  • Page 11 Chapter 2. BLOCK DESCRIPTION 2.1 Overview Outline Figure 2.1 Simplified block diagram The trigger pulse from the SPU (Processor) Board is delivered to the MODULATOR Board which outputs the signal to oscillate the magnetron, and then radar wave is emitted from the radiator.
  • Page 13 Function of Each Board (Display Unit) Board Name Function 1) Contains a video amplitier circuit. (a) Applies GAIN, STC, FTC and IR to video signal and outputs to the A/D converter. (b) Adjusts video signal input level (EEPOT). (c) Changes STC curve according to the antenna height set on the Radar menu. (d) Echo Stretching 1.
  • Page 14 Board Name Function 1) Outputs encoded data of EBL, VRM and trackball signals. MAIN PNL 2) Includes GAIN, STC, FTC, and BRIL volumes. Board 3) Reads EBL ON/OFF, VRM ON/OFF, FUNC 1/2/3/4, and Range +/- key data. 03P9220 4) Reads PAL/PAR board status. KEY PNL Board 1) Includes key switches.
  • Page 15 Start-up Sequence Radar start-up sequence Process 1. The soft start circuit activates to protect the power ON/OFF relay contacts. 2. The input voltage monitor checks for abnormal voltage. When ship’s mains is abnormal the ON/OFF relay trips off. 3. The inverter comes on and output all line voltages. The LED comes on and the inverter goes off when overcurrent is detected.

  • Page 20: Auto Tuning Function

    Auto Tuning Function The system provides auto tuning mode which eliminates the adjustment of the receiver for maximum echoes. The “Tune Initialization” is required after not only the installation but also the replacement of RF unit, magnetron, MIC, and SPU board, so that the tune control voltages for each pulse are memorized onto the EEPROM.
  • Page 21: Tuning Indication

    Tuning Indication The tuning indicator extends more than 80% of its full length on all ranges at best tuning. The self-test result display reads the tune indicator voltage. Manual Tuning When tuning mode is changed from auto to manual mode, the tuning control voltage (a) found in full search is selected.
  • Page 22 Video Adjustment The video adjustment is carried out through the Tune/video adjustment menu in the installation setup menu. 7KH IROORZLQJ GHVFULEHV WKH RXWOLQH RI WKH DGMXVWPHQW 1) Main Bang suppression Level (MBS L) is set to 0. 2) EEPOT, U14 is set to minimum. (EEPOT initialization with “L” level of U14 #7) 3) EEPOT gets into step-up mode (U14 #2 is H.) to measure output video level at each step.
  • Page 23 Echo averaging (EAV 1/2/3) Remarks on the echo-averaging feature Echo averaging is a useful feature when used properly. If used improperly, however, the result could be disastrous. Objective and principle of echo averaging The main objective of echo averaging is to discriminate targets (flocks of birds, other ships, fishing floats, etc.) hidden in sea clutter, and stably display long range targets (ship, buoy, island, etc.) which alternately appear and disappear on the screen.
  • Page 24 Echo Stretch 1/2 and Enhanced video 1. Echo stretch 1: Enlarges the echo in bearing direction. The same echo appears on the next sweep. 2. Echo stretch 2: Enlarges the echo in range direction. The signal is integrated in the video amplifier.
  • Page 25: Trail Copy

    Trail Copy Trails can be continued even when the range is changed to a next larger or smaller range scale. Note, however, that when the range is changed, no trail generated for targets outside of the previous range. Example 1) Range scale changed from 3 nm to 6 nm The trail starts for targets more than 3 nm.

    Clutter Sweep The memory of target data, of which level is smaller than the preset value, is erased within about one seconds. As a result, PPI-like picture or less time of the afterglow is obtained. The clutter sweep circuit locates after the echo average circuit. Echo average: off Echo average: on Clutter sweep 1...

    4.8 Notice on Replacing Major Parts MAGNETRON NOTE) The magnetron emits a strong magnetic field. For this season, remove a wrist watch before performing the replacement and use a non-magnetic screwdriver to dismount the magnetron. The estimated life of the magnetron is 2000 hours, (including time in stand-by), however actual life depends on usage.
