3.1 USER INTERFACE AND SOFTWARE SETTINGS
When the equipment is switched on, the display shows the presentation screen, containing the name of the
device and the release number of the firmware.
The mono/stereo choice is made automatically by MIZAR, detecting the presence of the Stereo Coder
Board (OPT023).
At this stage the device restores the last configuration saved of power, frequency and all other parameters.
The other menu can be accessed by pressing the UP and DOWN keys.
All menus show the name of one or two parameter, which can be the reading of a status (e.g. lock/unlock) or
a setting (e.g. Emphasis circuit ON/OFF). In the latter case, the setting may be changed by pressing the RET
in the relevant menu. When the RET key is pressed while in a setting menu, the parameter name label starts
blinking to show that the setting is being edited and not read.
While the label blinks, the user can change the value shown by pressing the UP and DOWN keys. To exit the
edit mode of a setting, and confirm any change made, press the RET key. To leave the edit mode without
confirming any change, press ESC.
Pressing the ESC key while navigating into menu structure, the main menu with the presentation screen is
reached.
Some parameter can be modified only in a protected mode, this possibility will
be highlighted in the menu list. To enter in the protected mode switch on the
MIZAR with both UP and DOWN key pressed. The confirmation of the
protected mode enter will be the display message below and the blinking red
alarm led. This will remember that in protected mode all the alarms and protections will be disabled.
The existing menu, in the order they can be accessed by pressing the UP key, are briefly described below.
This shows the actual level of Forward and Reflected Power. The Forward
Power level can be adjusted.
This shows the actual alarm threshold of Forward and Reflected Power. Both
levels can be adjusted in protected menu.

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.
33
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.

MOTHER BOARD SCH0377AR2
DESCRIPTION
The board contains the stages needed to condition the audio MONO or RIGHT signals and modulate in
frequency a synthesised oscillator. 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 ge-
gree 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 jum-
pers (JP3-4). When they are both enables they give 75us (for the FCC standard). The insertion of the pre-
emphasis 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 suppres-
sion 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 auxi-
liary 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 devia-
tion 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 mo-
dify 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).
40
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.

RF Section
Check the lock of the oscillator on the whole operating range (87 - 108MHz).
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.

STEREO CODER BOARD OPT023
DESCRIPTION
The board contains the stages needed for the conditioning of the Left channel audio signal and for realising the
stereo encoding in compliance with the standard ITU racc. 450. The Right signal is provided through the
connection to the Mother board. 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 ge-
gree 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 jum-
pers (JP1-2). When they are both enables they give 75µs (for the FCC standard). The insertion of the
pre-emphasis is managed from the frontal panel by activating the electronic switch IC3.
3. Low-pass Filter: the use of two filtering stages with elliptical filters LP1 and LP2 assures the adequate suppres-
sion of input signals at frequencies 19k and 38kHz.
4. Peak Detector: before the emphasis circuit, part of the audio signal is sampled to provide the indication of
the LEFT channel deviation on the frontal display. IC4-A serves as buffer for the duplicator and peak de-
tector.
5. Stereo Coder: stereo encoding is realised inside the MPX1 block, providing the MPX signal in output.

DISPLAY BOARD SCH0372AR1
DESCRIPTION
The MIZAR display board contains the HMI (human machine interface) of the equipment composed by a
alphanumeric 2 rows x 16 columns displayand a keys series, a connector for collecting and sending datas
towards the equipment mother-board and its thinking heart made by a Flash microcontroller.
The board is able of reading 8 analogic signals coming from mother-board. These are only bufferized on the
board and therefore their conditioning is made on the mother-board.
The remaining digital input and output signals are conneted directly to the micro, where is necessary some
interverntion speed, or are multiplexed on shift register where the speed is less important.
The board moreover provide the remotability to the equipment by an asyncronous serial, configurable as
RS232 or RS485 simply connecting the output connector to one of the two serial connectors present on the
display board.

30W FM AMPLIFIER MODULE MFF0025BR0
DESCRIPTION
The MFF0025B amplifier module is designed to amplify the FM modulated carriers in the 87-108MHz band,
and can provide an output of 30W CW. 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.

300W FM AMPLIFIER MODULE MFF0031AR0
DESCRIPTION
The Amplifier Module MFF0031A was designed to amplify FM carriers in the 87 - 108MHz band, and is
able to provide an output of 300W CW. Besides it is provided with an RF Monitor output with a level of -
40dBc ±3dB. In order to obtain the desired gain, the amplifier is made up by two gain stages: the pilot stage
uses a MOSFET BLF244, the final stage a MOSFET SD2942. An input adaptation circuit allows to adapt
the module to various driving levels. The adjustment of the output is achieved by controlling the power level of
the input signal. For both stages of the module there is a control terminal allowing to instantaneously disable
the MOSFETs if needed. The output of the module is completed by an 9th order (4 cells) Low-pass Filter to
attenuate the harmonic level of the esable signal, and by two high-directivity directional couplers needed to
sample part of the Forward and Reflected Power for measuring their levels.
