be operating properly to turnon the power supply. A thermal fault in either stagewill cause the power supply to turn off during theover temperature condition.

TRH1KE_3.doc3.28-Jul-99 12The Control Logic itself may be instructed toinitiate START UP through a number of ways. TheVIDEO SENSE indicator from the Exciter may beselected to control when PCB terminals E1 and E2are connected. This may be overridden by the actionof the contacts of relay K1. K1 is in turn controlledby remote control systems attached to the transmittercabinet REMOTE INTERFACE TB1301 (see manualsection 3.4). The highest priority control for thetransmitter is the START UP CONTROL switch S1.The AUTO position is selected to permit VIDEOSENSE or remote control operation. To permitremote only operation, PCB terminals E2 and E3 areconnected, bypassing the VIDEO SENSE control.The START UP CONTROL signal supplies alogic low level at U2 noninverting input, causing U2output at pin 1, high turning on each of four sectionsof a high current transistor array, U1. One or more ofthese array sections is used to signal the varioustransmitter subsystems to begin their respective startup cycle.The "TRANSMIT READY" indicator outputsfrom the various transmitter subsystems return to theControl Logic PCB as logic low levels into U4A andU4B. These two inputs are combined in U3 toprovide an RF ENABLE control back to the ExciterChassis. This RF ENABLE control is active whenlow. This also causes the Control Logic front panelRF ENABLED LED to light.For automatic operation, transmitter turn on ofall power supplies can be accomplished with theSTART UP CONTROL switch on the transmitterControl Logic drawer if all other control switches arelisted below.RF Converter RF Control/AutoIF Amplifier/AGC ONTransmitter Control Logic Start Up Control/AutoAmplifier Drawers Amplifier Control/AutoFor remote control of the transmitter,interconnections are made to the 25 pin D-sub remotecontrol connectors positioned on the cabinet top.Refer to the Remote System Connections listing inthe illustration section.3.2.3 EQUIPMENT TURN OFFThe transmitter may be turned off by removal ofthe input video, if all CONTROL LOGIC controlswitches are in their AUTO position. Alternately, theSTART UP CONTROL switch may be placed intothe MANUAL OFF position.The remote control turn off feature is onlyfunctional with the START UP CONTROL switch inthe AUTO position, as the remote turn off circuit is inseries with the AUTO circuit control line. Thisallows manual control of the transmitter to beexercised regardless of remote control system status.

TRH1KE_3.doc3.28-Jul-99 135.0 MAINTENANCE5.1 INTRODUCTIONProper procedures for maintaining the transmitterare provided to ensure continued safe operation of theequipment.5.2 RF POWER METER CALIBRATION ANDAGC SET POINT ADJUSTPower calibration of the transmitter should beperformed on a regular basis to ensure properoperation both under regulatory agency rules as wellas transmitter specifications. It is recommended thata wattmeter line section be installed at the time ofequipment installation to be used as a backup powerindicator as well as a reference for power calibration.1. The transmitter should be connected to asubstantially resistive load/termination, rated tohandle on an average basis, the full peak powerrating of the transmitter. In both cases, anyfilters supplied with the transmitter must beincluded in the output circuit of the amplifierbefore the measurement point. The wrap aroundAGC for the transmitter must be defeated bymanually adjusting the Exciter board poweradjust potentiometer R84 clockwise, until theyellow status LED on the Exciter board goes onor the transmitter power reaches 110%. Use gainpotentiometer R110 to reset transmitter outputpower to the desired level. Remove the auralcarrier by switching the Aural Corrector BoardAURAL CARRIER switch to the OFF position.The IF Processor Drawer must be pulled fullyforward to access this switch.2. If an Acrodyne supplied coupler section is to beused for power calibration, a microwave powermeter will be necessary. The coupling sectionsare factory calibrated against known standardsand the specific coupling values are dependenton transmitter output power.3. Using a directional wattmeter, any plug-inelement selected should provide a maximumdeflection of the meter to minimize metermovement errors. The visual only power must bemeasured under the specific conditions of:a. Visual carrier only, aural carrier off. Turnoff the aural carrier using the Exciter Chassisfront panel Aural Carrier ON/OFF switch.b. Sync and blanking level video only (blackpicture) with a sync pulse amplitude of .287volts CCIR M (40 IRE)/.30 volts CCIR B/G.4. The transmitter peak visual power rating ismultiplied by the conversion factor of 0.595 forCCIR M and .57 for CCIR B/G to obtain theaverage reading that will be displayed on thewattmeter.ex: this 1,000W (peak of sync) transmitter willdisplay an average power of (1,000W x0.595) or 595 watts average power under thespecific conditions noted when transmittinga CCIR M standard signal. It must beremembered that it is the average power thatwill be displayed.5. Set the proper visual power level using theExciter gain pot R110. With the visual powerlevel now established re-apply the aural carrierby switching the IF Processor Drawer AURALCARRIER switch to the ON position. On theAural Corrector Board adjust the AURALPOWER LEVEL potentiometer R81 clockwiseuntil a minus 8 dB aural to visual carrier ratio isachieved as indicated on a spectrum analyzerdisplay. Now adjust the AURAL OVERRANGEpot R111 until the aural carrier level is restoredto -10 dB. The Aural Corrector Board yellowLED should be on as seen through the AURALCARRIER ON-OFF switch access hole.6. When both levels have been set, the transmitterRF POWER MONITOR ASSEMBLY, meterdrive levels can be adjusted to provide accuratepower meter indications. There is a single inputlevel adjust to each of the three meteredfunctions. Refer to assembly drawing 22207217and associated board schematic for adjustmentlocation.The PEAK VISUAL FORWARD POWERdisplay on the CONTROL LOGIC chassis shouldbe monitored while adjusting R24 on the powermonitor board.The AVERAGE AURAL FORWARD POWERdisplay on the CONTROL LOGIC chassis shouldbe monitored while adjusting R2 on the powermonitor board.The AGC SAMPLE output of the power monitorboard at TB2-11 should be monitored with aDVM while adjusting R46 on the power monitorboard. R18 should be adjusted to achieve a 2.5VDC AGC SAMPLE reading, at the powermonitor TB2-11.7. On the Aural Corrector Board adjust the AURALOVERRANGE pot R111 until the aural carrierlevel is returned to minus 8 dB. Now adjust theAURAL POWER LEVEL potentiometer R81until a minus 10 dB aural to visual carrier ratio isachieved as indicated on a spectrum analyzerdisplay. The Aural Corrector Board green LEDshould be on as seen through the AURALCARRIER ON-OFF switch access hole.

TRH1KE_3.doc3.28-Jul-99 14NOTETHE SYSTEM RF METERS FOR AURAL ANDVISUAL POWER ARE NOW PROPERLYADJUSTED. THE AUTOMATIC GAINCONTROL FOR THE AURAL CARRIER ISCALIBRATED TO BOTH THE VISUAL ANDAURAL METER CALIBRATIONS. DO NOTRE-ADJUST THE AURAL METERADJUSTMENT R6 WITHOUT REPEATINGSTEPS 4THROUGH 6. THE AURAL CARRIERRATIO MAY BE ADJUSTED WITH R81 ONTHE AURAL CORRECTOR BOARD IF ACHANGE IN CARRIER LEVEL IS DESIRED.8. The reflected (or reverse) power meter can nowbe calibrated. First, adjust output powerdownward using the Exciter GAIN control R110to achieve a 10% power indication from thePEAK VISUAL FORWARD POWER meterposition, then reverse the forward and reflecteddetected RF signals at the RF Power MonitorAssembly J21 and J2 connectors. . The forwardcoupler port is now attached to the reflectedpower input port, J72, of the power monitorboard. The REVERSE POWER display on theCONTROL LOGIC chassis should be monitoredadjusting on the power monitor board. Set for a10% reverse power indication. Note that thereverse power meter scale is expanded forincreased resolution.9. Return the detector diode assemblies to theiroriginal position, and readjust R110 for an outputpower indication of 110%. Reset output powerto 100% meter indication using POWER controlR84.5.3 VIDEO AND IF PROCESSORADJUSTMENTSVideo Sync AGC AdjustmentsThe Video Sync AGC board needs noadjustments in normal operation. Out of servicechecks of the operation of the board would be:1. Verify that the output video blanking level is at 0volts DC. Use potentiometer R18 to adjust asrequired.2. Verify that the output video amplitude is one voltpeak to peak for an input signal of one volt peakto peak. Adjust potentiometer R14 to adjustoutput level as necessary.3. Verify that the video is as flat as possible throughthe board using a multiburst video test signal or avideo sideband signal generator. Adjustcapacitor C9 to optimize flatness.Video Corrector AdjustmentsRefer to drawing 22708899.The Video Corrector has been adjusted at thefactory to provide optimum performance at the outputpower level specified for the transmitter. In normaloperation, there should be no need to make grossadjustments to this circuit. If the output power levelof the transmitter is changed, it will be necessary toverify the performance of the differential phase andgain parameters and adjust the Video Corrector tooptimize those parameters. Under no circumstancesshould the Video Corrector circuits be adjustedwithout the proper monitoring equipment. Thisincludes a good quality TV demodulator, videowaveform monitor, and vectorscope. Do not adjustany corrector controls unless you have the properequipment to monitor the effects of the controladjustment.When making adjustments the differential gainshould be corrected first, followed by the differentialphase. This procedure will produce the best resultswith the fewest readjustments.There are four separate, independent differentialgain correction circuits. The circuits associated withdiodes CR8 and CR9 will provide a positivedifferential gain correction while those associatedwith diodes CR10 and CR11 will provide a negativedifferential gain correction. Potentiometers R67,R72, R77 and R82 control the amount of differentialgain slope correction each circuit will provide.Potentiometers R69, R74, R79 and R84 controlthe voltage level, with respect to the luminance level,at which the differential gain correction will occur.To reduce the differential gain correction, thepotentiometers should adjusted CCW.Trimmer capacitor C9 adjusts the total chromagain curve to increase or decrease the overall chromagain. Adjustments should be made while watchingthe demodulated transmitter output on the differentialgain display of a vectorscope.There are four separate independent differentialphase correction circuits. The circuits associated withdiodes CR4 and CR5 will provide a positivedifferential phase correction while those associatedwith diodes CR6 and CR7 will provide a negativedifferential phase correction. Potentiometers R47,R52, R57 and R62 control the amount of differentialphase slope correction each circuit will provide.Potentiometers R49, R54, R59 and R64 controlthe voltage level, with respect to the luminance level,at which the differential phase correction will occur.Adjustments should be made while watching thedemodulated transmitter output on the differentialphase display on a vectorscope. To reduce the

TRH1KE_3.doc3.28-Jul-99 15differential phase correction, the potentiometersshould be adjusted CCW.Video gain is adjusted with potentiometer R21.The video gain should be adjusted to produce a 1.0 Vpeak-to-peak composite amplitude at the switchedoutput which should be terminated in 75 ohms.The sync amplitude may be adjusted bypotentiometer R40. This control should be setmaximum CCW when additional sync amplitude isnot required at the transmitter output.The sync separator circuit contains two trimmercapacitors, C2 and C6. Trimmer capacitor C2 inseries with inductor L1, form a chroma trap.Trimmer C2 should be adjusted to eliminate thechroma on the video signal as seen on the emitter ofQ2. Trimmer capacitor C6 in parallel with inductorL2 forms a high impedance network at the burstfrequency to prevent the burst clamp pulse fromdistorting the burst. Trimmer C6 should be adjustedso that the burst is not affected when observing theoutput of the unit. Care should be taken when makingthis adjustment to ensure that the clamp pulse rise andfall times do not cause spikes before and after theburst. Switch S1 on the corrector circuit boardcontrols the bypass function.Aural Corrector AdjustmentsRefer to 21712091.Note that only the potentiometers and switchesare adjusted here. (The trimmer capacitors areadjusted when the board is aligned).The adjustments on this board are independent;they should not affect any other transmitteradjustment. However, it should be noted that part ofwhat this board corrects for is caused by the IFCorrector. Also, a badly misadjusted Aural Correctorboard could cause undesired FM, cross-mod AM, orimproper aural carrier level ratio.The adjustments are done to minimize theamplitude modulation components on the auralcarrier as displayed on a spectrum analyzer. Theanalyzer should be set as follows: resolution bandwidth of 3 kHz, 200 kHz scan. Adjust the correctorto minimize the peak modulation with all programaudio off. It is also possible to look at a demodulatoraudio output in the frequency domain using a lowfrequency capable spectrum analyzer. Crossmodulation will appear as a 15.7 kHz component andmultiple harmonics thereof. They will all go down asthe correction is performed. The lowest component,at 15.7 kHz, is critical and should be minimized.Adjust the AMPLITUDE 1, SHAPE 1 andPHASE 1 controls as one group and AMPLITUDE 2,SHAPE 2 and PHASE 2 controls as a second group.If the POLARITY switch is in center positionthere will be no correction. In general, switching thePOLARITY to one side will reduce the cross modand switching it to the other side will make it worse.In this case, adjust PHASE for lowest cross mod, andthen fine tune AMPLITUDE. If there doesn't seem tobe any change from center to either side, theAMPLITUDE needs to be increased. If both sidePOLARITY positions make the cross mod worse thanthe center, even when a different PHASE setting istried, the AMPLITUDE may have to be reduced.An iterative process is usually required, workingbetween the controls of one group and then thecontrols of the other. While reducing the crossmodulation as evidenced by amplitude modulation onthe aural carrier pay attention to the sync pulse andany ringing on the leading or trailing edges. Aproperly adjusted Aural Corrector will minimizecross modulation as well as sync ringing.IM Corrector AdjustmentRefer to drawing 22310680.The potentiometers and switches are all systemlevel controls. The trimmer capacitors, on the otherhand, are adjusted when the board is aligned andshould not be touched in the system. The drawing22310680 shows the position of, and labels, thesystem level controls. The on/off, amplitude, phaseand polarity controls are grouped into the categoriesStatic, APL, and Master (affecting both Static andAPL components). The terms STatic, PHase, Right,Left are abbreviated to ST, PH, R, L to save space insome cases.In general, each polarity switch (R, L, R ST, LST) has a PHase control (R PH, L PH, R ST PH, LST PH) and an amplitude control (R, L, R ST, L ST)associated with it. When the master polarity switches(R, L) are in center position, the IM correctoroperation is disabled. When the Static polarityswitches (R ST, L ST) are in center-off, the Staticcomponent is disabled. During system adjustment, apolarity test should be done first. When the two “on”positions of a polarity switch are tried, there are threepossible outcomes:1. Little or no change is observed in the IM inany of the three polarity switch positions.2. Both “on” positions make the IM worse thanthe “off” position.3. One “on” makes the IM better than the “off”(the other “on” makes it worse).In case 1 above, the appropriate amplitudecontrol (potentiometers R, L, R ST, L ST) should beturned up (clockwise) and the polarity test repeated.In case 2 above, the appropriate amplitude controlshould be turned down and the polarity test repeated.

TRH1KE_3.doc3.28-Jul-99 16In case 3 above, the appropriate PHase control (RPH, L PH, R ST PH, L ST PH) should be adjusted tonull the IM. A further null should be tried by slightlyadjusting the amplitude control also.When the board has been adjusted before, but aslight “touch-up” is needed, it is recommended thatthe controls in the “Master” section of the drawing22310680 be used.When the board is being adjusted for the firsttime, the recommended procedure involves using avideo source capable of a fixed amount of chroma ona variable APL flat field. This can be done from aTektronix 147A with 4.43 MHz chroma carrier (onback) looped to the auxiliary input on the front, andusing the variable pedestal control on front. ATektronix 1405 sideband can be used if an external+5 dBm fixed frequency is connected into the 1405’sLO input. The frequency is arbitrary but it should bewithin the 2.09 to 3.1 GHz shown on the back of theinstrument. On the 1405, turn off the sync andconnect the video output to a counter. Adjust the1405’s tuning knob to get 4.43 MHz. Then turn thesync back on and connect the video to the transmitter.If these are not available, a Tektronix 140 or 146 canprovide two color segments on an adjustable level flatfield.The adjustment is done by checkingintermodulation products at two APL levels - perhaps10 APL for black and 80 APL for white. At white,adjust the controls in the “Static” section (see22310680) for lowest intermod. At black, adjust thevideo amplitude controls as well as the phases R PH,L PH in the Master section. If the results are notsatisfactory, try a different master amplitude, or adifferent setting of the High/Low range switcheslabeled R1, R2, L1, L2.Static ICPM AdjustmentsRefer to drawing 22310680.Start with the ICPM polarity switch in centerposition. Make sure the modulation level is correct.Set up the ICPM display using the quadrature outputof a synchronous demodulator for horizontal input tothe waveform monitor or scope. Turn on the zerocarrier pulse on the demodulator. Use un-modulatedstairstep video. The dots corresponding to eachinstantaneous modulation level should form a line. Ifthis line, when extrapolated straight, already passesthrough the zero carrier dot then the Static ICPMcircuit does not need to be used. If not then the otherdots can be shifted relative to the zero carrier dot byswitching the ICPM Polarity to one side andmaneuvering the ICPM amplitude and ICPM PHase.Actually on most demodulators you will see apivoting effect due to the demodulator clampingholding either the sync dot or the 0 APL dot(blanking level) in place. When the adjustment iscomplete the zero carrier dot should line up (as muchas possible) with the other dots, especially the nearestones. Also, the modulation level should not changeas the polarity is switched in and out (disregard theeffect from switching).IF Linearity Corrector AdjustmentsRefer to drawing 22709666.The corrector is adjusted to primarily affect lowfrequency linearity performance and sync level but italso will alter the differential gain characteristics ofthe transmitter. It will be necessary to check thedifferential gain characteristics and adjust the VideoCorrector as necessary after making adjustments onthe IF Linearity Corrector.The Corrector has two identical sets ofadjustments called GAIN and THRESHOLD.Normally only R2/GAIN and R4/THRESHOLD areactive and used. The GAIN adjustment matches thesaturation curve in the transmitter output while theTHRESHOLD control sets the level of Correctionthat is added. The Corrector is not gain compensatedand while the transmitter output will be maintained at100% by the RF Converters IF Amplifier AGCcircuits, the amount of system gain over-range willchange and may have to be re-adjusted when theCorrector adjustments are changed.The GAIN and THRESHOLD adjustmentsshould initially be considered near the optimumsetting. Counter clockwise rotation of the controlsminimizes the effect of the corrector. The correctorshould be adjusted while monitoring the transmitteroutput signal low frequency linearity with a waveformmonitor, and in-band intermodulation products with aspectrum analyzer capable of 100kHz resolution at 1MHz/div, using a modulated ramp video format. Abest fit correction setting will maintain 40 IRE unitsof sync, 5% or better low frequency linearity, and atleast 52dB in band intermodulation products.5.4 AMPLIFIER BYPASS OPERATIONIn the event that one of the 650 Watt Amplifiermodules experiences a failure and must be taken outof service, there is a preferred procedure foroperating the transmitter with one amplifier only.1. Begin by removing the AC mains power to thecabinet. Next, remove the disabled amplifierfrom the cabinet. The spring metal tabs on eitherside of the slides are pushed in to unlock theslides and allow the module to be pulledcompletely out.

TRH1KE_3.doc3.28-Jul-99 172. There are seven connections that need to bedisconnected from the module, four coaxial cableconnections and three harness cable connections.3. The circular multi-conductor plug contains thelogic connections to and from the amplifier andmust be bypassed using the mating jackconnector with a single wire in place, that wassupplied with the transmitter. This bypassconnector is keyed and need only be connectedto the cabinet cable end.4. The output of the hybrid combiner that isconnected to the remaining amplifier must be re-cabled to the directly to the output directionalcoupler. Remove the output cable connectionfrom the remaining amplifier combiner andreconnect to the output directional coupler.5. The Intermediate Power Amplifier RF outputsthat connected into the removed 650 WattAmplifier must be terminated into suitable 50ohm loads. Two terminations are supplied withthe transmitter accessory kit. Connect these tothe two outputs of the IPA Chassis that wereconnected to the 650 Watt Amplifier that wasremoved.6. Open the Exciter Drawer to access the RFPOWER adjust potentiometer R84. Adjust thepotentiometer fully counterclockwise. Re-applyAC mains power to the transmitter. Start thetransmitter and allow. Place the EXCITER RFCONTROL switch into the AUTO position.Note that it may take a few seconds for an RFpower indication due to the slow release featureof the RF CUTOFF circuits. Observe theCONTROL LOGIC multimeter "PEAK VISPOWER %" position and adjust the EXCITERPOWER CONTROL to set the RF output powerto 50%. Keep the transmitter at this operatingpower until a repaired 650 Watt AmplifierDrawer is re-installed.5.5 RF TRANSISTOR REPLACEMENTShould it be necessary to replace an RFtransistor, select a soldering iron of proper size andwattage. A too small iron will take too long to heatthe desired area possibly overheating other closelymounted components. An over sized iron may notprovide enough control and again overheatcomponents. The proper sized iron should be 30 to40 watts. 60/40 solder is recommended.1. Carefully remove components located around thetransistor leads. The input trimmer capacitor onthe base leads, must be removed by heating bothsides alternately. Then the air coils must beunsoldered at the collector points only, andslightly bent back for clearance.2. Note the position of the transistor leads. Thecollector lead is the narrower lead whencompared to the base lead. Unsolder the leads byapplying heat and lifting up to the lead with afine screwdriver blade or similar instrument.3. Remove the transistor monitoring screws anddamaged transistor. Clean area beneathtransistor of all thermal compound and makecertain there is no dirt or grit on the mountingsurface. Wick excess solder off of the base andcollector PCB tracks. Using the old transistor asa template, cut new transistor leads to length.4. Use a small amount of clean thermal compoundon the bottom of the new transistor and place onmounting surface.5. It is very important to properly tighten thetransistor flange. The mounting hardware shouldbe lightly and alternately snubbed down to fingertight. Next the hardware can be tightened toapproximately 5 inch pounds in at least twosteps. Do not completely tighten one side to thefinal torque specification without tightening theother side as this may cause a failure of thetransistor die.6. Resolder transistor leads using a minimum ofsolder and replace the base trimmer capacitor byholding in place with a needle nose pliers andalternately heating each side until the existingsolder flows to its leads. Hold the collector coilsdown to the board tracks and heat until solderflows to the coils.5.6 CLEANING AND MAINTENANCESCHEDULEIn order to obtain maximum system reliabilityand maintain optimum performance from theequipment, it is important to establish a systematicpreventative maintenance schedule. A wellconstructed program will aid the operator with propersystem operation. A recommended schedule is listedon the following pages.Daily1. Monitor and record all operating voltages andcurrents at a specified APL.2. Monitor and record output making sure to checkfor excessive reflected power and a 10dB aural tovisual ratio.3. Check Exciter front panel LEDs.4. Check visual modulation level and auraldeviation.

TRH1KE_3.doc3.28-Jul-99 18Weekly1. With power off, thoroughly inspect unit makingsure to check all high current, high powerconnections for tightness. Tighten as required.2. Check/clean the cooling fan input air filter.Check for unusual fan noises.3. Measure and record key video parameters.4. Monitor and record local oscillator frequency.Every 2,000 Hours Of Operation1. With power off, clean, dust, etc. from highcurrent components, assemblies.2. Using a sideband generator, check the tunedresponse of the transmitter.3. Clean or replace air filters for input air to thetransmitter room.4. Check for loose screws, bolts, etc. on allassemblies.5. Monitor all video parameters and spectralresponses for spurious signals.
