III — TRANSMITTER INSTALLATION
To ensure long and reliable trouble free service from the UTX5KW-A transmitter, the following steps
for installation are recommended:
1. MECHANICAL INSTALLATION: The UTX5KW-A was designed to be installed in a building
protected from the weather. The building should have a hard surface oor such as concrete with a
moisture barrier. This barrier could be pressure treated wood sub-ooring which could be anchored to
the concrete and to the transmitter to make the installation earth quake resistant.
Allow a minimum of three feet around the transmitter cabinet for service access. The top of the
transmitter should be clear three feet above to allow the air to exhaust from the transmitter.
Air ow thru the transmitter is approximately 2500 CFM. Provisions for air inlet and exhaust from the
room must allow air ow with minimal obstruction. In the event that the room temperature exceeds 35
degrees Celsius, cooling air must be provided so that the room temperature will not exceed 35 degrees
Celsius under worse case conditions.
Notice: This equipment is HEAVY and must be handled by professional movers with proper equipment.
Any damage caused by the installers is not covered under warranty. Check to ensure that installing crews
have proper insurance coverage.
2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly for safety
and operational reasons. A typical installation may be done as follows:
Use a heavy gauge wire such as #2 AWG strained copper or solid copper buss one (1) inch wide
by 1/8 inch thick for connections. The bonding between the transmitter and the ground rods must be
good quality and protected from corrosion. The ground wires should run over the oor and connected
to the ground rods located outside the building. The wire should not go thru the concrete oor but
over and around it.
3. AC WIRING: A ten-foot cable has been provided with the transmitter to facilitate the connection to
the AC Main power source.
Connections to the AC Main should be made as follows:
RED, BLACK, AND ORANGE are connected to the 208 VAC 3-PHASE terminals
WHITE WIRE is connected to the NEUTRAL terminal
GREEN WIRE is connected to the SAFETY GROUND
NOTICE: All wiring of this type must be done by A QUALIFIED ELECTRICIAN and must conform to
LOCAL and NATIONAL wiring CODES.
Consult with your electrician to ensure that the proper breaker size is selected for the main circuit.
4. ANTENNA CONNECTION: The transmitter is equipped with 1 5/8 EIA Flange connector located at
the top of the rack. Conditions vary from site to site so some engineering may be required to ensure
that the antenna is receiving the correct amount of power to comply with FCC licenses and to ensure
safety from lighting etc.

Page 6
IV — TRANSMITTER TURN ON PROCEDURE
Before applying AC Power to the transmitter for initial turn on and check out, the installation should be approved
by a qualied broadcast engineer. The Turn on procedure that follows is recommended by Pineapple Technology,
Inc. engineering staff:
1. Check transmitter load or antenna for proper installation and connection to the transmitter.
2. Open the transmitter and inspect all cables and wires for lose connections or broken wires in the rack assembly
3. Check for damage to the equipment mounted in the rack.
4. Check all AC breakers and on/off switches to ensure that all are OFF.
5. TURN ON THE MAIN AC BREAKER LOCATED IN THE SUB-PANEL WHERE THE AC POWER CORD
WAS CONNECTED.
6. TURN ON THE MAIN AC BREAKER LOCATED ON THE ACDIS5 POWER DISTRIBUTION PANEL
LOCATED ON THE FRONT OF THE TRANSMITTER. A GREEN LIGHT SHOULD COME ONE
INDICATING POWER IS ON.
7. TURN ON THE AC SWITCH LOCATED ON THE FRONT OF THE ADP500. THE INDICATING LIGHTS
SHOULD BE ON AND READY FOR OPERATION
8. TURN ON THE AUX BREAKER LOCATED ON THE ACDIS5 FRONT PANEL. THE PA FANS AND THE
RACK EXHAUST FANS SHOULD COME ON.
9. TURN ON THE POWER SUPPLY BREAKERS LOCATED ON THE FRONT OF THE ACDIS5. CHECK
THE RR6000 POWER MODULES — NINE (9) EACH — TO SEE IF THE GREEN LIGHTS ARE
INDICATING NORMAL OPERATION.
10. USING THE ADP500 & PAS10 CHECK THE IDLING CURRENTS ON EACH PA TO ENSURE THAT
THE CURRENTS ARE IN THE CORRECT RANGE. TYPICAL RANGE IS 1.5 TO 2.5 AMPS. SEE
ADP500 OPERATING SECTION FOR DETAILS
11. TURN ON THE DRV100 DRIVER AMPLIFIER. THE GREEN LIGHT SHOULD COME ON.
NOTICE: The Modulator/Upconverter has been set at the factory so that the output power indication on the
ADP500 will show 100% or 3 KW p-sync power level. It is important to read the instruction manual supplied
with the modulator to locate key adjustment devices on the front panel. The output level adjustment will be
necessary for the next step in the turn on procedure.
12. Locate the level adjustment on the modulator/upconverter and turn the level down to minimum or CCW.
13. Turn on the power switch located on the modulator rear panel.
14. Apply a video signal (1 volt P-P) to the video input terminal
15. Slowly increase the output level adjustment while watching the RF Output level on the ADP500. When the
output gets up to 50% indicated power stop the adjustments.
16. Using the ADP500 reected power indication check the LOAD reected power. This should be less that
5% reected.
17. Return to the PA current readings on the ADP500 to verify that all the currents are approximately the same.
18. With successful performance thru step 17, the transmitter output power can be increased using the output level
adjustment on the modulator to achieve 100%. The aural power can be added at this time not exceeding 10%
of output p-sync power as indicated on the ADP500.

UTX5KW-A Operating and Service Manual
V — THEORY OF OPERATION
A. INTRODUCTION
The UTX5KW-A transmitter was designed to meet or exceed all FCC applicable specications for TV
Broadcast Equipment. Special attention was given to the selection of sub-assemblies and components to
achieve maximum reliability and minimum down time. The construction of the UTX5KW-A is BASIC
and MODULAR with most components eld replaceable. Special emphasis was placed on “KEEPING
IT SIMPLE” and returning to more traditional transmitter layouts and instrumentation.
This transmitter was designed for Analog (NTSC) transmission with provisions and options available to
convert to digital service when necessary.
Refer to the UTX5KW-A block diagram – gure 1 (page 8) for an overview of the transmitter architecture.
SEE SECTION VI.A (page 14) FOR PARTS LIST
B. ACDIS5 AC DISTRIBUTION
The ACDIS5 is the primary AC power inlet module. The UTX5KW-A transmitter was designed to except
208 to 230 V AC 3-PHASE using a FIVE (5) wire connection. The ve wires are:
• 3 wires for 208-230V AC 3-Phase
• 1 wire for neutral connection
• 1 wire for safety ground connection
CAUTION: Connection to the AC Primary Source must be made using all ve wires listed above. Follow
the wiring instruction given in the AC WIRING SECTION (III. 3.; page 5), If not followed, severe damage
to the transmitter and or electrical shock is possible.
The ACDIS5 performs the following functions:
1. Provides a primary AC power breaker point to shutdown the transmitter.
2. Provides 208 VAC to each of the 2 KW DC power supplies with individual breaker points for added
safety.
3. Provides 110 VAC circuits for Modulator, ADP500, ABS (auxiliary backup power supply), and AUX
Power where needed.
4. Provides 208 VAC to power cooling and exhaust fans.
SEE SECTION VI.B (page 15) FOR SCHEMATIC AND PARTS LIST
C. RR6000 POWER SUPPLY
The UTX5KW-A transmitter is designed with over 18 KW of DC power available to the transmitter. To
achieve this level, the power supply is made up of nine (9) RR6000 power module mounted into three (3)
main frame assemblies which are capable of managing three (3) 2 KW modules each.
The power modules are “HOT PLUGGABLE” and can be removed or installed without turning off the
transmitter.
Each power supply module has OVER VOLTAGE, OVER CURRENT, and OVER TEMPERATURE
protection as well as a fault signal in the event of a failure.

D. ADP500 & PAS10 PERFORMANCE MONITOR
The ADP500 & PAS10 (PERFORMANCE MONITOR) provides the following functions:
1. Monitors FORWARD AND REFLECTED POWER to the antenna and presents it as a percentage of
power rating. The transmitter comes set to 100% P-Sync power based on the ratings of the transmitter
or service requirements.
2. Monitors Aural Power as a percentage of P-Sync rating (5-10% typical)
3. Provides a HIGH ANTENNA VSWR MONITOR In the event of an antenna or coax failure where
the reected power exceeds 25% the transmitter will shutdown. Front panel LED will change from
green to red in case of a fault.
4. Provides current monitoring of all the pallets used in the ten (10) U600LDV-2 power amplier
assemblies. The current levels can be read directly from the multi-meter on the front panel. Individual
pallets are selectable on the ADP500, and the PA assemblies are selected using the PAS10. In normal
operations, a PA FAULT is indicated by going from green to red. RED indicates that the current level
is below 500 ma and a transistor could have failed. To read the actual current, select the appropriate PA
Bank using the PAS10. The ADP500 will now display status of each pallet in that PA. The multi-meter
will read the actual current.
5. A PA INHIBIT switch is provided for failure diagnostic purposes. When activated, this switch allows
the technician to monitor the bias currents for each pallet. These readings should be recorded when
the transmitter is rst installed and used as a reference. This is the best way to trouble shoot possible
transistor problems. When in the PA INHIBIT mode, the RF PWR OFF LED will change from green
to red indicating that the “SHUTDOWN LINE” Is at a TTL 0 state and the output power has been
reduced to near zero.
6. An RF MONITOR port (BNC) is available to connect a spectrum analyzer for monitoring the output
signal.
METER SELECTOR SWITCHES
The PAS10 is used to select the appropriate PA Module ( U600LDV-2) for performance display on the
ADP500. PA designations are PA1 starting from the top row going left to right with PA10 being on the
right side in the fth (5th) row down when viewed from the front of the transmitter.
The Rotor Switch on the ADP500 is the detail selector for the multi-meter. The various positions are
dened as follows:
PA1 THRU PA5 ................................................... Reads PA pallet currents as selected
Typical reading in INHIBIT MODE 1.5 TO 2.2 A
Typical reading with SMTPE BARS — 5-7 A for PA1
thru PA4 Typical reading with SMTPE BARS — 2-3 A
for PA5
PA6 ..................................................................... NO CONNECTION

UTX5KW-A Operating and Service Manual
L. BPU5KW UHF BAND PASS FILTER
This Band Pass lter was designed to meet FCC Certication requirements with minimum loss of RF
Power. The BPU5KW comes tuned and tested to the operating frequency of the transmitter and should
not be adjusted without proper equipment. Replacement lters are available as P/N BPU5KW UHF
(+CHANNEL NUMBER).
M. AUX5 MONITOR PANEL
The auxiliary monitor panel provides analog meter measurements for the primary DC supply. The total
power supply current and voltage are displayed on these meters. These measurements serve as a good
indication of the operations of the transmitter nal power ampliers.
Each power supply has a current monitor output. These outputs are accessible on the AUX5 Front panel.
Each ( PS I SHARE ) test point will indicate a relative amount of current being supplied from the power
supply. This is not a calibrated or accurate measurement that is scaled from the current capability of the
power supply. This is also a second-level diagnostic tool for use by qualied technicians.
In the event of an EMERGENCY, a SHUTDOWN SWITCH located on the AUX5 will shut down the
transmitter and remove all power starting from the MAIN 3-P BREAKER. To turn the transmitter on,
it is necessary to RECYCLE the SHUTDOWN SWITCH before the transmitter MAIN BREAKER can
be turned on.
N. FP-10 FUSE AND SHUNT PANEL
The FP-10 serves as a DC SUMMING POINT for all current coming from the power supplies. After being
summed the current passes through a 500 AMP precision shunt which is used for measuring the total
supply current and voltage being applied to the transmitter power ampliers. At this point, the DC Power
is distributed to each U600LDV-2 amplier assembly thru a series 80 amp fuse.
NOTICE: BEFORE ANY SERVICE WORK IS PERFORMED ON THE FP-10 ALL POWER TO
THE TRANSMITTER MUST BE TURNED OFF FOR SAFETY.

VII — ROUTINE MAINTENANCE
VII — ROUTINE MAINTENANCE
The following KEY MAINTENANCE AND PERFORMANCE CHECKS should be made monthly or more
frequently in some environment where dust is a problem:
TRANSMITTER
• Remove and clean the air lters with a light detergent and DRY COMPLETELY before re-installing. Dirty
lters will cause PA amps to shutdown resulting in a loss of RF power. Spare lter P/N 990199 is available
from Pineapple Technology, Inc.
• Check and record the Voltage and Current meter readings on the ACDIS5 (AC AND DC DISTRIBUTION
UNIT LOCATED NEAR THE POWER SUPPLIES). NOTE: current readings will vary with picture content,
therefore, a standard video waveform such as SMPTE BARS should be used.
• Using the ADP500 & PAS10 — record the bias level settings on each PA Pallet by selecting the appropriate PA
with the selector switch. To make this measurement of BIAS ONLY it is necessary to activate the PA INHIBIT
switch momentarily for each reading.
• Using the ADP500 — check and record the RF Output power level to ensure that it is still reading 100% +/-
10% from the previous settings.
• Using the ADP500 — check and record the VSWR (Reected power) to ensure that it is still reading only a
few percent indicating normal load operations.
• Using the ADP500 — check and record Aural power readings. This is normally set between 5 and 10% of
P-sync. Expect this to vary only a few percent from reading to reading.
• Carefully inspect RF Output coax and coaxial ttings for excessive heating or discoloration.
• Check power supply, shunt, fuse, and PA DC Connections for any signs of over heating or loose hardware.
• Check output combiner and BP lter for any signs of over heating.
FACILITIES
• Clean all air inlet lters and exhaust outlets to ensure that the transmitter is getting clean unobstructed air ow.
• Perform recommended service on air condition systems.
• Rodent traps or baits should be renewed to keep the facilities clear of these pests which can cause damage
to the transmitter.

VIII — ADJUSTMENTS AND TUNING
VIII — ADJUSTMENTS AND TUNING
The UTX5KW-A is basically an FCC Type Certied broadband transmitter with a few frequency selective
sub-assemblies. A list of these sub-assemblies are listed below and followed by general instructions where
applicable:
A. MODULATOR/UPCONVERTER — Instructions for making adjustments to the modulator are
included in the manufacturer’s instruction manual.
B. BPU5KW Band Pass Filter comes adjusted to the channel as purchased. To change frequency would
require a tuning adjustment to the lter. To perform this adjustment it is necessary to use a NETWORK
ANALYZER and a signal generator with necessary I/O Adaptors to connect to the lter. The Technician
performing this adjustment should be skilled in tuning Band Pass Filters. If the target frequency is
outside of the tuning range of the lter, it becomes necessary to purchase a new lter. Replacement
lters and service is available from Pineapple Technology, Inc.
C. U600LDV-2 POWER AMPLIFIER MODULE — The U600LDV-2 has three areas where adjust-
ments may be necessary over time or in the event of a frequency change. These areas are:
1. Bias adjustments: The LDMOS FET devices used in these pallet ampliers are set to 500ma/device
side or a total of 1 amp/device. This adjustment can be made on the bench by rst terminating the
input and output with 50 ohm terminations. Apply 31 volts DC to the PA using a power supply that
can provide a minimum of 15 amps. Note: a cooling fan will be necessary to cool the amplier
during this adjustment.
To adjust the bias’ it is best to turn all the bias adjust resistors CCW or to minimum on the pallet
being adjusted. Using a clamp on AMP Meter connected to the DC Feed terminal located on the DC
ISOLATION AND CURRENT MONITOR BOARD measure the current levels. The rst resistor is
increased to 500ma indicated on the Amp meter. Repeat this adjustment for each additional resistor
for reading of 1.0 A, 1.5 A, and 2.0 A. This will indicate that each device half is set to 500 ma.
This concludes the bias adjustment procedure. This adjustment should be made at any time when
a device has to be replaced. Normal bias ranges from 1.5 amps to 2.3 amps per pallet as indicated
on the ADP500/1000. DO NOT USE THE ADP500/1000 CURRENT READINGS FOR MAKING
BIAS ADJUSTMENTS.
2. PA PALLET RF circuit tuning: These circuits are broadband and xed tuned providing no adjust-
ments. Any tuning at this level is performed by the factory.
3. GAIN & PHASE MATCHING: Each U600LDV-2 comes with a circuit for making Gain and Phase
adjustments. This adjustment is xed tuned for the channel of this transmitter. Adjustment to this
circuit requires the following equipment:
• HP 8508A VECTOR VOLTMETER
• BIRD THRU LINE WATT METER
• SPLITTER
• 2ea DIRECTIONAL COUPLERS
• 2ea 500 watt terminations
• Component selection charts for resistors
• Component selection chart for capacitors
Component selection charts and setup block diagram provided as needed. Recommended tuning should be
within +/- 0.15 dB and +/- 3 degrees as measured on the HP 8508A.
PINEAPPLE TECHNOLOGY, INC.
UTX5KW-A Operating and Service Manual
Page 55
VIII — ADJUSTMENTS AND TUNING
D. PHASE MATCHED CABLES: The cables used to connect the splitter to the PA Amplier inputs and
those provided to connect the PA Ampliers to the combiner are phase matched. If a cable is damaged
and needs to be replaced, additional cables are available from Pineapple Technology, Inc. The customer
may manufacture additional cables, however the same coax type with the same connector types should
be used. The phase matching procedure listed above may be used for adjusting the lengths. Matching
should be within +/- 2 degrees.
E. ADP500/1000 WATT METER: This unit comes calibrated from the factory for the rated power level of
the transmitter. Adjustments are not recommended in the eld.

IX — PROBLEM SOLVING/TROUBLE SHOOTING
IX — PROBLEM SOLVING
The UTX5KW-A is a complex assembly of Digital and Analog circuits and in many cases it is advisable
to contact Pineapple Technology, Inc. for assistance. If it is necessary to perform eld service on the
transmitter, most parts are available from Pineapple Technology, Inc. for next day shipment.
The failure analysis of the transmitter starts off with the following assumptions:
A. The transmitter is connected to an AC Source which is within the specied voltage range and has
ample power to run the transmitter. This would normally be 208-230 V AC 3-phase with a minimum
of 75 Amps available.
B. The antenna has been checked out and veried to have a VSWR of 1.2:1 or better.
C. The room temperature is < 35 degrees Celsius.
D. There are no restrictions on the air ow in or out of the building.
E. The video and aural signals, to the Modulator, comply with stated specications.
CHECKING THE WARNING LIGHTS
MFA1KW: This unit has dual performance indicator lights located above the air inlets. One set of lights
for each PA assembly is located inside the unit.
HS OVER TEMP GREEN NORMAL
RED FAULT
+28 VDC GREEN NORMAL
RED FAULT
FAN SUPPLY GREEN NORMAL
RED FAULT
HS OVER TEMP FAULT could indicate one of the following problems:
a. Room temperature is too high and the heat sinks are over heating
b. High VSWR on PA output port will cause to Dump Load sensor to Fault.
c. Air lters are dirty and need to be cleaned.
d. Exhaust fan failure (located in the top of the rack).
+28 VDC FAULT could indicate a power supply failure. Check the ADP500 & PAS10 for PA voltage and
current readings. The power supply modules will also indicate a loss of power.
PINEAPPLE TECHNOLOGY, INC.
UTX5KW-A Operating and Service Manual
Page 57
IX — PROBLEM SOLVING/TROUBLE SHOOTING
FAN FAULT indications could mean that the PA blower has failed or there has been a loss of AC power
to the fan. There is also a fuse located just inside of the front panel in case there is a locked rotor failure
condition. To locate and check this fuse it is necessary to remove the MFA1KW from the rack so that the
top cover can be removed. The fuse is behind the front panel near the fan.
ADP500: There are a number of fault indicator lights on this unit that can be used for trouble shooting
possible problems with the transmitter.
With normal operating conditions, all the LEDs located on the front panel should be green. Red lights
could indicate a fault in normal operations of the transmitter. Fault indicators are listed below:
a. ANT VSWR HIGH light is RED. This indicated that the antenna reected power exceeds the set point
in the equipment which is normally set to 10%. When this LED is on, the transmitter shutdown line
is pulled down to ZERO and the transmitter RF PWR OFF LED will also light RED indicating that
the transmitter has been shutdown at the driver level. This condition will automatically reset when the
problem is corrected. CHECK THE ANTENNA FOR POSSIBLE FAULTS.
b. RF PWR OFF light is RED. This will occur anytime the “SHUTDOWN LINE” is pulled to ZERO.
This control line is pulled to ZERO with any of the following faults:
1. ANT VSWR HIGH
2. PA INHIBIT SWITCH IN THE INHIBIT MODE
NOTICE: ONLY THE PA INHIBIT SWITCH OR THE ANT VSWR HIGH WILL SHUTDOWN THE
TRANSMITTER DRIVE CAUSING THE RF OUTPUT TO FALL TO NEAR ZERO.
c. PA1 THRU PA5 LEDs RED would indicate that the PA Pallet current level has fallen below the set
point and could indicate a transistor failure. The normal current with the “inhibit” switch activated
is 500 ma.
RR6000 POWER SUPPLY MODULES
The Power Supply module has two warning lights located on the front panel. Normally these lights are
GREEN indicating that the AC Line voltage and the Over Voltage circuits are within their normal range.
Should either go out of range, the lights will turn RED and the power supply module will shutdown. This
will reduce the available power to the RF Stages and could result in lower RF Output Power from the
transmitter. If this happens, turn off the transmitter for about 1 minute and then turn it back on. If this
warning continues, the module should be removed from the rack and returned for service and a spare
module should be installed to maintain normal operations.
NOTICE: The UTX5KW-A transmitter has nine (9) 2 KW power modules. Under normal conditions, this
is enough head room to allow the removal of one power supply module with little or no reduction in output
power. In the event it becomes necessary to remove a module and the RF Output power drops, the RF
Drive level from the modulator can be reduced to a point where the DC Volt meter on the AUX5 reads
31 volts. This is the maximum output level obtainable with one power supply module removed. On
this transmitter that could be a reduction of less than 500 watts in operational output power. This will
keep the station on the air until the new power supply module arrives. DON’T FORGET TO TURN
THE DRIVE LEVEL UP AFTER INSTALLING THE NEW SUPPLY TO RETURN TO 100%
OPERATION.
