HIGH VOLTAGE WARNING LETHAL HIGH VOLTAGES ARE PRESENT IN THE TRANSCEIVER 2A current of 100 mA passing through the human body for one second can kill. This can occur at voltages as low as 35 Vac or 50 Vdc. Some equipment in the system uses electrical power that can be lethal. Whenever practical, before carrying out installation, maintenance or repair, personnel involved must: (1)Isolate the equipment from the electrical supply. (2)Make tests to verify that the isolation is complete. (3)Ensure that power cannot be accidentally reconnected. DO NOT OPEN ANY OF THE UNITS WHEN THE RADAR IS OPERATIONAL - UNLESS FULLY QUALIFIED TO DO SO. 3If it is essential to work on the equipment with power connected, work must only be undertaken by qualified personnel who are fully aware of the danger involved and who have taken adequate safety precautions to avoid contact with dangerous voltages. HEALTH HAZARD 4This equipment contains materials which produce toxic fumes when ignited. 5The inhalation of dust and fumes or any contact with lubricants when cleaning the equipment may be temporarily harmful to health, depending on individual allergic reactions. Components which are broken or overheated may release toxic fumes or dust and must be treated with caution. Do not inhale the fumes and ensure that the dust and debris do not enter open cuts or abrasions. It is prudent to regard all damaged components as being potentially toxic, requiring careful handling and appropriate disposal. Page ivIssue 1 CD-0844 CD-0845 RADIATION HAZARD: NON-IONISING AERIAL RADIATION HAZARD: INJURY CAN RESULT FROM EXPOSURE TO THE MAIN BEAM OF A STATIONARY RADAR AERIAL. DO NOT STAND LESS THAN 2m FROM THE CENTRAL FRONT FACE OF THE AERIAL. 6It is accepted in most countries that no significant hazard is presented by radio frequency mean power density levels up to 10mW/cm. RF power levels in excess of this may cause harmful effects, particularly to the eyes. 7Users of cardiac pacemakers should be aware that radio frequency transmissions, can damage some such devices or cause irregularities in their operation. Persons using a pacemaker should ascertain whether their device is likely to be affected before exposing themselves to the risk of malfunction. SAFETY ALOFT AERIAL ROTATION: BEFORE MAINTENANCE TO THE TURNING MECHANISM TAKES PLACE, DISABLE AERIAL ROTATION. 8When working aloft, ensure that it is brought to the attention of someone in authority at deck or at ground level and that suitably placed warning notices are posted warning that work aloft is in progress. Ensure that the means of access aloft is secure and beware of wet or slippery ladder rungs and working areas. 9When working on or near a radar scanner and other moving or r.f. radiating equipment, ensure that it is switched off and that the fuses have been removed and retained. PERSONAL PROTECTION 10Personal protection must be used whenever the possibility of an uncontrolled hazard exists. For example, a suitable face visor, gloves and a body apron should be worn when handling cathode ray tubes, as a precaution against injury in the event of breakage.

CHAPTER 6 TECHNICAL DESCRIPTION INTRODUCTION 1This chapter provides an overview of the Mk VII Downmast Transceiver CTX-A9, and the associated Turning Mechanism, together with functional and technical descriptions for the electronic units. DOWNMAST TRANSCEIVER 2The downmast transceiver is designed for bulkhead mounting inside the vessel. It comprises a sheet metal rear plate which is formed to include the top of the unit. This is braced by two ‘U’ sections which protrude above and below the rear plate to provide the bulkhead fixing points. The main sub-units are bolted to the rear plate (refer to Figure 1). 3The main sub-units are: (1)EMC Filter (2)Power Unit 45-677-124 (3)Electronic Unit consisting of: (a)25 kW FET Modulator CTX-A369/CTX-A345 (b)Tx Microcontroller PCB CTX-A346 (4)Logarithmic Receiver PCB CTX-A356 (5)RF Head CTX-A384 (6)Magnetron (CTX-A309) attached to the RF Head 4Figure 2 shows the interconnections between the units. 5The Electronic Unit has to be removed to gain access to the modulator and pulse transformer. The 25 kW FET Modulator (CTX-A369) consists of a 25 kW Modulator PCB (CTX-A345) mounted on a chassis, together with the high power FETs and a heatsink. 6The EMC Filter is located at the right hand side of the unit and is fitted to the mounting that supports the Electronic Unit. The output terminal 1TB1 is also fitted to this mounting. 7The RF Head is fixed to the top of the framework and is also supported on brackets. 8Two fans are fitted to the Transceiver. One fan (CTX-A379) located at the base of the Electronic Unit provides general purpose cooling for the whole Transceiver. The second fan (45-683-158), fitted to the Electronic Unit heatsink, provides cooling for the modulator components. KH1252 Chapter 6 Issue 2Page 6.3 9A sheet metal wrap-around cover, secured in position by six captive screws, provides access to the front and sides of the unit. Cable entry is at the bottom of the unit. An earth bonding point is situated on the top. POWER SUPPLY (45-677-124) 10The Power Supply is located at the base of the Transceiver and is secured to two mounting brackets by four captive screws. It provides the +27V DC to drive the 300V modulator power supply in the 30 kW Modulator PCB. The +26V or +36V power supplies are not used (required for X band antenna motor only). (1)+27V (2)+15V (3)+10V (Heater Supply) (4)-15V 25 kW FET MODULATOR (CTX-A369/CTX-A345) 11The 25 kW FET Modulator provides the following functions: (1)Drives the S-band 30 kW magnetron. (2)Automatically adjusts the parameters of the magnetron to compensate for the characteristics of different magnetrons, and to allow for change of characteristics due to ageing. 12Full details of this unit are provided in the Unit Information at the end of this chapter. TX MICROCONTROLLER PCB (CTX-A346) 13The main function of the Tx Microcontroller PCB is to interface the Display Unit with the Transceiver. The PCB carries out the following functions: (1)Controls the transmitter via direct parallel connection or Controller Area Network (CAN) bus. (2)Provides control of the FET modulator. (3)Provides modulator trigger pulses of the relevant width and PRF. (4)Provides sync pulses for the receiver and display units. (5)Provides control of the turning motor and modulator cooling fan. (6)Provides the capability of using an external trigger from 300 Hz to 8 kHz, subject to pulse width. The trigger pulse must be positive from 0V. (7)Provides BITE information on the running parameters from the modulator. (8)Provides BITE information on the running parameters of the control board. (9)Controls the pulse width and PRF via a computer serial link. 14Full details of this unit are provided in the Unit Information at the end of this chapter. KH1252 Chapter 6 Page 6.4Issue 2 LOGARITHMIC RECEIVER PCB (CTX-A356) 15The Receiver Assembly (CTX-A364) consists of a Logarithmic Receiver PCB (CTX-A356) mounted on a chassis with a screening cover. The Receiver Assembly is mounted on brackets attached to the main framework and the LNFE. The Logarithmic Receiver PCB provides the following: (1)RF input stages. (2)Logarithmic amplifier with switchable bandwidths. (3)Video detector and amplifier with three independent outputs. (4)Tune indicating and AFC functions. 16Full details of this unit are provided in the Unit Information at the end of this chapter. RF HEAD (CTX-A384) 17The RF Head comprises: (1)Noise Source CAE-A213 (2)Circulator 45-750-0008-001 (3)Diode Limiter 45-646-608 (4)Bandpass Filter 45-750-0009-001 (5)Low Noise Front End CAE-A217, combining and RF amplifier, balanced mixer, electronically tunes local oscillator and IF head amplifier. 18The Magnetron CTX-A309 does not form part of the RF Head, but functionally completes the RF path. High Power (Tx) Signal Path 19Typical pulse conditions for the 30 kW magnetron are: (1)Short pulse: 50 ns at 6 amps (2)Medium pulse: 180 ns at 8.0 amps (3)Long pulse: 800 ns at 8.0 amps (4)Very long pulse: 950 ns at 8.0 amps 20The magnetron output is fed into port 2 of the circulator, and due to the rotational properties of the circulator, emerges at port 3 and out to the rotating joint. 21A small amount of the magnetron energy leaks across the ferrite junction and into the diode limiter. The limiter in turn limits this energy to a safe level for the low noise front end to use as a tune signal. KH1252 Chapter 6 Issue 2Page 6.5 Low Power (Rx) Signal Path 22Signals, which are target returns, are received by the antenna and are fed to port 3 of the circulator, via the rotating joint. The signals emerge at port 1, and are fed to the diode limiter. Normally these signals are of low amplitude, and will not be limited by the diode limiter. The limited signals are passed through an S-band Bandpass Filter and are amplified by the LNFE and mixed at 60MHz, to produce IF for the receiver. KH1252 Chapter 6 Page 6.6Issue 2

Heading line errors are corrected by the Display ‘skew’ setting. General 13Following installation, the heading line may be checked to give maximum bearing accuracy as follows: NOTE: During the Heading Line alignment procedure, the ship must be stationary on a fixed known heading and must have bearing information from the gyro compass available. The ship is to be alongside; less accurate results are obtained if at anchor or at a buoy. Checking the Alignment 14With the vessel stationary, or at anchor, proceed as follows: (1)Check that the array/gearbox alignment markÙis correct. (2)Switch ON the Display and operate in a HEAD UP mode and at a range of 6 miles. (3)Select a stationary target which can be seen by eye and which paints an echo on the screen. (4)Take a compass bearing on the target, and compare this with the bearing of the echo paint on the display. Note the degree and direction of discrepancy. To Correct an Error (Fine Adjustment) 15Any error is present in the Heading Line may be adjusted as follows: (1)Switch the Gearbox Safety Switch to OFF. (2)Switch all supplies to STANDBY. (3)Using a 12 mm spanner, release the six bolts securing the rear cover to the Turning Mechanism and remove the cover. (4)Loosen the two pillars securing the Azimuth/Heading Line PCB. (5)Hold the antenna secure. (6)Note the position of the pointer on the scale, which is marked in two degree steps. (7)Move the pcb assembly the required amount to correct the mis-alignment. NOTE: Moving the PCB to the left moves the video anti-clockwise with respect to the Heading Line. (8)Retighten the two pillars to secure the Azimuth/Heading Line PCB. (9)Refit the outer cover. DO NOT TIGHTEN. (10)Set the Safety Switch to ON. KH1252 Chapter 5 Page 5.6Issue 2 (11)Set the Display to RUN and check that the visual and PPI display bearing of the known target. (12)To make any further adjustment repeat step (7). (13)Secure the rear cover. To Correct an Error (Coarse Adjustment) 16The Heading Line Opto Disc is factory set, however if the fine adjustment does not achieve the required correction, proceed as follows: (1)Perform Paragraph 15, steps (1) to (3). (2)Disconnect the plug to the Heading Line PCB. (3)Remove the Heading Line PCB, ensuring that the opto sensor does not foul against the opto disc. (4)With the array facing forward, check that the leading edge of the heading line disc recess is in line with the array centre line. (5)The heading line disc recess may be corrected by slackening the three M4 retaining bolts holding the disc in place.Do notremove the bolts completely. (6)Manually rotate the disc to the new position required and retighten the bolts. (7)Refit and reconnect the Heading Line PCB by sliding the opto device over the edge of the opto disc. (8)Refit th…
