CHAPTER 1
GENERAL DESCRIPTION
1.0 INTRODUCTION
This manual gives necessary information about XT150 and XT150S exciter. When
referring to the Mono or Stereo Version, it will be duly noted.
1.1 GENERAL DESCRIPTION
The XT150 is housed in a 3U, 19" rack-mouting container comprising a number of
interconnected modules mounted internally on the main chassis, facilitating
removal and substitution.The power output control, audio input level control
and analog meter for the measurement of operating parameters, are all mounted
on the front panel.
The line power, audio input, RF output and telemetry (optional) connectors are
mounted on the rear panel.
1.2
ELECTRICAL DESCRIPTION
The XT150 is an exciter working in the 87.5 to 108 MHz band, programmable in
steps of 10KHz. Its power output is continuously adjustable from 10W to 150W
into a 50 Ohm load.
The XT150 incorporates a stereo coder which guarantees excellent stereo
separation together with low harmonic distortion (only for Stereo version). It
also accepts two SCA signals. A front panel switch allows stereo operation (only
for stereo version) or "mono/mpx" operation which excludes the stereo encoder
and uses the "right" input as the mono input and the "left" input as the wideband
composite input. The specification features low audio distortion and
intermodulation figures (typically 0.03%) and a high signal-to-noise ratio
(typically -80 dB). A voltage selector on the transformer primary allows a variety
of supply voltages to be used.
1.3 METERS AND INDICATORS
The operating parameters of the exciter can be monitored using the analog
multimeter (12 Fig.1A and 8 Fig.1B) situated on the front panel. The parameter
to be measured is selected by the rotary selector (11 Fig.1A and 7 Fig.1B). The
frequency control (10 Fig.1A and 14 FIg.1B) allows frequencies to be selected
in steps of 10KHz. Three red alarm leds indicate VCO unlock (15 Fig.1A and 11
Fig.1B), excess VSWR on the output and the excess of temperature (4 Fig.1A and
8 Fig.1B), and the shutdown condition, programmed by a remote command (10 Fig.1A
and 6 Fig.1B). Three green leds (7 Fig.1A and 3 Fig.1B) indicate the presence
of +12V, +15V and +28V voltages which are used to power the various cards inside
the exciter. A selector (2 Fig.1A) allows selection between Mono/MPX and Stereo
functions and another selector (6 Fig.1A and 2 Fig.1B) is provided to choose
the level of the input signal. Trimmers are provided for adjustment of left and
right channels (5 Fig.1A and 1 Fig.1B) and a switch allows the stereo subcarrier
to benabled or disabled (3 Fig.1A).
1.4 AUTOMATIC FREQUENCY CONTROL
The operating frequency is governed by a thermally-compensated, reference
Pag. 4
XT150 and XT150S Technical and Maintenance Manual
oscillator working within a phase-locked loop (PLL). The XT150 reaches frequency
lock within a maximum of 30 seconds.
1.5 CONTROL CIRCUITS
The control circuits allow automatic control of output power(internal and
external), maintaining the chosen power level across the entire operating band.
Furthermore another circuit protects the final stage against excessive VSWR or
short circuits and excessive temperature. Then, there are other protection
circuits that allow to limit the maximum output power and to protect the equipment
against a power supply's overvoltage.
1.6 R.F. AMPLIFIER
The RF amplifier is a wide-band design and guarantees an adjustable power output
of 10 to 150 watts across the entire band. A low-pass filter enables the TEX150
to be used as a low power transmitter, connected directly to an antenna.

CHAPTER 2
ELECTRICAL DESCRIPTION
2.1 INTRODUCTION
This section describes, in detail, the operating theory behind the
XT150.
To aid understanding, the unit has been subdivided into
blocks, each of
which is fully described below. The block diagram
is shown in Fig.3.
2.2 POWER SUPPLY
This circuit comprises a board, mounted on a heat sink, which is fixed
to the central part of the lower section of the unit (2 Fig.5). The power
supply generates the various stabilized voltages necessary for each of
the various modules that make up the XT150. The transformer has a
selectable input from 110 V to 240 V and two outputs A +18V (6.3A) and
B +32V (10A). This power supply is composed of two main parts: after
having undergone filtering for mains-borne interference, the supply is
transformed into four lower voltages, rectified, smoothed and
stabilized to the following values: +12V, +15V and 10 to 28V variable
to obtain the high efficiency (85-90%). The +15V supplies the encoder
mixer, the PLL card, the VCO card, the meter 100 card and the alarm card.
The +12V supplies the input of RF power amplifier driver (BGY33) and
the 10-28V variable supplies the output of RF power amplifier driver
(BGY33) and the final power stage of the same module (two MRF317 or two
SD1480).
The variable voltage of the final stage is controlled by the PWR ADJ
control which determines the R.F. power output of the exciter. The
automatic control of output power guarantees the power level set by the
PWR ADJ control right across the frequency range and independantly of
other variables such as temperature, load variations etc. The system
works by comparing the value set by the PWR ADJ control with the actual
power output of the unit and compensating accordingly. The final stage
driveris composed of two separate parts, the input part is supplied with
+12V voltage, and the output part is supplied by the switching power
supply with 4-12V variable voltage obtained dividing the 1 0 - 2 8 V
variable voltage. A power limiting circuit intervenes in the event
of excess SWR on the output, thus protecting the final stage.
2.3 AUDIO INPUT CARD
This card is situated on the rear panel of the exciter (1 Fig.4 and 3
Fig.5). The card filters all audio signal inputs to the unit, removing
RF interference, before supplying them to the encoder mixer or Mono\MPX
card. The main operating parameters of the exciter are available for
remote monitoring via a telemetry connector.
Pag. 9
XT150 and XT150S Technical and Maintenance Manual
2.4 CODER MIXER (only for Stereo Version)
This card is situated in the lower part of the unit (6 Fig.4).
The card can function either as a stereo encoder or as a simple mixer
for the various audio inputs. The function may be selected by a
control
situated on the front panel. In stereo encoder mode, the 19KHz
pilot tone is derived from a quartz crystal reference oscillator. So
too is the sampling
frequency which allows the L and R signals to be separated from the
multiplexed signal, plus the suppression of the 38KHz frequency. The
level of the left and right signals is set by the corresponding selector
situated on the front panel. The signals are then filtered at 15KHz and
pre-emphasized (50µS CCIR, 75µS FCC) before being sent to the multiplex
circuit. The audio signals from the two SCA inputs are mixed in to provide
the output. In mixer mode (Mono MPX) the stereo encoder is bypassed,
the right input accepts a mono signal and the left input accepts a
multiplex signal upto 100KHz. The SCA inputs remain unchanged. Three
rectifiers allow the peak levels of the two inputs "Left/MPX" and "right/
mono" to be displayed on the analog meter, and provide the audio detector
circuit with the deviation level.
2.5 PLL CARD
The PLL card is situated internally, in the upper part of the unit (6
Fig.5). The circuit includes a reference cristal oscillator (optional
high stability), a logic section that includes the frequncy dividers
and comparator. The reference cristal oscillator generates a 4MHz
frequency that is divided to generate a 1KHz fixed signal. This signal
is compared
to the operating frequency generated by the VCO divided
opportunely on the ground of the frequency setted on the Contraves. An
indicator situated on the front panel signals the "unlocked" condition.
The comparator output (AFC signal) is sent to the varicap diodes situated
on the VCO Card.
2.6 VCO CARD
The VCO card is situated internally, in the upper part of the unit
(4 Fig.4). This module includes an audio input stage at low frequency,
a voltage controlled oscillator at low noise (VCO) and a driver stage.
The audio signal supplied by the encoder mixer is amplified and then
injected into the VCO to provide class F3 modulation. The voltage
controlled oscillator (VCO) generates the signal on the frequency setted
on the Contraves. This signal is amplified to 300 mW level (25dBm) to
drive the final stage and to be sent to PLL circuit situated on the PLL
card. The operating frequency genereted by the VCO is divided down before
Pag. 10
XT150 and XT150S Technical and Maintenance Manual
being compared to a reference frequency, generated by a high stability
oscillator (standard 5ppm). The error voltage is filtered and used to
compensate the VCO frequency and guarantee its stability. A trimmer is
present on this card for adjustment of deviation.
2.7 R.F. POWER AMPLIFIER
The final power stage is mounted on a heat sink to dissapate waste heat
and is enclosed in a totally screened, metal container, fixed to the
upper-middle part of the central section of the unit (1 Fig.5). The RF
signal coming from the Stereo Decoder or Mono\MPX at a power level of
about 300 mW, reaches the driver stage (BGY33) and is amplified to a
level from about 1W to 20 W before being further amplified by the final
stage (two MRF317 or two SD1480) to a level of upto 150 W. The resultant
signal is then filtered by a low-pass filter (2 Fig.5) which removes
any harmonic content.A
directional coupler allows the direct and
reflected power levels to be measured and displayed on the analog
multimeter and also fedback to the power supply for automatic control
of the output power (see Power Supply description). A BNC connector
situated on the rear panel provides a power signal at -40 dB of the
amplifier output power.
2.8 METER CARD
This card is situated centrally on the front panel (5 Fig.4 and 7 Fig.5).
The card receives direct and reflected power signals from the power
supply
which, in turn, come from the final power stage. The Stereo
encoder card
supplies deviation and left and right signal levels.
These signal levels are then displayed on the analog meter according to
the position of the rotary selector situated on the front panel.
2.9 CONTRAVES
CARD
This card is fixed to the left-hand side of the front panel (5 Fig.5).
The operating frequency selected by the frequency control is represented
by a signal which is supplied to the frequency dividers that form part
of the PLL circuits found on the PLL card.
2.10 ALARMS CARD
This card is fixed in the lower part of the unit (7 Fig.4). This circuit
allows to adjust, through 7 trimmers, the threeshold of the external
and internal output level, internal and external VSWR level, temperature
and to preset the maximum value of the output power. In case of fault
there isn't an automatic reset, because the transmitter provides to
decrease the output power to continue the transmission without
stops,even if at minimum power.
Pag. 11
XT150 and XT150S Technical and Maintenance Manual
2.11 MONO\MPX CODER CARD (Mono
Version)
This card is fixed in the lower part of the unit. The Mono\MPX card is
an Audio Mixer at four inputs, two balanced (Mono and MPX) and two
unbalanced (SCA1 and SCA2). Mono and MPX input level can be setted
through
relative switches placed on front panel, on 5 fixed positions
and on a variable position from -12dBm to +9dBm (pre-setted at 0dBm).
It's possible to set the pre-enphasis value at 50µS, 75µS or linear.
Then, it's possible to insert or remove a low pass filter at 15KHz.
2.12 CLIPPER CARD (Optional)
This card is fixed with a sandwich structure on the coder card and is
accesible from lower part of the equipment. Its function is that
to limit drastically any audio signal that exceeds a prefixed
threshold. Therefore, it's used to avoid any type of over-modulation
as to maximum peak permitted of ± 75KHz. With an exceeding signal,
immediately too, of 6 dB the nominal
level for a deviation of ± 75KHz, this card allows to contain deviation
increasing within 1dB.

INSTALLATION PROCEDURES
3.1 INTRODUCTION
This chapter contains the information required for installation of the
TEX150 exciter and for preliminary checks.
3.2 UNPACKING
Remove the unit from its packaging and before any other operation, check
for any damage that the unit may have suffered in transit and that all
front and rear panel controls are functioning.
3.3 INSTALLATION
1)Check that the line voltage selector is correctly set for the local
supply. If not, remove the cover on which the voltages are printed
and rotate it until the required value corresponds to the arrow,
and reinsert it. Check also that the fuse (1 Fig.2) mounted inside the
cover is present and in order.
The current capacity of the fuse are as follows:
220-240 V
6.3 A
100-120 V
12 A
2)Now ensure that the PWR ADJ control (9 Fig.1A or 5 Fig.1B) is rotated
fully anti-clockwise, using a small screwdriver. N.B. The control is
a ten-turn potentiometer so care should be taken to verify the minimum
position.
Units are usually shipped with this control already at minimum.
WARNING: When the unit is switched on with the control at its minimum
position, power output is about 10W.
3)Connect a dummy load with a power rating of at least 150 W continuous
to the RF output, situated on the rear panel of the unit. It is advisable
to connect a bypass wattmeter in series with this load in order to verify
the accuracy of the unit's own internal wattmeter (see SETUP 1).

on the rear panel so that the switch is able to short the central
conductor to its screen. Leave the switch in the short-circuit position.
5)Switch the unit's ON/OFF switch (13 Fig.1A or 9 Fig.1B) to the OFF
position.
6) Connect line power to the unit via the VDE socket (2 Fig.2).
Note: It's essential that the unit be properly earthed to ensure both
the safety of the operator as well as the correct functioning of the
equipment.
7)Switch the power On switch (13 Fig.1A or 9 Fig.1B) to the ON position
and check that the three green internal voltage led (7 Fig.1A or 3 Fig.1B)
and the red UNLOCK led (15 Fig.1A or 11 Fig.1B) are all on. Select the
desired operating frequency using the corresponding selector. The red
UNLOCK led should switch off within 30 seconds, indicating that the
oscillator has locked onto the operating
frequency. The frequency selector comprises five figures of which the three to the left of the
decimal point represent (from left to right) hundreds of MHz, tens of
MHz and MHz. The two figures to the right of the decimal point represent (from left to right) hundreds of KHz and tens of KHz.
Eg:
Eg:
098.45 =
ninety eight megahertz and four hundred and fifty
Kilohertz.
103.94 = one hundred and three Megahertz and nine hundred and forty
Kilohertz.
Furthermore, if a frequency is selected beyond the two limits of the
87.5-108 MHz band, the amplifier will continue to work even through the
displayed frequency no longer corresponds to the operating frequency
of the unit.
Note: Transmitting outside the legal band (87.5-108 MHz) is an offence
and may lead to prosecution.
8)After having verified that the UNLOCK led is switched off and that
the unit is therefore locked to the selected operating frequency, switch
the switch connected to the REMOTE connector so as to remove the short
circuit between the central conductor and ground. The RF output is now
enabled and should correspond to a power level of about 10W. To check
this reading, select FWD on the meter selector and read the power from
the 200 W FSD scale.
9)Using a small screwdriver, rotate the PWR ADJ control clockwise; the
power output should increase progressively to a maximum of 100W.
Check the value with the bypass wattmeter which should be within ±10%.
Pag. 25
XT150 and XT150S Technical and Maintenance Manual
10)With the power output at 150W, select a new operating frequency well
away from the current value. Eg: 107 MHz: the UNLOCK led should switch
on and the power output should fall to zero at the same time. Only when
the UNLOCK led switches off (unit locked to new frequency) should the
power output
resume its previous level.
11) Automatic power control check
It is advisable to start this procedure with the operating frequency
set to 87.50 MHz. When locked to this frequency, the PWR ADJ control
should be adjusted for an output power of 50 W. Now, with no further
adjustment of the PWR ADJ control, change the operating frequency in
steps of 4-5 MHz, ensuring that the output power remains constant at
50 W.
12) SWR alarm check
For this test, adjust the PWR ADJ control for a power output of 10W.
Disconnect the output load and check that the S.W.R. led switches on.
Now adjust the PWR ADJ control to check that the unit switches on again
at a reflected power level of about 20 W. Turn the PWR ADJ control for
maximum power and check that the reflected power does not exceed 50 W.
Re-connect the output load and check that REF falls to zero, the SWR
led switches off and that PWR FWD jumps to 150 W.
13) Now short circuit the central conductor of the REMOTE input to ground
and the output power should drop instantly to zero. Removing the short
should cause the power output to return, gradually, to its previous
level.
14) Deviation reading check
The maximum input sensitivity is determined by the position of the INPUT
LEVEL control. In the -12/+9 position, the sensitivity will
d e pend on the L/mpx and R/mono controls. Put the selector in the DEV
position. Connect a low-distortion audio generator to the LEFT and RIGHT
inputs. Inject a 400 Hz tone at a level of 0dBm (775mVRMS= 2.2Vpp).Put the
INPUT LEVEL control in the 0dBm position. Select stereo mode (the
corresponding led will switch on). Enable the PILOT using the relevant
switch (the green led will switch on). With the selector in the R/MONO
position, check that the reading is 0b, measured on the +3dB FSD scale.
Repeat the operation for the L/MPX. Check that the deviation reading
is
100%.

MAX) of 75 KHz for frequency modulated, radiophonic transmissions.
Exceeding this limit will only result in the degradation of signal
quality.
In the case of mono transmissions, the stereo input is available for
frequencies between 15 KHz and 100 KHz (i.e. subcarriers for SCA,
RDS etc.).
