The numbers in the first line are the number of occurred alarm and the maximum alarm number before the lock out of the MIZAR (five). To reset the lock out press RET and RET again. When an alarm occurs the menu is automatically changed to this menu. Model 30W EKA This menu is available only in protected mode. It is possible to choose the Model of MIZAR FM Transmitter between 30W and 300W, between EKA, China and OIRT frequency bands. 3.2 AGC IMPLEMENTATION The AGC goal is to maintain stable the output power. Output power in fact can change due to the increase of amplifier temperature. Note that when you change the operating frequency the output power change due to the different gain at different frequency, but this change is not stabilized by this AGC algorithm. The AGC algorithm is based on the acquisition of the optimal output power level, stored when you change MIZAR output power. To keep the power stable the AGC change the power gain of MIZAR. When the goal power is achieved the AGC stops until the power moves up or down. The AGC work is stopped immediately (output power remains blocked to that reached in the moment of the AGC stop) when one of this condition occurs: • one of MIZAR alarms is triggered; • input power level is to low; • AGC has change the MIRA output power too much. 32 3.3 ALARMS AND AUTOMATIC BEHAVIOURS The apparatus signals a working anomaly when any of the following conditions is met: PLL Unlock Forward Power exceed the threshold Reflected Power exceed the threshold Temperature of the Heat Sink exceed the maximum allowed In case of failure of any of these parameters, the apparatus automatically mute the output power and change the menu to the Log menu with the last alarm highlighted. The value of the failed parameter blinks in its menu, in order to highlight the anomalous working condition. 3.4 STATUS LEDs ON (Green) Blinking Lit REMOTE (Yellow) Unlit Lit ALARM (Red) Blinking Lit RF Output Power is growing from 0 to nominal RF Output Power at nominal value Remote disabled Remote enabled Protected mode entered Alarm present 33 Section 4 - Diagram Contents: - APF073A MIZAR30 Cable diagram - APF074A MIZAR300 Cable Diagram - APF073A_APF074A MIZAR Component list - Modules description 35 36 37 Component list APF073A_APF074A - MIZAR Part Name Code Description Qty 02035 02513 02518 02695 02699 02700 02833 02841 02855 05069 05551B 05552B 07522 07524A 07602 07613 07918 07924 07925 07926 08502 CON0306 CON0340S CON0354R2S DET1220 DET1317R0P DET1361R0P E0050 E0060 FUS5A FUS10B MFF0025BR0 MFF0031AR0 PAN0141 PAN0153R0P SCH0372AR1 SCH0377AR2 V0761 V0768 BNC CONNECTOR FOR RG316 CABLE 90 SMB SOCKET cod.

It provides an output radio frequency signal in the II-VHF band, to drive the final amplification stage. The various sections are analysed below: 1. Balanced/Unbalanced Converter: the conversion from balanced to unbalanced and the input interface of the audio signal are realised la electronically by the IC1-A operational circuit. This assures an high gegree of immunity from disturbances and a perfect symmetry in unbalancing. 2. Pre-emphasis: after the level adjustment, there is the active pre-emphasis stage (IC1-B), with amplification to high frequencies. The time constant is chosen between 25 and 50 microseconds by means of two jumpers (JP3-4). When they are both enables they give 75us (for the FCC standard). The insertion of the preemphasis is managed from the frontal panel by activating the electronic switch IC4. 3. Low-pass Filter: the use of two filtering stages with elliptical filters LP1 and LP2 assures the adequate suppression of input signals at frequencies 19k and 38kHz. 4. Additioner: depending on the operating mode selected by the frontal panel (Stereo or Mono) the MONO signal, after the low-pass filter, is sent to the internal stereo coder (as RIGHT signal) or added to the auxiliary inputs (SCA1-2 and MPX) in the stage composed by IC3-A. 5. Peak Detector: at the output of the additioner, part of the signal is sampled for the indication of the deviation on the front panel. IC5-A serves as buffer for the duplicator and peak detector. Aside from the peak detector for the indication of the modulation level, the board also includes a second detector (IC5-B and D4) used to measure the level of the RIGHT signal. 6. Limitation circuit: TR3 and TR4 realise the deviation limitation circuit by cutting the audio signal which exceeds the set voltage threshold on the relevant basis, by means of the resistor network R51-54. 7. Oscillator: a frequency synthesis oscillator with PLL generates the radiofrequency carrier which is modulated in frequency in the same circuit. The reference frequency is generated by a 5.0MHz TCXO with good temperature stability. 8. RF Driver: after the oscillator there is a PIN diode stage (D3) to check the amplitude of the signal and modify the output power. The dynamic is greater than 40dB. The monolith amplifier (IC6) serves as buffer in order to make the load effects on the oscillator circuit irrelevant. Finally, the stage with TR7 amplifies the signal to the adequate levels for driving the power module. A circuit monitoring the power supply of TR7, composed by TR6 and TR8, activates to switch the transistor off in case of alarms (such as PLL unlock or any anomaly detected by the control board). 39 9. Telemetering: the most important analogue signals – forward and reflectesd power, switch on/off, alarms and temperature – are buffered and made available on the J5 socket for connecting remote control systems.

If the synthesised frequency is not correct, try to correct it by means of the capacitive trimmer of the OSC1 reference. Verify the signal-to-noise ration (CCIR) of the oscillator, which should be >73dB on the whole band. Verify the output level by the J9 (RF OUT) connector, higher than 24.5dBm on the whole band. Verify that the final stage is switched off when the PLL of the oscillator unlocks. Modulation Section Disable the emphasis (from the display). Insert the JP1 jumper (so to have an input impedance of 600Ω). Insert the JP2 jumper to enable the limitation circuit. Provide a 400Hz, 2.2Vpp banalced signal to the MONO input. Adjust R1 in order to have an amplitude of 3.2Vpp on TP1 (on which the oscilloscope is connected). Adjust R21 to obtain a deviation of ±75kHz. Adjust R81 to obtain the indication of the nominal deviation on the display. Double the level of the input signal (4.4Vpp) and check that the modulation increase is no more than 1dB. Audio Section With modulation analyser and audio signal on the MONO input at 2.2Vpp, verify the frequency response from 30 to 15kHz without emphasis. Correct any deviation from the nominal range by acting on LP1 and LP2. Insert the JP4 jumper (50µs) and enable the emphasis from the display. Check the frequency response. Insert the JP3 jumper (25+50µs) as well and check again the frequency response. Verify the frequency response of the MPX input from 30 to 100kHz, calibrating R2 for the nominal deviation with 2.2Vpp signal amplitude. Verify the frequency response of the SCA1 and SCA2 inputs from 50k to 100kHz, calibrating R3 and R4 for the nominal deviation (±7.5kHz) with 2.2Vpp signal amplitude. General Verify the remote switch-off function by short-circuiting pin 5 of J5 to ground. 43 SCH0377AR2 COMPONENT LIST Part Name/Number Description Qty.

In order to obtain the desired gain, the amplifier is made up by two gain stages: the pilot stage uses a BLF242 MOSFET, while the final stage uses a BLF245 MOSFET. An input adaptation circuit allows the adaptation of the module to the various driving levels. The output power regulation is made by controlling the power level of the input signal of the module. The final stage of the module also has a control terminal allowing to disable the MOSFET immediately, if needed. The output of the module is completed by a 9th order (4 cell) low-pass filter to attenuate the level of the harmonics of the signal, and by two high-directivity directional couplers needed to sample part of the Forward and Reflected Power in order to measure their levels. The final is provided with the needed circuits (SCH0371B Interface Board) to read the output Forward and Reflected Power, the heatsink temperature and the voltage supplied.
