1.1 Outline
The antenna unit uses a Log IF amplifier. The scanner unit is the same as that of FR-2115
(12KW) and FR-2125 (25kW). The difference between 6 kW and 12 kW sets is the use of
different type of the magnetron, and different setting of magnetron current.
The features are;
6 pulselengths enabling echo size on the screen to be similar in all ranges.
Flash ROM enabling program update to use a PC.
Non-interlace, high-resolution display (1024 768 dots).
Improved short-range performance using shorter pulselength and higher repetition rate than
before.
The table below shows the major specifications of each model.

2.1 Overview
Outline
Figure 2.1 Simplified block diagram
TX
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.
RX
The 9.4 GHz echo signal received by the antenna is converted to 60 MHz signal by the MIC,
amplified by IF Amplifier, and fed to the SPU (Processor) Board as a video signal. It is digitally
processed and then displayed on the CRT. The SPU Board contains a video amplifier.
Auto Plotter (optional)
The following signals are applied from the SPU board to the ARP-10/17 Board: Heading,
Bearing pulse, Video, Trigger, Bearing in AD format, and Ship’s speed (contact closure or
NMEA 0183). Target acquision and tracking are performed on the ARP Board. Target data,
target position, CPA, TCPA, Speed, and Course, are displayed on the screen.
Plotter (optional)
Data such as latitude and longitude in NMEA format is delivered from the SPU Board to the RP
Board. Plotter data generated on the RP Board is output to the SPU Board and processed to
display them on the screen. The plotter menu is generated on the SPU Board.

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.
4. ROM, RAM, I/O port, custom IC, AGDC and VRAM are
initialized.
5. The system is initialized using EEPROM and DIP switch
data.
6. The timer starts counting down from 3 minutes (time
remaining for warm-up of magnetron).
7. Checks for the absence/presence of a gyro signal.
8. Checks for the absence/presence of the ARP and RP
Boards.
9. The SPU Board starts operating.
Note) When H-sync signal is not applied to the CRT unit,
no HV is generated, resulting in nothing on the screen.
10. The bearing scale, countdown indication, etc. appear.
11. EEPOT memorizes the preset value.
12. The screen is degaussed automatically.
3-minute warm-up can be skipped by pressing [ENTER]
several times while pressing and holding down [HL OFF].
(Do not release this information to user.)
13. Three-minute warm-up ends.
14. The radar goes into stand-by.
15. Checks for presence of BP (Bearing Pulse) signal.
16. The tuning circuit goes into “short search mode.”
17. When the range is changed, the tuning circuit goes into
“short search mode.”
18. Panel settings are written onto the EPROM.
19. Time data are written onto the EPROM.

Video Signal Flow
The video signal from the RF Unit is applied to J2 of the SPU Board.
The video level is adjusted through the menu so that the main bang level is about 2.2Vpp at the output of EEPOT, U92, #5.
The video signal from an external rader can be connected to J458.
The video level adjustment for the external rader must also be made through the menu.
The ARP video which inputs to the ARP Board is GAIN-, STC-, and A/C SEA adjusted.
2-10
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. The figure below illustrates how the tune
initialization takes place. First, full search is performed using a long pulse to find the tuning
point (a). Next, short search is performed using all pulses to find tuning points (b). After the
initialization, the pulselength used before the tune initialization is selected.
Full search: Varying tune control voltage (TUNE CONT) from about 5 V to 32 V, the
maximum tune indicator voltage is found and that tune control voltage (a) is
memorized.
Short search:The tune control voltage changes between the tune voltage (a) plus and minus
2.5 V for fine tuning.
When the radar is set from ST-BY to TX, short search is made twice. When pulselength is
changed, short search is made once.
