Therefore, these characteristics must be checked regularly (by means of the Performance Monitor – see Section 21). Connected position receivers must fulfil the standard IEC 61162-1 1) . ARPA target data are directly dependent upon the accuracy and proper functioning of the selected speed sensor and the gyro compass. DANGER: High frequency radiation Persons must definitely avoid being present in the radiation danger zone of the rotating antenna. In the case of work being done on the antenna unit, the antenna switch situated there must be set to 0 and the transceiver must be discon- nected from the ship’s mains. ☞There is no international agreement about the danger posed by high frequency radiation of the kind produced by the radar systems. In most countries, a radiation density exceeding 100 W/m 2 is consid- ered to be dangerous; in some countries, values over 10 W/m 2 are regarded as not being completely safe. 1) IEC 61162-1 largely corresponds to NMEA 0183 Version 2.30 of 1st March 1998. Antenna Type Transceiver A=Up B=Down Radius of the Radiation Danger Zone Radiation Density 100 W/m 2 Radiation Density 10 W/m 2 5 ft X-Band 12.5 kW, Version A1.4 m14 m 25 kW, Version B1.65 m16 m 8 ft X-Band12.5 kW, Version A0.65 m7 m 14 ft S-Band 30 kW, Version A1.3 m13 m 30 kW, Version B0.7 m7.8 m Particular attention must be paid to the notes and warnings refer- ring to possible faults in the radar display, since such faults can impair the detection of targets. RADARPILOT / CHARTRADAR ED 3038 G 232 / 01 (2002-06) Operating Instructions General Safety Precautions b_r1_esh.fm / 21.06.02 4 DANGER: Injury caused by a rotating antenna When the radar system is switched to "ON", it is possible that, instead of the expected antenna, a different one will begin to rotate. Therefore, it must be ensured beforehand that all antennas can rotate freely and that are no persons near the antennas. The units may be opened only by qualified, trained persons. DANGER: Dangerous voltage Even when the equipment is switched off, there can be a dangerous voltage present at exposed contacts in the units. Therefore, before a unit is opened, it must be ensured that the voltage supply to the unit is disconnected from the ship’s mains, and that it remains disconnected. Because of the capacitors contained in the units, there can be a dangerous voltage present in any unit even several minutes (or several hours in the case of monitors) after switching off and disconnection from the power supply. ☞If the units are to be disconnected from the ship’s mains, it must be remembered that each antenna unit, each transceiver electronics unit and each indicator normally has its own supply of power from the ship’s mains. If, for the transfer of signals (e.g. transfer of the heading signal from the compass system), synchro transmitter are used, a dangerous voltage exists in the units until the reference voltage is switched off.

The modulator pcb is delivered in two versions for the 12.5 kW Transceiver (NG 3028 G 203) and for the 25/30 kW Transceiver (NG 3028 G 206). The versions differ only in a few components. The adjustment of the control voltage for the magnetron is divided into the preadjustment by means of Q1 and a fine adjustment by means of Q5. The DC voltage at J1ac32 and J1ac28 is set by Q1 to a value which can be defined on J1a18 by the TCU by means of IMAG1. For this purpose, a clock signal is used which is generated by IC103, amplified by IC302 and transformed by T1 to the source potential of Q1 (the clock signal which is generated by IC103 can be interrupted from the TCU (ENABLE) by means of IC102). By means of CR2, C6 and R7, a gate voltage is generated from this, and the output voltage at TP3 increases, until the output voltage, which has been reduced by a bleeder consisting of R13, R9 and R41, is higher than the value that is set on J1a18. Then the clock signal is interrupted by IC102, and Q1 is blocked by means of IC402. The operating voltage P850V for the transistors Q3, Q4 and Q5 is adjusted by the TCU at J1c6 by Q5 by means of IMAG2 via IC1 and Q6. With the value of P850V which has been reduced by a bleeder consisting of R18, R19 and R21, the voltage P850V is adjusted by IC1. The magnetron is connected to the signals HEATER_MAGN and CATHODE, and to ground. For gener- ating the trigger pulse for the magnetron, a TTL pulse is given on J1a22. IC102 and IC306 control the power MOSFET’s Q2, Q3 and Q4 which generate a negative pulse at the primary of T2. The pulse is transformed by T2 with a ratio of 1:11 and triggers the magnetron. The magnetron current is first led through an integrating circuit consisting of C30 and R51, then decou- pled by IC202 and led to the TCU via J1c1…

MODULATION CHARACTERISTICS (Paragraph 2.987 of the Rules) 1. Magnetron pulse input was measured with a Tektronix TDS- 360 digital storage oscilloscope and Tektronix 6015 X1000 high voltage probe; and recorded on an HP C2106A printer. Oscilloscope display for each pulse width, corresponding to range in nautical miles (nm), are included as Figures 1a through 1g for pulse widths of 70, 150, 300, 500, 900, 900, 900 nanoseconds respectively. 2. Graphs of occupied bandwidth for pulse widths of 70, 150, 300, 500, 900, 900, 900 nanoseconds are included as Figures 2a through 2g respectively. The plots were made with Tektronix 494P spectrum analyzer and HP 7550 plotter coupled via the analyzer's IEEE 488 Port. 3. Plots of PRF measurement using the TEK TDS-360 digital storage oscilloscope for radar range settings of 0.5, 1.5, 3, 6, 12, 24 and 48 nm are included as Figures 3a though 3g respectively. Analysis of the plots demonstrated that 99% of the spectral density is within a 90.2 MHz bandwidth as used in the emission designator. (See Appendix A for analysis technique). 3 MAGNETRON CONTROL PULSE Nominal Pulse Width: 0.070 microseconds (0.5 nm range) Display: 1000 V per vertical division 0.20 microseconds per horizontal division MAGNETRON CONTROL PULSE FCC ID: QO7NG3028X12-5KW FIGURE 1a 4 MAGNETRON CONTROL PULSE Nominal Pulse Width: 0.150 microseconds (1.5 nm range) Display: 1000 V per vertical division 0.2 microseconds per horizontal division MAGNETRON CONTROL PULSE FCC ID: QO7NG3028X12-5KW FIGURE 1b 5 MAGNETRON CONTROL PULSE Nominal Pulse Width: 0.300 microseconds (3 nm range) Display: 1000 V per vertical division 0.115 microseconds per horizontal division MAGNETRON CONTROL PULSE FCC ID: QO7NG3028X12-5KW FIGURE 1c 6 MAGNETRON CONTROL PULSE Nominal Pulse Width: 0.500 microseconds (6 nm range) Display: 1000 V per vertical division 0.2 microseconds per horizontal division MAGNETRON CONTROL PULSE FCC ID: QO7NG3028X12-5KW FIGURE 1d 7 MAGNETRON CONTROL PULSE Nominal Pulse Width: 0.900 microseconds (12 nm range) Display: 1000 V per vertical division 0.5 microseconds per horizontal division MAGNETRON CONTROL PULSE FCC ID: QO7NG3028X12-5KW FIGURE 1e 8 MAGNETRON CONTROL PULSE Nominal Pulse Width: 0.900 microseconds (24 nm range) Display: 1000 V per vertical division 0.5 microseconds per horizontal division MAGNETRON CONTROL PULSE FCC ID: QO7NG3028X12-5KW FIGURE 1f 9 MAGNETRON CONTROL PULSE Nominal Pulse Width: 0.900 microseconds (48 nm range) Display: 1000 V per vertical division 0.5 microseconds per horizontal division MAGNETRON CONTROL PULSE FCC ID: QO7NG3028X12-5KW FIGURE 1g 10 OCCUPIED BANDWIDTH Nominal Pulsewidth: 0.070 microseconds PRF: 2000 Hz Range: 0.5 nm OCCUPIED BANDWIDTH FCC ID: QO7NG3028X12-5KW FIGURE 2a 11 OCCUPIED BANDWIDTH Nominal Pulsewidth: 0.150 microseconds PRF: 2000 Hz Range: 1.5 nm OCCUPIED BANDWIDTH FCC ID: QO7NG3028X12-5KW FIGURE 2b 12 OCCUPIED BANDWIDTH Nominal Pulsewidth: 0.300 microseconds PRF: 1000 Hz Range: 3 nm OCCUPIED BANDWIDTH FCC ID: QO7NG3028X12-5KW FIGURE 2c 13 OCCUPIED BANDWIDTH Nominal Pulsewidth: 0.500 microseconds PRF: 1000 Hz Range 6 nm OCCUPIED BANDWIDTH FCC ID: QO7NG3028X12-5KW FIGURE 2d 14 OCCUPIED BANDWIDTH Nominal Pulsewidth: 900 microseconds PRF: 500 Hz Range: 12 nm OCCUPIED BANDWIDTH FCC ID: QO7NG3028X12-5KW FIGURE 2e 15 OCCUPIED BANDWIDTH Nominal Pulsewidth 900 microseconds PRF: 500 Hz Range 24 nm OCCUPIE…
