System Theory of OperationSUBTASK 34-50-96-870-001-A01A. Introduction(1) The air traffic control radar beacon system (ATCRBS) is a surveillance system inwide use to locate and identify airplanes within an airspace. However, because ofincreasing air traffic, this system is expanding to include additional facilities for airbornecollision avoidance. To gain a good understanding of Mode S transponder operation, itis necessary to understand the operation of the existing air traffic control (ATC) system.(2) If this is your first contact with the ATCRBS and related equipment, this paragraphwill give you an overall description of the present ATCRBS and then expand thatunderstanding into the new Mode S system.SUBTASK 34-50-96-870-002-A01B. Radar Systems(1) Refer to Figure 3/GRAPHIC 34-50-96-99B-070-A01. The ATCRBS consists of aprimary surveillance radar (PSR) and a secondary surveillance radar (SSR). Thelarge rotating radar antenna that can be seen at or near most air terminals is that ofthe PSR. This system uses conventional radar to locate all airplanes within its rangein terms of range and azimuth. It transmits a burst of energy and then measures thetime to an echo. The time thus measured is converted into range (refer to the notebelow for additional information). The direction the antenna is pointing at the time ofecho detection establishes the azimuth to the reflecting target. This target information isdisplayed Figure 3/GRAPHIC 34-50-96-99B-070-A01 on the air traffic controller's PPI(Plan Position Indicator).NOTE: The time is easily converted into range. The mathematical formulafor distance is: D = velocity x time. The propagation velocity of radioenergy is usually expressed as 12.359 μs / radar mile.34-50-96 Page 29May 18/06

ATCRBS Operation(1) ATCRBS Interrogation Modes(a) The SSR system interrogates the airplane transponder for airplane identity andaltitude. The interrogations are in the form of two modes: mode A for airplaneidentity and mode C which is used to request altitude information (refer to the notebelow for additional information).NOTE: In the original definition of ATC modes, two other modes were defined;mode B and mode D. These also differ only in pulse spacing with mode Bpulses spaced 17 μs, and mode D pulses spaced 25 μs. Mode D waswidely used in Great Britain but recently the aviation industryhas settled on mode A for ATCRBS operation and mode C foraltitude reporting. Modes B and D have been largely abandoned.The US Military uses a system similar to ATCRBS. It is known as IFF(Identification - Friend or Foe). As this name implies, it is concernedprimarily with mission security. Three modes are defined; modes 1, 2, and3. Mode 3 is common to the civil mode A with a pulse spacing of 8 μs. Thisallows air traffic control visibility of all airplanes, both civil and military.(b) All pulses are 0.8 μs wide. The interrogations from the ground station are ata frequency of 1030 MHz. The transponder replies at a frequency of 1090MHz. The received signal from the airborne transponder is decoded by theground system and displayed on the ATC radar screen (see Figure 4/GRAPHIC34-50-96-99B-071-A01). The replies produce either a single or double slash targetdisplay on the controller screen. The controller can also elect to display the airplaneidentification number (as selected by the aircrew) and altitude.34-50-96 Page 31May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352Air Traffic Presentation on the ATC RadarscopeFigure 4/GRAPHIC 34-50-96-99B-071-A01(2) SSR System Interrogation Description(a) Refer to Figure 5/GRAPHIC 34-50-96-99B-072-A01 and Figure 6/GRAPHIC34-50-96-99B-073-A01. The SSR uses a rotating directional antenna to transmittwo pulses which are identified as P1 and P3. The spacing of these pulsesdetermines the mode. In mode A the pulses are spaced 8 μs while in mode Cthe pulses are spaced 21 μs. The SSR also uses an omnidirectional antenna totransmit a third pulse designated P2. This pulse is transmitted 2 μs after the P1pulse and provides a reference for side lobe suppression (SLS). The amplitude ofthe P2 pulse is about the same as the peak side lobe of the directional antenna.Ty p i c ally, this is about 18 dB below the peak of the directional (main) beam.(b) Refer to Figure 5/GRAPHIC 34-50-96-99B-072-A01. Notice the two airplanes onthe drawing. Airplane A is shown within the main lobe of the directional antenna.The amplitude of the P1 and P3 pulses will be substantially greater here than theP2 pulse radiated from the omnidirectional antenna. Therefore, the transponder inthis airplane will interpret this interrogation as valid.(c) Airplane B, however, is outside the main lobe and within one of the side lobes.The P1 and P3 pulses detected here will be the result of side lobe radiation.Recall that the P2 pulse is transmitted by an omnidirectional antenna and is about34-50-96 Page 32May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352equal in amplitude to that of the peak side lobe. Therefore, the P2 pulse detectedby airplane B will be at least as great in amplitude as the P1/P3 pulses. Thetransponder in airplane B will detect this relationship in pulses and discard theinterrogation as invalid, because the P2 pulse is not substantially less than theP1/P3 pulses. As a further safeguard against replies to late-arriving echoes tothis invalid interrogation, the transponder suppresses replies to all interrogationsfor an additional 25 to 45 μs. In addition, the receiver is desensitized for receptionof P1/P3 pulses. The rationale here is that if the side lobes are detectable, thenthe main lobe must be much greater.34-50-96 Page 33May 18/06

Mode A provides ident (identification) information, while mode C provides altitudedata. The reply formats are very similar, differing only in pulse spacing (delay).(b) The ATCRBS mode A transponder reply signal is shown in Figure 7/GRAPHIC34-50-96-99B-074-A01. Notice that the signal can consist of from 2 to 16 pulses.The two framing pulses F1 and F2 are always present and spaced 20.3 μs. Anidentification pulse may be transmitted 4.35 μs after the last framing pulse F2. Theintervening pulses, A1 through D4, make up the coded reply. The X pulse is notused. The coded reply consists of twelve pulses; four groupings of three pulseseach. These groupings give four digits of octal data. The digits are formed bythe sum of the pulse (bit) values; 1, 2, or 4, which can produce a digit value from0 through 7. The A group (A1, A2, and A4) makes up the first digit, the B groupmakes up the second digit, etc. (On the figure, a pulse outlined with a solid lineindicates that the pulse is present. A pulse outlined with dashed lines indicates theposition for that pulse when it is present.) The pulse configuration on the figureindicates a reply code 1324. The first digit, 1, is formed by the presence of only theA1 pulse. The second digit, 3, is formed by the presence of B1 and B2 (1 + 2 =3). A digit 7 is formed when all three pulses of the group are present (1 + 2 + 4 =34-50-96 Page 35May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-93527). Therefore, a reply sequence with all pulses present constitutes a code 7777.The X pulse is not defined in ATCRBS replies. This combination of four digits,each ranging from 0 through 7, makes 4096 (212) different codes possible whichexplains the label 4096 code.(c) The ATCRBS mode C transponder reply consists of the same framing pulses F1and F2 but spaced 21 μs. The intervening pulses, A1 through D4 (except for D1),make up the coded reply. The coding scheme is defined by ARINC 572, commonlyreferred to as the Gillham code, and provides encoded altitude data in the range of-1000 to 127 000 feet, to the nearest 100 feet. Recall that in mode A the individualbits assume a binary value which combines into four, three-bit groups, each groupforming an octal digit. In mode C the individual pulses are combined into threegroups. The A, B, and D (except for bit D1) pulses are grouped into two four-bitgroups to encode the altitude to the nearest 500 feet. The C pulses provide the100-feet deviation (above or below) from the 500-feet level. The mode C encodingscheme is described in Figure 8/GRAPHIC 34-50-96-99B-075-A01. Notice that thebit pattern does not follow a conventional binary progression. This scheme wasdesigned to provide a sequence in which only one bit changes at a time as thealtitude increases or decreases.(d) The upper part of the table consists of a matrix of numbers arranged into rowsand columns. These numbers can be referred to as segment numbers. To findthe altitude to the nearest 500 feet, represented by a given bit pattern, you mustfirst find the segment that corresponds to that bit sequence. Multiply the segmentnumber by 500 and subtract 1000 (or subtract 2 from the segment number andthen multiply by 500).(e) The 100-feet altitude is not as easy. To determine the 100-feet level, it is firstnecessary to decide whether the 500-feet segment is odd or even. Knowing that,you add or subtract 0, 100, or 200 feet to or from the 500-feet level depending onthe C bit sequence as shown in the lower portion of the table.Transponder 4096 Reply Code, Signal FormatFigure 7/GRAPHIC 34-50-96-99B-074-A0134-50-96 Page 36May 18/06

ATCRBS with Mode S(1) Introduction(a) Refer to Figure 9/GRAPHIC 34-50-96-99B-076-A01. Mode S substantiallyenhances the capability of the ATCRBS by adding data link and select interrogationfeatures. The data link capability includes air to air information exchange, ground toair (data uplink or Comm A), air to ground (data downlink or Comm B), and multisite(ground station-to-ground station) message protocol. The mode S transponder canalso function as part of an airborne separation assurance (ASA) system wheninterfaced with a Traffic alert and Collision Avoidance System (TCAS).34-50-96 Page 37May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352(2) Mode S Interrogation Modes(a) Eight different formats of interrogation are used in mode S. These eight can besummarized as three basic types. These are shown in Figure 10/GRAPHIC34-50-96-99B-077-A01 and Figure 11/GRAPHIC 34-50-96-99B-078-A01. Table7/Table 34-50-96-99A-038-A01 is a summary of all eight. The three basic typesare as follows:1Universal ATCRBS All CallThis interrogation is in the form of P1, P3, and an 0.8 μs P4 pulse. Thisinterrogation is recognized by all non mode S transponders in the airspace.ATCRBS transponders reply as usual with the 4096 identification codefor mode A interrogations and altitude data for mode C. Mode Stransponders do not react to this interrogation.2Mode S Only All CallThe second type is the same as the previous universal ATCRBS All Callinterrogation except that the P4 pulse is 1.6 μs long. This interrogation isrecognized only by mode S transponders. However, mode S transponders maysuppress replies if in the lockout condition. Mode S transponders in lockoutreply only to the select address interrogation.3Mode S (Select) InterrogationThe third interrogation type is directed to a specific Mode-S equipped airplane.This interrogation is in the form of P1, P2, and P6. The presence of the P2pulse at the normal ATCRBS SLS location effectively suppressesthe non mode S transponder reply.(b) This variety of interrogation capability gives the ground controller the flexibility ofaddressing airplanes of immediate interest, as opposed to processing replies fromevery airplane in the area.(c) All of the Mode-S uplink or interrogation message formats are summarized inTable 7/Table 34-50-96-99A-038-A01. The fields are described in the followingparagraphs. These descriptions mirror Document RTCA/DO 181 with minorchanges to clarify the text.1Address/Parity (AP)The 24 bit AP field contains the parity overlaid on the address. The fieldappears at the end of all transmissions for uplink interrogations and downlinkreplies, except for Downlink Format (DF) number 11.2Acquisition Special (AQ)The 1 bit AQ field designates uplink format (UF) numbers 0 and16 as acquisition transmissions and repeats as received by thetransponder in DF numbers 0 and 16.34-50-96 Page 39May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352Mode S Discrete Addressing, Pulse P6 DefinitionFigure 11/GRAPHIC 34-50-96-99B-078-A01(3) Mode S SSR Radiation Pattern and SLS(a) Refer to Figure 12/GRAPHIC 34-50-96-99B-079-A01. In mode S, theomnidirectional antenna transmits pulse P5 as the SLS reference pulse. The P5pulse occurs within the P6 pulse and is timed 0.4 μs before the first spr. Thus, if theamplitude of P5 is sufficient to blank the first spr of P6, the interrogation is mostlikely from a side lobe and not from the main lobe. In this case the spr is hiddenfrom the transponder and the reply is suppressed.(b) The transmission of mode S interrogation uses a technique known as binarydifferential phase shift keying (DPSK). This technique is illustrated in Figure11/GRAPHIC 34-50-96-99B-078-A01. For greater detail, refer to the informationbelow.(c) The SSR mode S interrogation pulse spacing and identification is different fromearlier ATCRBS. Notice that the rotating beam transmits two different pulsecombinations. For all call interrogations, the transmitted pulses are P1, P3, andP4. In these interrogations the SLS reference pulse P2 is transmitted by theomnidirectional antenna as in conventional ATCRBS. The P1-to-P3 pulse spacing iseither 8 μs (for mode A) or 21 μs (for mode C), also as in ATCRBS. The P4 pulsefollows the P3 pulse by 2 μs and can be either 0.8 μs (the same as P1 and P3) or 1.634-50-96 Page 46May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352μs. The pulse width of P4 determines the all-call objective. A 0.8 μs pulse is only fornon-mode S transponders, while the 1.6 μs pulse is only for mode S transponders.(d) The mode S discrete addressing interrogation takes yet another form. For thisinterrogation the rotating beam antenna transmits pulses P1, P2, and P6. P1 andP2 are 0.8 μs pulses spaced 2 μs between leading edges. P6 is a single pulse thatis either 16.00 or 30.00 μs long. A data technique known as DPSK decodes theinformation transmitted in the P6 pulse. This technique involves the detection of thephase relationship of the signal at certain intervals. These intervals are referred toas chips. Therefore, timing is the critical factor in this decoding process. Each chip isdefined as an unmodulated interval of 0.25 μs and may be in phase or out of phasewith the preceding chip. If it is out of phase, it is recognized as representing a bitvalue of 1. A chip that is in phase with the preceding chip represents a bit value of 0.(e) As shown in Figure 10/GRAPHIC 34-50-96-99B-077-A01, P6 begins 1.5 μs afterthe start of pulse P2. At 1.25 μs after the start of P6, the first phase reversal (pr)occurs. This first pr is identified as the sync phase reversal (spr). This spr mustbe detected in order to enable a reply response. The final chip is followed by a 0.5μs guard interval. This prevents the trailing edge of P6 from interfering with thedemodulation process.(f) The ground mode S interrogator system uses a monopulse processing scheme todetermine the azimuth bearing to the airplane. This scheme requires only a singlereply from an airborne transponder, as opposed to the two replies necessary in theearlier ATCRBS system to establish the azimuth to the airplane. In this scheme, themonopulse system generates two separate patterns; a single (sum) pattern and adual lobe (difference) pattern. The ratio of the energy received by the sum pattern tothe energy received by the difference pattern determines the bearing of the airplanefrom the antenna beam centerline. The address (derived from the reply) andlocation (azimuth and range) of the mode S airplane is entered into a roll-call file.This file can be visualized as a list of the mode S-equipped airplanes within theirassigned airspace. On a later scan, the mode S airplane is discretely addressed.This discrete address contains a command field that is used to desensitize the modeS transponder to further mode S all-call interrogations. This desensitization is calledMode S Lockout. The ATCRBS-only transponders are not affected by this lockouttechnique and mode S transponders continue to reply to ATCRBS interrogations.(g) When a mode S-equipped airplane moves from one assigned airspace into another,the first ground interrogator can communicate with the next interrogator and passairplane information to that second interrogator. This communication link can be viaground lines or radio link. If this method is used, the mode S lockout is not disabledon the affected airplane and the second interrogator will schedule discrete roll-callinterrogations for that airplane as needed. This technique makes it possible toincrease the airplane handling capacity of the ground interrogator.34-50-96 Page 47May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352(h) In regions where mode S interrogators are not connected via ground or radio link,the protocol for the transponder allows it to be in mode S lockout only for thoseinterrogators that have the airplane on the roll-call list. This enables a secondground interrogator to acquire an airplane into its assigned airspace using theall-call technique as previously described.34-50-96 Page 48May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352(4) Mode S Transponder Replies(a) Typically, the ground-based interrogator tracks an airplane throughout its assignedairspace. The mode S transponder equipped airplane responds to mode Sinterrogations with the ATCRBS 4096 code and the mode S reply format. Duringeach scan, the SSR interrogations are in both mode A and mode C. The mode Stransponder reply uses a technique known as pulse position modulation (PPM). Thisis illustrated in Figure 13/GRAPHIC 34-50-96-99B-080-A01. A pulse transmittedin the first half of the interval represents a logic 1, while a pulse transmitted in thesecond half represents a logic 0. In addition to the message data contained withineach reply transmission, the mode S interrogation also contains a 24-bit discreteaddress. This uniquely identifies the reply and provides for a large number ofairplanes, each with its own distinct address. The mode S reply format is describedin the following paragraphs.Mode S, Transponder Reply Code Pulse FormatFigure 13/GRAPHIC 34-50-96-99B-080-A01(5) Mode S Reply Description(a) The reply pulse pattern is shown in Figure 13/GRAPHIC 34-50-96-99B-080-A01.The reply data block is formed by PPM encoding of the reply data. The first pulseoccurs 128 μs after the start of the P4 interrogation pulse. The mode S transponderreply to an ATCRBS interrogation is identical to the reply transmitted by a non modeS transponder (see Figure 7/GRAPHIC 34-50-96-99B-074-A01). However, the replyto a mode S interrogation can assume several different formats as summarizedin Figure 14/GRAPHIC 34-50-96-99B-081-A01. The fields are described in thefollowing paragraphs.1Announced Address (AA)The 24-bit AA field contains the airplane address in the clear (no specialcoding) and is used in DF number 11.2Altitude Code (AC) FieldThe 13 bit AC field contains the altitude code and is used in downlink format34-50-96 Page 50May 18/06

Typical TDR 94/94D ATC/Mode S Transponder Installations(1) Introduction(a) This paragraph gives you an overview of the TDR 94/94D operating environment.For installation detail, refer to the TDR 94/94D ATC/Mode S Transponder,Installation Manual which is contained in the Collins Pro Line II Comm/Nav/PulseSystem Installation Manual, CPN 523-0772719.(b) The TDR 94/94D ATC/Mode S Transponder offers a wide range of installationoptions. First you should recognize the difference between the TDR 94 and theTDR 94D; the TDR 94 is for single antenna installations, while the TDR 94D canoperate with single or dual antenna installations. You are likely to find the TDR 94Din most TCAS installations because dual antennas are required in TCAS.(c) Both transponders can accept control data in CSDB or ARINC 429 format; this isset at installation by means of special external straps and is determined by the typeof control being used.(d) The following paragraphs and accompanying diagrams describe various installationconfigurations. The first diagram, Figure 15/GRAPHIC 34-50-96-99B-082-A01,shows the various strapping options that must be considered for all installations.These strapping options are applicable to all installations even though they arenot shown on the other block diagrams.34-50-96 Page 57May 18/06

This typeof encoder typically supplies altitude data in Gillham code (ARINC 572) format.The encoder data can be supplied to the CTL 92/92A or directly to the TDR 94.However, because the encoder is likely to be located in the radio rack, with or nearthe transponder, most installations will have the encoder connected directly to thetransponder to keep the wire run short.(b) Figure 17/GRAPHIC 34-50-96-99B-084-A01 shows an installation using a CentralAir Data Computer (CADC) for altitude data which is similar to Figure 16/GRAPHIC34-50-96-99B-083-A01. In each of these cases, external strapping is requiredaccording to the type of altitude data being used.(c) An alternate installation configuration is possible using ARINC 429 code selection.In this case, an ARINC 429 source, such as an FMS, would be shown in placeof the CTL 92/92A with appropriate strapping as shown of Figure 15/GRAPHIC34-50-96-99B-082-A01.34-50-96 Page 58May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352(d) In TCAS installations using Gillham code encoders, two independent encodersare required for monitoring redundancy and integrity. In this case, one encoder isconnected to the transponder, while the other supplies data to the CTL-92/92A. Inthe control the altitude data is converted to CSDB data which is supplied to theCTL-92T. The CSDB data is converted here to ARINC 429 and supplied to thetransponder. In the transponder the altitude from the directly-connected encoder iscompared to the ARINC 429 data from the other encoder. If the two altitude sourcesdo no agree within 500 feet, a diagnostic code is generated.TDR-94 ATC/Mode S Transponder, with CTL-92/92A Transponder ControlUnit, Typical Installation DiagramFigure 16/GRAPHIC 34-50-96-99B-083-A0134-50-96 Page 59May 18/06

If the transponder is operatedwith only a single antenna, a special strap is required. The diagram also shows aCADC for altitude data.

Use of Test ProceduresNOTE: Testing is restricted to only authorized Rockwell Collins service centers.(1) Use Table 1001/Table 34-50-96-99A-009-A01, Final Performance (CustomerAcceptance) Test to determine if the TDR-94/94D is operating properly. Use thealignment procedures in Table 1002/Table 34-50-96-99A-010-A01 to calibrate theTDR-94/94D.SUBTASK 34-50-96-700-002-A01B. Final Performance (Customer Acceptance) Test(1) The Final Performance (Customer Acceptance) Test, Table 1001/Table34-50-96-99A-009-A01, is performed with the cover on the unit and provides a relativelyhigh degree of assurance that the TDR-94/94D is properly operating. The finalperformance test is essentially a return-to-service test. The final performance testcan also be used as a customer acceptance or receiving inspection test. After anyrepairs, all final performance test steps must be successfully completed with the coverinstalled before returning a unit to service. The final performance test can also be usedto isolate a fault to a functional area, thus determining which alignment proceduresmay be applicable. Some of the performance criteria have been adjusted to allow forthe tolerances of typical test equipment.SUBTASK 34-50-96-700-003-A01C. Detailed Performance Test(1) The detailed performance test is combined with the final performance test in Table1001/Table 34-50-96-99A-009-A01.34-50-96 Page 1001Jun 20/08

Fault Isolation PhilosophyCAUTION: REFER TO ADVISORIES PARAGRAPH IN THE INTRODUCTION FORESDS HANDLING CAUTION AND COMPONENT WARNING.(1) This section provides the primary information that repair personnel should use to isolatefaults in the TDR 94/94D. All sections of this manual have important data to aid in thetotal repair and understanding of the unit. These sections are referenced, as necessary,to facilitate completion of the repair tasks.(2) Defective avionics equipment will usually fall into one of two categories: failure with aspecific complaint and failures with an unspecified complaints. The function of thissection is to guide fault isolation, first to a specific malfunction, then to the applicablecircuit area. Voltages and waveforms, in addition to the theory of operation help thetechnician to isolate the faulty parts.(3) Fault isolation and troubleshooting are performed using the test equipment listed in theSpecial Tools, Fixtures, Equipment and Consumables section of this manual.SUBTASK 34-50-96-810-002-A01B. Troubleshooting Approach(1) Unspecified Complaint(a) Troubleshooting a unit with an unspecified complaint requires the technician to testthe unit according to the performance test to determine if a fault actually exists. Incases where the unit passes all portions of the test and no fault is discovered, theunit can be returned to the aircraft as good and reinstalled. However, an actual faultmay still persist and all associated equipment and aircraft wiring should be checked.(b) When a unit does fail the performance test, the next objective is to isolate the actualfault or faults, and begin in-depth troubleshooting procedures. Begin by performingthe specific fault isolation procedure(s) in this section.34-50-96 Page 1002May 18/06

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352(2) Specified Complaint(a) Maintenance tags that indicate specific complaints help expedite the troubleshootingprocess. The technician may, in many cases, choose to omit the performance testand proceed directly to the any applicable fault isolation procedure.SUBTASK 34-50-96-810-003-A01C. Troubleshooting Aids(1) Maintenance Aid Diagrams - Maintenance aid diagrams are provided in the Schematicsand Wiring Diagrams section of this manual, facing the schematic diagrams, to aid incomponent location and identification/location of test points.

If not,readjust A7R111 for a reply rate between 90% and 100%.NOTE: If the Minimum Trigger Level (MTL) cannot be establishedwithin the specified limits, or if the MTL does notstay within the specified limits over the operationaltemperature range, the A7R127 (for the Top channel)and/or A7R137 (for the Bottom channel) (CPN705-3543-020) may be added as needed.1.12 Set the MODE-S test set signal strength for -31 dBm. AdjustA7R123 for desired results.Amplitude of the P1 pulse atJ7-31is5.00±0.05volts.1.13 Repeat steps 1.11 and 1.12 as required.1.14 a. Set the MODE-S test set signal strength to -50 dBm. Measureand note the amplitude of the P1 pulse at J7-31.b. Apply the same input signal level to the bottom channel.Measure and note the amplitude of the P1 pulse at J7-33.c. Verify that the two amplitudes are within 0.1 volts of eachother. If this is not the case, reduce the stronger of the twomeasurements by adjusting the appropriate Slope Adjust,A7R123 or A7R133, until the difference is less than 0.1 volts.NOTE: If this readjustment is performed, then the MTLmust be readjusted in accordance with either step1.4 or 1.11, whichever is appropriate for the Top orBottom channel requiring adjustment.____ V_____VVoltagedifferenceshouldbeless than 0.1 volt1.15 Monitor the positive end of A6C59 on the Video Processor board.1.16 Set the MODE-S test set signal strength to -27 dBm.

DPSK trimmercapacitor A7C301 adjustments should be made in verysmall increments or steps. These adjustments are criticalto the performance of the UUT. Capacitor A7C301 shouldonly be adjusted at the board or card level (if possible).16.2 ±0.2 ȝswideatitsbaseAlignment Procedure Cont.Table 1002/Table 34-50-96-99A-010-A0134-50-96 Page 1075Apr 17/07

ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352STEP PROCEDURE DESIRED RESULTS1.17 To align the DPSK Demodulator VCO, interrogatethe bottom channel with MODE-S ONLY ALL-CALLinterrogations having a signal strength of -60 dBm.Vary the interrogation center frequency above 1030 MHz until thereply rate reduces to 90% and note the frequency as the upperfrequency limit.Vary the interrogation center frequency below 1030 MHz and notethe frequency as the lower frequency limit.Adjust A7C306 such that the two limit frequencies are equidistantfrom 1030.00 MHz. Verify that both frequencies are removed from1030 MHz by at least 0.6 MHz. If exact centering of the centerfrequency is difficult to achieve, the adjustment should be madeto slightly favor the higher frequency limit.__________1.18 The IF bandwidth may be adjusted with A7R305. Adjustmentof A7R305 is critical to the performance of the unit and shouldnot be performed at the top-level assembly unless necessary. Ifadjustment of A7R205 is necessary, then the frequency centeringadjustments performed in step 1.17 must be rechecked.1.19 To align the DPSK demodulator VCO, interrogate the top channelwith a Mode-S Only All-Call interrogations having a signal level of-60 dBm and a center frequency of 1030.0 MHz. Monitor A7TP303with the oscilloscope and slowly adjustA7C352 for the cleanestand most square observed signal pulses.NOTE: DPSK adjustments are interactive. Steps 1.17through 1.19 should be rechecked prior to continuingwith the following procedures.1.20 Monitor J7-33. Interrogate the bottom channel with MODE-Aor MODE-C interrogations having a signal level of -67 dBmand measure the video amplitude of P1 observed. Turn off allinterrogations to the UUT.NOTE: Enable the Self-Test function and adjust A7R122 suchthat the observed self-test signal P1 is equal to the videoamplitude previously observed within ±0.2 volts.Alignment Procedure Cont.Table 1002/Table 34-50-96-99A-010-A0134-50-96 Page 1076May 18/06
