Instruction Manual, Rev. 2 2
Assembly Designators
UBS-Axcera has assigned assembly numbers, Ax designations such as A1, where
x=1,2,3…etc, to all assemblies, modules, and boards in the system. These designations
are referenced in the text of this manual and shown on the block diagram and
interconnect drawings provided in Appendix A.
The cables that connect between the boards within a drawer or assembly and that
connect between the drawers, racks and cabinets are labeled using markers. Figure 1 is
an example of a marked cable. There may be as few as two or as many as four Markers
on any one cable. These markers are read starting farthest from the connector. If there
are four Markers, the marker farthest from the connector is the system number such as
system 1 or translator 2. The next or the farthest Marker is the rack or cabinet “A”
number on an interconnect cable or the board “A” number when the cable is within a
drawer. The next number on an interconnect cable is the Drawer location or Board “A”
number. The marker closest to the connector is the jack or connector “J” number on an
interconnect cable or the jack or connector “J” number on the board when the cable is
within a drawer.

EMERGENCY FIRST AID INSTRUCTIONS
Personnel engaged in the installation, operation, or maintenance of this equipment are
urged to become familiar with the following rules both in theory and practice. It is the
duty of all operating personnel to be prepared to give adequate Emergency First Aid and
thereby prevent avoidable loss of life.
RESCUE BREATHING
1. Find out if the person is
breathing.
You must find out if the
person has stopped breathing.
If you think he is not
breathing, place him flat on
his back. Put your ear close to
his mouth and look at his
chest. If he is breathing you
can feel the air on your
cheek. You can see his chest
move up and down. If you do
not feel the air or see the
chest move, he is not
breathing.
2. If he is not breathing,
open the airway by tilting his
head backwards.
Lift up his neck with one
hand and push down on his
forehead with the other. This
opens the airway. Sometimes
doing this will let the person
breathe again by himself.
3. If he is still not breathing,
begin rescue breathing.
-Keep his head tilted
backward. Pinch nose shut.
-Put your mouth tightly over
his mouth.
-Blow into his mouth once
every five seconds
-DO NOT STOP rescue
breathing until help arrives.
LOOSEN CLOTHING - KEEP
WARM
Do this when the victim is
breathing by himself or help
is available. Keep him as
quiet as possible and from
becoming chilled. Otherwise
treat him for shock.
BURNS
SKIN REDDENED: Apply ice cold water to
burned area to prevent burn from going
deeper into skin tissue. Cover area with a
clean sheet or cloth to keep away air. Consult
a physician.
SKIN BLISTERED OR FLESH CHARRED:
Apply ice cold water to burned area to
prevent burn from going deeper into skin
tissue.
Cover area with clean sheet or cloth to keep
away air. Treat victim for shock and take to
hospital.
EXTENSIVE BURN - SKIN BROKEN: Cover
area with clean sheet or cloth to keep away
air. Treat victim for shock and take to
hospital.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD System Description
ATSC Transmitter/Regenerative Translator
Instruction Manual, Rev. 2 14
System Description
Product Architecture
The Innovator CX Series Systems can be configured as DTV Transmitters (i.e CU3TD) or
Regenerative Translators (i.e CU3RD). The DTV Transmitter (TD) takes an ASI input
and converts it to an On-Channel DTV RF output signal. The Regenerative Translator
(RD) accepts an On-Channel RF signal (-79 to –8 dBm) and converts it to an On-Channel
DTV RF output signal. If an optional preamp is present in the system, it is connected to
the output of the receive antenna and amplifies the weak signal approximately 20 dB.
In single drawer systems (CU0TD/RD-1 through CU0TD/RD-5), the CX drawer is
configured as a transmitter/repeater with an output power level of 5, 30, 50, 100 or 150
Watts ATSC. In multi drawer systems, the CX drawer is configured as an exciter/driver
used to drive additional power amplifier drawers; a single amplifier drawer can operate
at 250, 400 or 750 Watts ATSC; two amplifier drawers can operate at 1400 Watts ATSC;
three amplifier drawers can operate at 2100 Watts ATSC; and four amplifier drawers can
operate at 2500 Watts ATSC.
The Innovator CX Series system provides Adaptive Linear and Non-linear correction
capability for the transmission path as well as internal test sources that are used during
initial system installation. If your system contains the Optional Internal GPS Kit, the
output of the GPS Antenna connects to the J5 TNC connector on the rear panel of the CX
drawer. This kit supplies 10 MHz and 1 PPS references for use in the CX drawer.
CX Drawers
The CX drawer contains the (A12) 8VSB ATSC Digital Modulator (1316294), the (A15)
Downconverter (1316715) and the (A16) Capture Board (1316716). The drawer also
contains the (A6) the Amplifier Assembly, (A7) Output Detector Board (1312207), (A8)
the Innovator CX Control Board (1312543), (A10) the +28V/+32V/+42V/+48VDC Power
Supply and (A9) the +5V, ±12V Power Supply. To make the system a regenerative
translator, the RD kit (1310182) supplies the (A1) 8 VSB Demodulator Board (1308275)
for the drawer.
The type of (A6) Amplifier Assembly used in the drawer changes as the output power of
the system changes. The Amplifier Assembly (1316313) is used in CU0TD/RD-1
systems, the Amplifier Assembly (1312566) is used in CU0TD/RD-2 systems, the
Amplifier Assembly (1316636) is used in the CU0TD/RD-3 systems and the Amplifier
Assembly (1316035) is used in CU0TD/RD-4 and CU0TD/RD-5 systems.
The (A10) Power Supply Assembly also changes as the output power of the system
changes. A +48V/300W Power Supply is used in CU0TD/RD-1 systems, a +28V/300W
Power Supply is used in CU0TD/RD-2 Systems, a +48V/1100W Power Supply is used in
CU0TD/RD-3 systems and a +48V/1100W Power Supply is used in CU0TD/RD-4 and
CU0TD/RD-5 systems.
When configured as an ATSC Transmitter (TD), the ASI “A” input at (J1) connects
directly to the input jack (J30 or ASI IN1), and the ASI “B” input at (J2) connects
directly to the input jack (J31 or ASI IN2), on the (A12) 8VSB Modulator Board.
The 8VSB Modulator Board automatically selects the ASI “A” or “B” input depending on
which input is present.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD System Description
ATSC Transmitter/Regenerative Translator
Instruction Manual, Rev. 2 15
When configured to operate as a Regenerative Translator (RD), the DTV ON Channel RF
Input at (J1 or J5), (-8 to -79 dBm) connects to the Tuner Input Jack on (A1) the 8 VSB
Demodulator Board (1308275) supplied with the (RD) kit. The 8 VSB Demodulator
Board converts the DTV input to a SMPTE-310 output at (J13), which is connected to the
input jack on the (A12) 8VSB Modulator Board. The output of the 8 VSB modulator
board at the RF output jack X-502 connects to J1 on the (A6) amplifier assembly.
The 8VSB Modulator Board converts the ASI or SMPTE-310M input to a digital RF TV
channel frequency in the range of 470-860 MHz.
The RF on channel signal is fed to J1 on the amplifier assembly that connects to the ALC
Board, Innovator CX Series (1315006), which is used to control the drive power to the
RF amplifier chain in the CU0TD/RD-1, CU0TD/RD-2, CU0TD/RD-3, CU0TD/RD-4 and
CU0TD/RD-5 Transmitter/Translators.
In a CU0TD/RD-1 system, the RF is connected to the (A6) Amplifier Assembly (1316313)
that is made up of (A6-A1) the 1W UHF Amplifier Board (1310282) and (A6-A2) the
BLF881 Single Stage Amplifier Board (1314882). The assembly has approximately 35
dB of gain. The amplified output at approximately +37 dBm connects to the (A7)
Output Detector Board (1312207) which provides forward (2V=100%) and reflected
(2V=25%) power samples to the CU Control Board (1312543) for metering and
monitoring purposes.
In a CU0TD/RD-2 system, the RF is connected to the (A6) Amplifier Assembly (1312566)
that is made up of (A6-A1) the 2 Stage UHF Amplifier Board (1308784) and (A6-A2) the
RF Module Pallet w/Philips transistors (1300116). The assembly has approximately 36
dB of gain. The amplified output at approximately +38 dBm connects to the (A7)
Output Detector Board (1312207) which provides forward (2V=100%) and reflected
(2V=25%) power samples to the CU Control Board (1312543) for metering and
monitoring purposes.
In a CU0TD/RD-3 system, the RF is connected to the (A6) Amplifier Assembly (1316636)
that is made up of (A6-A1) 1W UHF Amplifier Module (1310282), the (A6-A2) single
Stage UHF Amplifier Board (1314882) and (A6-A3) the RF Module Pallet w/Philips
transistors (1316084). The amplified output connects to the (A7) Output Detector Board
(1312207) which provides forward (2V=100%) and reflected (2V=25%) power samples
to the CU Control Board (1312543) for metering and monitoring purposes.
An output power sample is also supplied to the front panel sample jack J15, which is a
50 Ohm BNC type. The typical sample value in a CU0TD/RD-3 is approximately 60dB
down from the output power level of the drawer.
The RF output is cabled to J9 the “N” connector RF output jack on the rear panel of the
drawer. In CU0TD/RD-1, CU0TD/RD-2, CU0TD/RD-3, CU0TD/RD-4 and CU0TD/RD-5
systems the output connects to a digital mask filter, low pass filter and then the antenna
for your system. In CU1TD/RD-1, CU1TD/RD-2, and CU1TD/RD-3 systems, the RF
output, from the driver drawer, is connected to J1 on the rear panel of the amplifier
drawer. The RF is cabled to J1 on the Amplifier Heatsink Assembly in the amplifier
drawer. In CU2TD/RD and higher power systems the RF is connected to a splitter and
then to the inputs of the amplifier drawers. In systems with vertically mounted amplifier
drawers, the RF output connects to the High Power Amplifier Assembly RF Input located
on the rear panel of the assembly.

Amplifier Drawers
The CU1TD/RD-1 ATSC system is made up of a CX driver drawer and a 250 Watt ATSC
amplifier drawer. The driver drawer connects to the 250 Watt amplifier drawer and
supplies the needed drive level to produce the 250 Watts output of the system.
The control and operating parameters of the 250 Watt amplifier drawer are displayed on
the LCD Screen on the driver drawer. In the 250 Watt amplifier drawer, the RF input
signal is at J1 on the rear panel of the drawer that is cabled to J1 on the amplifier pallet.
In a standard 250 Watt amplifier drawer, a single +42VDC power supply provides the
operating voltages, through the current metering board, to the amplifier pallet.
In a N+1 250 Watt amplifier drawer, two +42VDC power supplies are diode “ored” and
provide the operating voltages, through the current metering board, to the amplifier
pallet. If one power supply should malfunction, the other power supply will maintain the
necessary voltage to provide the 250 Watts output. The amplified output of the pallet,
which has approximately 15 dB gain, is connected to J2 the 7/16” (1.1cm) Din RF output
jack of the drawer. An output detector board supplies a forward and a reflected power
sample to the amplifier control board for metering and monitoring purposes.
The standard CU1TD/RD-2 ATSC system is made up of a CX driver drawer and a 400
Watt amplifier drawer. The driver drawer output connects to the 400 Watt amplifier
drawer and supplies the needed drive level to produce the 400 Watts output of the
system. The control and operating parameters of the 400 Watt amplifier drawer are
displayed on the LCD Screen on the driver drawer. In the 400 Watt amplifier drawer,
the input RF signal at J1, located on the rear panel of the drawer, is fed to J1 on the
Splitter Board, which supplies two outputs, one to each 888 amplifier pallet. Each
amplifier pallet has approximately 14 dB gain. The amplified outputs of the pallets are
combined in the 2 Way combiner board whose output is at J1. The RF is connected to J2
the 7/16” (1.1cm) Din RF output jack located on the rear panel of the drawer. The 2
way combiner board supplies a forward and a reflected power sample to the amplifier
control board for metering and monitoring purposes. In a 400 Watt amplifier drawer,
the typical sample value at J6, a 50Ω BNC jack located on the front panel of the drawer,
is approximately 65dB down from the output power level of the drawer.
The CU1TD/RD-1 ATSC system w/two dual 888 pallets is made up of a CU0TD/RD-2
drawer and a 500 Watt Amplifier Drawer w/two dual 888 pallets. The CU0TD/RD-1 is
used as a driver that connects to the external Amplifier drawer and supplies the needed
drive level to produce the 500 Watts output of the system. The control and operating
parameters of the 500 Watt Amplifier Drawer are displayed on the LCD Screen on the
CU0TD/RD-1 drawer. In the CU1TD/RD-1, the input RF signal at J1 located on the rear
panel of the drawer, is fed to J1 on the 2 Way Splitter Board which supplies two outputs;
one to each 888A amplifier pallet. Each amplifier pallet has approximately 17 dB gain.
The amplified outputs of the pallets are combined in the 2 Way combiner board whose
output is at J1. The RF is connected to J2 the 7/16” (1.1cm) Din RF output jack located
on the rear panel of the drawer. The 2 way combiner board supplies a forward and a
reflected power sample to the amplifier control board for metering and monitoring
purposes. In a CU500, the typical sample value at J6, a 50Ω BNC jack located on the
front panel of the drawer, is approximately 65dB down from the output power level of
the drawer.

ATSC Transmitter/Regenerative Translator
Instruction Manual, Rev. 2 17
The CU1TD/RD-3, 750 Watt ATSC system is made up of a CX driver drawer and a 750
Watt amplifier drawer. The output of the driver drawer connects to the amplifier drawer
and supplies the needed drive level to produce the 750 Watts output of the system. The
control and operating parameters of the amplifier drawer are displayed on the LCD
Screen on the driver drawer. In the amplifier drawer the input RF signal at J1, located
on the rear panel of the drawer, is fed to J1 on the 4 Way Splitter Board, which supplies
four outputs, one to each 888A amplifier pallet. Each amplifier pallet has approximately
15 dB gain. The amplified outputs of the pallets are combined in the 4 Way combiner
board whose output is at J1.
The RF is connected to J2 the 7/16” (1.1cm) Din RF output jack located on the rear
panel of the drawer. The 4 way combiner board supplies a forward and a reflected
power sample to the amplifier control board for metering and monitoring purposes. The
typical sample value at J6, a 50Ω BNC jack located on the front panel of the drawer, is
approximately 65dB down from the output power level of the drawer.
In higher power systems, multiple amplifier drawers are used along with splitters and
combiners to produce the desired output. A System Metering Board (1312666) provides
forward, reflected, over-temperature and other parameters to the exciter/driver drawer
from the external power amplifier chain.
The CU2TD/RD is made up of a driver drawer, a two way splitter, two amplifier drawers
and a two way combiner with a reject load. The reject load provides isolation protection
of the operating power amplifier if the other amplifier fails. One–half the power of the
operating amplifier drawer connected to the combiner will be dissipated by the reject
load with the other half of the power going to the output filters and the antenna.
The CU3TD/RD is made up of a driver drawer, a three way splitter, three amplifier
drawers and a three way combiner with reject load.
The CU4TD/RD is made up of a driver drawer, a four way splitter, four amplifier drawers
and a four way combiner with reject load. The reject loads in the multi-amplifier
systems have thermal switches connected to them which monitor the temperature of the
load and provide the over-temperature fault, if it occurs, through the system metering
board to the exciter/driver drawer.
The On Channel RF output of the amplifier drawer either connects directly to the digital
mask filter and low pass filter and then to the antenna in single amplifier systems or to a
combiner, the digital mask filter, low pass filter, output coupler and finally to the
antenna in multiple amplifier systems. The output coupler provides a forward and a
reflected power sample to the system metering board which detects the samples and
supplies the forward and reflected power levels to the exciter/driver drawer for use in
the metering circuits.

Instruction Manual, Rev. 2 18
Pre-Filter Sample (Non-Linear Distortion)
The pre-filter sample from the pre-filter coupler connects to (J3), the RF input 1 jack,
located on the rear panel of the driver drawer. This sample connects to the modulator
board where it is used in the correction system.
Post-Filter Sample (Linear Distortion)
The post-filter sample from the post-filter coupler connects to (J4), the RF input 2 jack,
located on the rear panel of the driver drawer. This sample connects to the modulator
board where it is used in the correction system.
IMPORTANT NOTES:
RF feedback sample lines must not be disturbed when adaptive pre-correction is
enabled. If a sample line is removed, the appropriate pre-correction mode must first be
disabled and only re-enabled after the feedback signal is re-connected. RF feedback
sample #1 is feedback for the non-linear pre-corrector system and sample #2 is used
for the linear pre-corrector system.
The adaptive pre-correction systems are likely to be significantly affected if the sense
port is moved to another coupler port with a different level or if a sample level is
changed significantly (a few dB). If the linear pre-corrector system is exposed to this
scenario it may generate a notable ripple in the output that may translate into an
increase (or decrease) of the measured RMS level. Should this situation occur, the only
way to restore proper operation is to reset the linear corrector using the controller's 'Set
To Neutral' command or the web interface's 'Reset Current Curve To Factory' command
and allow the pre-corrector system to start over again.
The On Channel RF output of the amplifier drawer either connects directly to the low
pass filter and digital mask filter and then to the antenna in single amplifier systems or
to a combiner, pre-filter coupler, low pass filter, the digital mask filter, post-filter output
coupler and finally to the antenna in multiple amplifier systems. The post-filter output
coupler provides a forward and a reflected power sample to the system metering board
which detects the samples and supplies the forward and reflected power levels to the
exciter/driver drawer for use in the metering circuits.

Instruction Manual, Rev. 2 23
If your system contains an optional preamp check that the 24VDC power supply is
connected to the preamp and an AC source.
Multi Amplifier Drawer Systems
If your system is a CU1TD/RD-1, CU1TD/RD-2 or CU1TD/RD-3, it also contains one
amplifier drawer. In CU2TD/RD and higher power systems, multiple amplifier drawers
are included. Each amplifier drawer is configured for 230 VAC operation only. Check
that the ON/OFF circuit breaker in the CU1TD/RD-1 amplifier drawer, or circuit breakers
in N+1 amplifier drawers, CU1TD/RD-2 or CU1TD/RD-3, located on the rear panel on
either side of the AC power jack, are OFF. Connect the AC power cord supplied with the
drawer from J10 on the rear of the drawer to the 230 VAC source. Refer to Table 1 for the
typical voltage and current requirements for CX Systems.
AC Distribution Box
If the system is mounted in a rack, an AC distribution box wired to a quad receptacle box
is used to connect the AC to the individual drawers. The AC distribution box is mounted
on the upper right side of the rack accessed through the back of the rack.
The main AC input for a C1TD-1 transmitter is, 195-253VAC, at least 10Amps, 50/60Hz.
The customer should provide a single point disconnect for the main AC input that connects
to the transmitter.
The AC input lines connect inside the AC distribution box by first removing the two screws
that hold the cover plate to the front of the AC distribution box. Then connect the three
wire main AC input to the input lugs, L1 to L1, L2 to L2 and Ground to Ground.
The power amplifier drawer and the quad receptacle box connect through AC power cords
directly to the AC distribution box. The AC power to the optional receiver drawer and the
exciter/driver drawer are connected through AC power cords that plug into the quad
receptacle box.
AC Distribution Panel
If the system is mounted in a cabinet, an AC distribution panel is supplied to connect the
AC to the individual drawers. The AC distribution panel is mounted facing the rear of the
cabinet and accessed through the back of the cabinet.
The main AC input for a CU2TD transmitter is, 195-253VAC, at least 30Amps, 50/60Hz.
The customer should provide a single point disconnect for the main AC input that connects
to the transmitter.
The AC input lines connect to the AC distribution panel by first removing the four #8
screws that hold the cover plate to the front of the AC distribution panel. Then connect
the three wire main AC input to the input lugs located at the top left of the AC distribution
panel, L1 to L1, L2 to L2 and Ground to the Ground lug on the left.

CX Exciter/Driver Input and Output Connections
The CX drawer (CU0TD/RD-1 thru CU0TD/RD-5 system as well as the CU2TD/RD-1
system and higher) rear panel includes a number of input, output and serial connectors
that require the user to connect cables to when installing the drawer.
When configured as an RD system, the drawer accepts an On Channel RF signal. When
configured as a TD system, the drawer accepts an ASI or SMPTE 310M input. In each
case, the drawer outputs a digital On Channel RF signal.
When the system had been configured as a complete rack/cabinet mounted transmitter
system, cables have been installed in the rack/cabinet and hang loosely near the rear
panel of the CX drawer when it is pushed all the way into the cabinet. Each cable has
been labeled to simplify installation. Please refer to Figure 6 and Table 3 for the locations
and information on the CX drawer rear panel connectors.
If your system contains the Optional Internal GPS Kit, the output of the GPS Antenna
connects to the J5 TNC connector on the rear panel of the CX drawer.

NOTES:
1) If your transmitter (TD) system contains an Optional ASI to S310 Converter, connect
the ASI output of the STL to the ASI in jack on the rear panel of the converter. Connect
the SMPTE-310 Output from the SMPTE 310 Out jack on the rear panel of the converter
module to the input jack J1 on the rear panel of the CU0TD/RD-1 thru CU0TD/RD-5
drawer or the driver drawer for the CU1TD/RD-1 and higher power systems.
2) If your transmitter (TD) system contains an Optional K-Tech receiver, connect the RF
from the receive antenna or one output of the splitter to the input jack J1 on the rear
panel of the K-Tech receiver. Connect the SMPTE 310 Out jack J2 on the rear panel of
the K-Tech receiver to the input jack J5 on the rear panel of the CU0TD/RD-1 thru
CU0TD/RD-5 or the driver for the CU1TD/RD-1 and higher power systems.
3) If the system contains the optional K-Tech back up system, the K-Tech receiver is
bypassed by using the second output of the splitter that connects to J1 on the rear panel
of the CU0TD/RD-1 thru CU0TD/RD-5 or the driver drawer and connecting a jumper
from J4 to J5, after removing the cable from the K-Tech receiver, on the rear panel of
the CU0TD/RD-1 thru CU0TD/RD-5 or the driver drawer. This configuration uses the
8VSB demodulator board in the CU0TD/RD-1 thru CU0TD/RD-5 or the driver drawer to
produce the SEMTE-310 signal.
4) If the system contains an optional preamp it connects to the output of the receive
antenna and to J1 on the rear panel of the CU0TD/RD-1 thru CU0TD/RD-5 drawer.
5) RF feedback sample lines must not be disturbed when adaptive pre-correction is
enabled. If a sample line is removed, the appropriate pre-correction mode must first be
disabled and only re-enabled after the feedback signal is re-connected. RF feedback
sample #1 is feedback for the non-linear pre-corrector system and sample #2 is used
for the linear pre-corrector system.
6) The adaptive pre-correction systems are likely to be significantly affected if the sense
port is moved to another coupler port with a different level or if a sample level is
changed significantly (a few dB). If the linear pre-corrector system is exposed to this
scenario it may generate a notable ripple in the output that may translate into an
increase (or decrease) of the measured RMS level. Should this situation occur, the only
way to restore proper operation is to reset the linear corrector using the controller's 'Set
To Neutral' command or the web interface's 'Reset Current Curve To Factory' command
and allow the pre-corrector system to start over again.
CX Driver/Exciter Input Connections
Connect the On Channel RF Input (RD) –78 to –8 dBm signal, or the ASI Input or the
SMPTE-310 Input to the 50Ω BNC input jack (J1 or J5) located on the rear panel of CX
drawer.
If used, connect the external 10 MHz reference input to the 50Ω BNC 10 MHz input jack
(J6) located on the rear panel of the CX drawer.
If used, connect the external 1 PPS reference input to the 50Ω BNC 1 PPS input jack (J7)
located on the rear panel of the CX drawer.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Unpacking, Installation &

Instruction Manual, Rev. 2 27
If used, connect the external forward power sample from the pre-filter coupler to the
50Ω BNC Input C jack (J3) located on the rear panel of the CX drawer.
If used, connect the external forward power sample from the post-filter coupler to the
50Ω BNC Input D jack (J4) located on the rear panel of the CX drawer.
If your system contains the Optional Internal GLONASS or GPS Kit, the output of the
GPS Antenna connects to the (J5) TNC connector on the rear panel of the CX drawer.
This kit supplies 10 MHz and 1 PPS references for use in the CX drawer.
In Translator (RD) systems there is a SMPTE-310 loop-thru from the output of the
Demodulator Board at J4, mounted on the rear panel of the transmitter or driver drawer,
to the input to the Modulator Board at J5, mounted on the rear panel of the transmitter
or driver drawer. There is a jumper installed from J4 to J5. To feed SMPTE-310 directly
to the Modulator Board, remove the jumper and insert SMPTE-310 into J5. This is only
used in Translator (RD) systems not Transmitter (TD) systems.
CX Driver/Exciter Output Connections
The digital RF On-Channel output of the CX drawer is the (J9) 50Ω “N” connector RF
output jack located on the CX drawer rear panel.
CX Driver/Exciter Single Drawer Output Connections
In CU0TD/RD-1 thru CU0TD/RD-5 systems, the output of the CX drawer at J9 connects
to the low pass, digital mask filter and then to the antenna for your system.
CX Driver/Exciter Multi Drawer Output Connections
In CU1TD/RD-1 and higher power systems, the output of the CX drawer at J9 is
connected to J1 the 50 Ohm “N” connector RF input jack located on the rear panel of the
amplifier drawer or to a splitter in multiple amplifier systems.
In CU1TD/RD-1, CU1TD/RD-2 or CU1TD/RD-3 systems, check that the system power
metering interface cable is connected from J11 the 9 position “D” connector located on
the rear panel of the driver drawer to J4 the 9 position “D” connector located on the rear
panel of the amplifier drawer. This cable provides the control, status and operating
parameters of the amplifier drawer to the driver drawer.
In CU2TD/RD and higher power systems the output of the driver drawer is split and
connected to J1 the “N” type connector RF input jack on the amplifier drawers. Check
that the system power metering interface cable is connected from J11 the 9 position “D”
connector located on the rear panel of the driver drawer to J9 the 9 position “D”
connector located on the System Metering Board. Also check that the serial connection
is cabled from the RJ-45 connector J13 on the driver drawer to the RJ-45 connector J1
on the system metering board. The system metering board provides serial RJ-45
connections at J2 and J5 that are cabled to the RJ-45 serial port J5 on the rear panel of
the amplifier drawers. These cables provide the control, status and operating
parameters of the amplifier drawers to the driver drawer through the System Metering
Board.

Power Monitoring Connections to J11
In systems with one or more external amplifiers, J11 is used to communicate the output
forward and reflected metering voltages back to the driver. J11 is connected directly to
the external amplifier when there is only one external amplifier and is connected through
the system metering module when multiple external amplifiers are used.
In multiple external amplifier systems there are thermal switches mounted on the output
combiner reject loads. The reject load interlock is connected to thermal switches and is
used to shut down the system if the reject load overheats. In systems with no external
amplifier, the only connection used is the Reject Load Interlock, which must be
connected to Supply Return using a jumper from J11-6 to J11-9.

HPA Output Connections
The amplifier drawer digital RF On-Channel output is at the (J12) 50Ω “7/16” (1.1cm)
DIN RF output jack, located on the rear panel of the drawer. The RF output jack is
connected to the low pass filter, digital mask filter, then to the antenna for your system
in single amplifier systems.
In multiple amplifier drawer systems, the outputs of each drawer is connected to a
combiner and then the low pass filter, digital mask filter, output coupler and finally to
the antenna for your system.
The output coupler provides a forward and a reflected power sample that are cabled to
the System Metering Board at J8 reflected and J3 forward. Also connected to the
system metering board at J10-6 & 9, is the output of the over-temperature switch
mounted to the reject load that is used as the reject interlock by the system. The
samples and interlock are fed through J9 on the system metering board to J11 on the
driver drawer. This completes the connections of the system.
Connecting your Transmitter to a TCP/IP Network
To connect your transmitter to a TCP/IP Network you must set up the IP address, subnet
mask, and gateway values of both the Ethernet controller and the modulator. DHCP is
not available for the Ethernet controller but it can be turned on for the modulator
controller. However, both devices should use static IP addressing so that these values
remain constant after a power cycle. Refer to Figure 54.1.13 on Page 103 for setting up
the Ethernet controller and see Figure 31 on Page 67 for setting up the modulator
Network parameters.
If the transmitter system is pre-wired at the factory and includes a router, the router’s
WAN port should be the connection point to the network. The user must configure the
router’s WAN port for access to the network.
Note: All other devices (Remote Interface panel and CX Exciters) connected to
the router have been configured with a static IP address. The operator can
access the other devices though the router, but the IP addresses must not be
changed. Changing the static IP addresses could prevent communication
between the devices and render the transmitter inoperative.
Contact your local IT administrator for the proper TCP/IP address subnet mask and
gateway settings of your network.

Instruction Manual, Rev. 2 32
Maintenance
The Innovator CX Transmitters are designed with components that require little or no
periodic maintenance, except for the routine cleaning of air intakes, fans and module front
panels as well as the periodic check of general tightness of hardware.
It is recommended that periodically (the time interval depends on the amount of
movement the cabinet receives) all mounting hardware, holding drawer slides, shelving
and mounting plates inside the cabinet are checked for tightness. All screws and bolts
that are accessible should be tightened initially when the transmitter is received and
periodically thereafter if the transmitter is moved by vehicle. All coaxial connectors, hard-
line connections and hardware holding combiners, splitters, or any other mounted items
should be checked and tightened.
The amount of time between cleanings of the drawers and cabinets depends on the
conditions within the transmitter room. While the electronics have been designed to
function even if covered with dust, a heavy buildup of dust, dirt, or insects will affect the
cooling of the components. This could lead to a thermal shutdown or the premature
failure of the affected drawer. When the front panels of the drawers become dust
covered, the drawer should be pulled out and any accumulated foreign material should be
removed.
NOTE: To remove a drawer from the cabinet, the input and output cables must be
removed from the rear (and/or front) of the transmitter before the drawer can be pulled
out completely from the cabinet.
A vacuum cleaner, utilizing a small, wand-type attachment, is an excellent way to suction
out any dirt from the drawer and cabinet. Alcohol and other cleaning agents should not
be used unless you are certain that the solvents will not damage components or the silk-
screened markings on the drawers and boards. Water-based cleaners can be used, but do
not saturate the components. The fans and heatsinks should be cleaned of all dust or dirt
to permit the free flow of air for cooling purposes.
It is recommended that the operating parameters of the transmitter be recorded from
the LEDs and the LCD system metering on the front panel of the drawer at least once a
month to be used for comparison purposes in case of a failure. It is suggested that this
data be retained in a rugged folder or envelope and stored near the transmitter.

ATSC Transmitter/Regenerative Translator
Instruction Manual, Rev. 2 34
8VSB ATSC Modulator Board
The Modulator design is based on the Advanced Universal Modulator board, customized
to comply with ATSC standards A/53, A/54 A/64, A/110 and A/153.
The modulator converts an MPEG-2 transport stream to an 8-VSB modulated RF signal.
Using a new direct digital conversion process, the modulator is able to provide an RF
output that covers a standard frequency range of 470 MHz to 1 GHz with superior
shoulders and MER. Optionally, the modulator can be configured with an IF frequency
range of 30 MHz to 100 MHz or a RF frequency range of 30 MHz to 1 GHz.
The modulator supports ATSC features such as 8-VSB modulation, ATSC M/H processing,
MFN network mode and SFN network modes with Distributed Transmission.
The modulator comes equipped with Adaptive Non-linear and Linear Digital Pre-
correction that provide compensation for the non-linear distortions produced by a High
Power Amplifier and the group delay introduced by an output filter. The Adaptive Pre-
correction support continuous or single run adaptation, provides MER, Peak to Average
Ratio, Upper Shoulder, Lower Shoulder and Group Delay measurements and allows the
user to store curves on the modulator. The modulator also features Manual Non-linear
and Linear Digital Pre-correction.
The modulator Controller functions are performed by an embedded controller, based on
the PowerPC™ (IBM) processor. The Controller provides all external communication
interfaces as well as internal board and peripheral controls. CLI, Web GUI, SNMP and
Machine-to-Machine interfaces are all supported. Full remote management and control
as well as remote firmware and software upgrades are provided.
Control and Communication
The modulator can be controlled and monitored locally (on-site), or remotely from a
Network Management System (NMS).

There are two interface ports provided for control and communication:
• Ethernet Port (RJ-45) – used for local control with a laptop PC and remote access
through a LAN. Web GUI, SNMP and CLI (Telnet and HyperTerminal) protocols
are supported.
• USB Port (Type B) – used for local control, initial setup, status information and
troubleshooting with a laptop PC. A Command Line Interface (CLI) is the
supported protocol.
SNMP
The modulator SNMP interface provides the means for remote management of the
modulator and to accept alarm traps. The notification options can be configured on a
per-alarm basis. The user may decide to mask certain alarms, increase/decrease
integration time to declare an alarm, etc. Alarm and event logs are available via the
SNMP interface and are stored in Non Volatile Memory.

Web GUI
The modulator hosts an internal web interface (Web GUI) accessible through its Ethernet
port. The Web GUI is an intuitive interface allowing the user to access the current
modulator status and configure the operational parameters of the system. The Web
interface uses a simple hierarchical menu structure which provides access to all
modulator parameters.
For a detailed description of the Web GUI interface refer to Web GUI Interface.
CLI
The CLI allows the user to access the current modulator status and configure the
operational parameters of the system. The CLI uses a simple hierarchical menu
structure which provides access to all modulator parameters.
For a detailed description of the CLI interface refer to CLI (Command Line Interface).
Local Access
The modulator can be controlled and monitored locally (on site) through the Ethernet
Port and/or the USB port with a laptop PC.
The Ethernet port provides access to the Web GUI and CLI through Telnet. The USB
port provides access to the CLI, which allows the operator to perform initial
setup/troubleshooting when network connectivity is not available or desired.
Remote Access
The Network Management System (NMS) operator can control and monitor the
modulator remotely through the Ethernet port and LAN using the Web GUI and/or SNMP
interfaces.
To facilitate the remote control of several modulators, each modulator may be
individually named (16 characters). This “name” is available on the control interfaces.
Network Parameters
The network parameters need to be configured properly to communicate with the
modulator on an IP network. This is required to access the Web GUI, SNMP or the CLI
on Telnet, as well as for upgrading the main software components.
If the default network settings are known and want to be changed, the user can do so
with the Web GUI – see Figure 31 for details.

Transport Stream Inputs
DVB-ASI Inputs
The DVB-ASI inputs accept an MPEG-2 transport stream according to DVB
recommendations. Both 188 and 204 byte transport packets are supported.
Automatic switching provides near seamless switching to a secondary transport stream if
the primary transport steam source fails.
SMPTE 310M Inputs
The SMPTE 310M input accept a MPEG-2 transport stream.
Note: The SMPTE 310M inputs are an optional feature of the ATSC modulator.
Modulator Operating Modes
The modulator operating modes are Normal and CW. In Normal mode, the modulator
generates a complete ATSC (8-VSB) waveform. In CW mode, the modulator generates
a narrow-band frequency tone.
ATSC M/H Mode
The modulator can be configured to process incoming M/H packets created by an M/H
pre-processors.
Network Modes
The modulator can be configured for MFN or SFN network operation.
RF Output
The RF output covers a frequency range of 470 MHz to 860 MHz in 1 Hz steps.
Windowing (Window Enabled)
The windowing function is a raised cosine window that reduces the modulation sidebands
of the COFDM spectrum. It may be enabled or disabled.
Internal Frequency Reference
The modulator is equipped with an internal reference frequency that has a stability of ±
0.05ppm, suitable for MFN Mode. Where higher accuracies are required, an external 10
MHz reference signal must be applied to the 10 MHz external reference input.

Manual Digital Linear and Non-linear Pre-correctors
The modulator is equipped with digital linear and non-linear pre-correctors (pre-
distorters) that can significantly improve the performance of a transmitter. The Pre-
corrector function can be switched on and off from the Web GUI or CLI.
The Non-linear pre-corrector compensates for power amplifier non-linearity and is able
to provide a separate adjustment for the low and high frequency shoulders of the wide
channel spectrum. Additionally the non-linearity corrector may serve as peak limiter in
order to control peak to average power ratios. The Linear pre-corrector compensates for
the group delay created by an output filter.
The input-gain of the Pre-corrector can also be used to adjust the power-level of a
transmitter.
CAUTION!
Adjusting the input-gain of the Pre-corrector and thereby the power-level of
the transmitter must be carried out with the utmost care, since higher than
normal levels may cause damage to the transmitter.
The construction of the Pre-corrector curve is aided by a software application that
provides a graphical user interface to the Pre-corrector curve. Combined with a
spectrum analyzer on the transmitter output, a repetitive process can be carried out to
optimize the pre-corrector curve to the actual transmitter.
In addition to being a highly effective tool for creating pre-correction curves, the UBS-
Axcera Corrector GUI has extensive features for storing and retrieving pre-correction
curves to and from the PC storage medium (for example hard disk drive). The UBS-
Axcera Corrector GUI also allows storing and retrieving up to ten linear and non-linear
curve presets to and from the modulator.
The Manual for the Digital Pre-Corrector GUI Software describes in detail the
operation of the Pre-corrector.
Adaptive Non-linear and Linear Digital Pre-correction
The modulator is equipped with Adaptive Non-linear and Linear Digital Pre-correction
that provides compensation for the non-linear distortions produced by a high power
amplifier and the group delay introduced by an output filter.
High power amplifier and band pass filter feedback (reference) signals are
downconverted to 25 MHz IF before the “adaptation process” or “cycle” begins.
The “adaptation process”, or “cycle”, includes set-up of the capturing cycle, the
capturing of data, signal measurements, the calculation of NLP/LP coefficients and the
transfer of coefficients and signal measurement to the modulator board.
Once the capturing cycle is set up, the downconverted HPA or BPF reference signal is
sampled by an ADC and stored in a local memory buffer for the processor to read upon
completion of the data capturing process.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator
ATSC Transmitter/Regenerative Translator
Instruction Manual, Rev. 2 38
The processor compares the captured data to the ideal waveform curves (stored on the
capture card) and calculates NLP or LP coefficients. The coefficients are then transferred
to the modulator board for control of the back-end Non-linear or Linear Digital Pre-
corrector. A number of signal measurements, including MER, Peak to Average Ratio,
Upper Shoulder, Lower Shoulder and Group Delay are also transferred to the modulator
board and are displayed by the modulator interfaces (Web GUI, CLI).
Web GUI Interface
Introduction
The modulator parameters can be reviewed or changed using the Web GUI interface.
The Web GUI is an intuitive interface allowing the user to access the current modulator
status and set up the operational parameters. The Web GUI interface uses a simple
hierarchical menu structure which provides access to the modulator parameters though
a series of pull down menus.
The modulator needs to be assigned an IP address in order to access the Web GUI. The
modulator is shipped from the factory with a default IP address, but the user will need to
configure the IP address of each unit for local network access. The IP address can be
accessed and modified from the front panel or CLI.
Login
• Open a Web browser window (Internet Explorer, Firefox, etc.) and enter the
modulator IP address. For example: http://172.20.30.210/.
• The first menu page is the login page.
• The User Name field must be kept blank, while the default password for normal
access is “admin”

The available parameters in MFN Mode are:
Item Selection
MH Enable OFF, ON
If this parameter is set to ON, ATSC-MH waveform
support will be enabled.
SFN OFF, ON
If this parameter is set to ON, the modulator will operate
in SFN mode and a number of additional parameters can
be edited by the user.
Table 8: MFN Transmission Parameters
When the modulator is used in conjunction with a UBS DTx Adapter, the user must
configure the modulator’s Transmitter ID (tx_address) correctly, so that the TCP
command information used to address the individual modulator (transmitter) is
extracted.
The Transmitter ID is a 12-bit unsigned integer, with a user configurable range of 0 to
4095. The Transmitter ID’s decimal value is equal to the DTx Adapter’s three character
hexadecimal string, which is determined by the DTx Adapter’s tx_group_ number and tx
id.
For example, a tx_group_number of “AB” and a tx id of “9”, would generate a 3
character hexadecimal string of “AB9”. In this case, the user must enter a Transmitter
ID of 2745. A tx_group_number of “DE” and a tx id of “15”, would generate a 3
character hexadecimal string of “DEF”. In this case, the user must enter a Transmitter
ID of 3567.

Digital Adaptive Pre-corrector
The Digital Pre-corrector page allows the user to configure the capture card cycle
(adaptation process) settings and store the NLP and/or LP Profiles (coefficients) into
memory.
Pre-correction Set-up
The user should first select which pre-correction cycles will be run by configuring the
“NLP/LP Selection” parameter. The user may select Non-linear Pre-correction (NLP),
Linear Pre-correction (LP) or both. The user should also select how many NLP cycles will
run for every LP cycle. When the modulator is synchronized with a 1PPS reference
signal (from a GPS receiver), the user can offset the cycle start time, relative to the
1PPS signal.
Note: The NLP cycle will always run before the LP cycle when both cycles are selected.
The user must then select the “NLP Method” to determine which pre-correction algorithm
is used. The user should first try “Regression” mode. If the results are undesirable, the
user should then try “RLS” mode, then “Legacy” mode.
The user must then select the “Mode” parameter and set the “Precorrection” parameter
to “Run” to start the cycle(s) (adaptation process). When the “Mode” parameter is set
to Adaptive, the NLP and/or LP coefficients will be optimized constantly. When the
“Mode” parameter is set to “Single Operation”, the NLP and/or LP coefficients will only be
optimized once.
If the “Precorrector” parameter is set to “Stop”, the NLP and/or LP cycles will stop, with
the last calculated coefficients being used. In other words, the cycle(s) will stop, but the
Non-linear Pre-correction and/or Linear Pre-correction will not be disabled. To disable
the pre-correction, the “Precorrection” parameter must be set to “Stop” and “Reset
Precorrector” must be set to “ON”. Setting “Reset Precorrector” to “ON” while the
cycle(s) have stopped will clear the NLP and LP coefficients.
Note: Any time a parameter is changed (i.e from NLP to NLP/LP) the user should first
Stop the Precorrection then Reset the Precorrection prior to changing the parameter.
This excludes saving NLP or LP profiles.
Storing a Profile (Curve) to Memory
To store the active Profile (coefficients) to memory, the user must set “Save Adaptive
NLP Profile” or “Save Adaptive LP Profile” to “ON”. Before saving, the user should
configure the “Profile Name” and “Profile Number” accordingly.
Loading a Profile (Curve) from Memory
A NLP or LP Profile can be loaded from memory using the Non-linear or Linear Pre-
corrector pages – see the Non-linear and Linear sections. The user must select the
desired profile from the NLP or LP Profile pull-down menu and ensure that the NLP or LP
State is set to “ON”.

Instruction Manual, Rev. 2 53
Note: If the user has saved a profile (curve) to memory and decides to stop the
Adaptive Pre-correction process, the user should navigate to the Non-linear and/or
Linear Pre-corrector pages and select the desired profile from the pull-down menu and
ensure that the state is set to “ON”. This will ensure that Non-linear and/or Linear Pre-
correction is enabled following a modulator reset and that the correct profile (curve) is
loaded.

CLI (Command Line Interface)
Introduction
The modulator can be controlled and monitored from the Command Line Interface (CLI)
in addition to the Web GUI.
The CLI is accessible from the USB port via a HyperTerminal session or from the
Ethernet port via Telnet or HyperTerminal sessions.
Using the USB Port to Access the CLI
The modulator must be connected to a laptop PC using a USB-to-USB cable. The cable
will require a USB Type B connector to mate with the modulator USB port, while the
other connector has to mate with the laptop PC USB port.
Open a HyperTerminal (or HyperACCESS depending on the operating system) session on
the laptop PC and set the parameters as shown below.
Figure 43: Com Settings
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator
ATSC Transmitter/Regenerative Translator
Instruction Manual, Rev. 2 70
Using the Ethernet Port to Access the CLI
The modulator can be connected directly to a laptop PC or through a hub/switch using
an RJ-45 straight-through cable.
The modulator and laptop PC must be configured to be on the same IP network so that a
connection can be established.
A Telnet client can be opened from the “Start/Run” button on the laptop PC. Enter the
IP address assigned to the modulator followed by the number 26 – see below.
Figure 44: Starting the Telnet Session
A HyperTerminal session can also be used to access the CLI through the Ethernet port –
see Figure 43.
CLI Login Procedure
1. Once the connection has been established, press enter to get to the login prompt.
2. Enter the password and press enter. Note: The password is “admin” by default,
but can be changed through the Web GUI, CLI or SNMP.
3. After the password has been verified, the main menu will appear.

CLI Menu System
The CLI contains a four level menu system where system parameters can be viewed and
changed.
Navigation
Each menu has been assigned a numeric value for navigation purposes. To navigate
through the CLI menu system, enter the number assigned to the desired menu.
Depending on the menu accessed, the user may have the option to enter a sub-menu,
or change a system parameter.
The following menu prompts are available for navigation and for changing system
parameters:
• Enter Selection – allows the user to change menus or exit the CLI
• Enter New Value – allows the user to change a system parameter
At the “Enter Selection” prompt, the user may also use the following keys to navigate or
exit the CLI menu system:
• r – return to the previous menu
• e – exit the CLI
If the user accesses the “Enter New Value” prompt by mistake or decides that they do
not want to change a parameter, the prompt can be exited without making a parameter
change. Simply clear all alphanumeric parameters and press enter. See the following
example below:
Current Value: Auto
Range :
0. A
1. B
2. Auto
Enter New value:
No Changes
Parameter Values
In some cases, such as entering the Guard Interval or Constellation, the selectable
parameters have been assigned a numeric value. This allows the user to change the
parameter by simply entering the number assigned to a different parameter.
In other cases, such as entering the modulator IP address or Site Information, the user
can enter a range of alphanumeric characters.
All parameter changes are made at the “Enter New Value” prompt.

SNMP
The modulator supports a SNMP interface for remote management of the modulator via
a SNMP Network Management System (NMS). Refer to SNMP Parameters and NMS
Users Menu on how to use the Web GUI to configure the SNMP interface and set up a
NMS user account.
Once the SNMP interface is established it is possible to use standard SNMP Network
Managers (e.g., SNMPc, HP OpenView etc.) or a custom SNMP Network Manager for
SNMP access. SNMP Traps can be emitted for each of the possible modulator alarms.
The required Management Information Base (MIB) file for the modulator SNMP interface
can be included on the manual CD delivered with the unit and is available upon request.
The SNMP parameters list is nearly identical to those used in the Web GUI and CLI. The
exceptions are the controls for creating a NMS User account and the management of
modulator configuration files for backup or software upgrades. This set of functions is
purely local to each modulator and is not suitable for SNMP global access. Of course,
these functions are still accessible for remote access via the system web interface or CLI
interface.
Below is the menu tree for the web interface. The items enclosed in a grey box are
excluded from the SNMP interface. All other menu items are accessible via SNMP.

Instruction Manual, Rev. 2 82
Initial On Site Turn-On Procedure
After the Innovator CX Series drawer or drawers are installed and all input, output and AC
connections are made, the system is ready for the initial on site turn on. Check that the
output of the transmitter is connected to an appropriate rated load or to the digital mask
filter and the antenna for your system. Check that the main AC power to the System is ON.
If your system contains an optional ASI to S310 converter module, K-Tech receiver drawer
or Axciter, check that they have AC connected to them and that they are turned ON.
NOTE: If your system is mounted in a cabinet and contains an optional UPS, check that the
ON/OFF button, located on the left side of the top panel of the UPS is On. The UPS is
normally mounted behind the removable blank panel, located immediately above the
exciter/driver drawer, which is held in place by four #10 Phillips head screws.
Single or Multi Drawer Systems
If you have a CU0TD-1 thru CU0TD-5 system, push ON the switch located on the rear panel
of the drawer above the AC power jack. The large fan mounted on the rear panel of the
drawer should operate.
If your system is a CU1TD/TD-1 or higher power system, switch ON the ON/OFF circuit
breaker(s), located on the rear panel of the amplifier drawer(s), mounted on each side of the
AC input power jack. The two fans mounted in the amplifier drawer should operate.
Place the system in Operate. The Operate/Standby LED and Status LEDs on the CU0TD-1
thru CU0TD-5 should be Green indicating the system is in Operate and performing normally.
The Operate/Standby LED showing Amber indicates the System is in Standby. The Status
LED showing a blinking Red LED indicates an Event (Fault) is occurring now. The Status LED
showing Amber indicates that an Event (Fault) occurred since the last time the Event (Fault)
indications were reset. NOTE: The modulator takes approximately 2 minutes to lock up for
normal operation. During this time the modulator status screen will blink warm up.
If your system is CU1TD/RD-1 or higher power, the Enable LED and Status LEDs on the
Amplifier Drawer should be Green indicating the system is in Operate and performing
normally. The Enable LED showing Amber indicates the System is in Standby. The Status
LED should be Green indicating no Events (Faults) in the system. If the Operate/Standby LED
shows Amber it indicates that the System is in Standby. If the Status LED is blinking Red it
indicates an Event (Fault) is occurring now. If the Status LED shows Amber it indicates that
an Event (Fault) occurred since that last time the Event (Fault) indications were reset. The
output power is factory set according to customer request and does not need adjusted. If a
problem occurs, call UBS-Axcera field support at 724-873-8100 for information on modifying
the power level of the system.
Once the modulator has finished its boot up process it can be configured for LAN access.
Using the Web GUI, navigate to the System parameters sub-menu where the Network
parameters can be configured. After changing any Network parameters, the modulator
must be reset. Navigate to the System parameters sub-menu System Reset page to reset
the modulator. The modulator can now be provisioned remotely through the Web GUI.

NOTE: The RF System Interlock is provided on J12, a 15 position “D” connector, located on
the rear panel of the CU0TD-1 thru CU0TD-5 drawer. The RF System Interlock at J12-5
provides the customer with a means of connecting the system to protection circuits, for the
loads, thermal switches, combiners, or the antenna, in the output of your system, that will
place the system in Standby if the protection circuit opens.
The Reject Load Interlock is provided at J11, a 9 position “D” connector. J11-6 provides the
customer with a means of connecting the system to protection circuits, for the reject load in
multiple amplifier systems, which will place the system in Standby if the protection circuit
opens. If the interlocks are not used in your system, a plug with a jumper from J12-5 to
J12-15, ground, for RF system Interlock and another plug with a jumper from J11-6 to J11-
9, for Reject Load Interlock, need to be connected. These jumpers provide the RF System
and Reject Load Interlocks, which allow the system to go to operate. Without the jumpers,
the system will remain in Standby.
Adaptive Pre-Correction Set-up Procedure
Adaptive Pre-correction is available as limited One-Touch Correction (OTC) or full feature
correction. With One-Touch correction the adaptive process can be enabled for one cycle
whereas full feature correction can be set to continuously adapt or automatically adapt
when performance characteristics indicate that a change is needed.

The user can access the transmitter's event log by selecting the 'View Events' button
on the CX Ethernet Controller main control/monitoring page.
Figure 57: Typical Event Log Page
This page allows the user to view events and to determine the time between events.
Events are logged in the order they are received. If more than 200 events are detected,
the transmitter's System Controller drops the oldest event to record the new event.
Transferring of events from the transmitter's System Controller and the Ethernet
Controller is scheduled so that device details are continuously monitored. Therefore the
event log page may update a few seconds behind the transmitter display when the log is
full or changing quickly.
Each event record indicates the event number, the number of events, an occurrence
counter and text describing the event. The occurrence counter keeps track of the
number of times a specific event has occurred since the log was last cleared. Up to 99
occurrences are available for each event.
To view the next set of twenty events, activate the 'Next' button. If viewing events

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC SNMP Ethernet
Transmitter/Regenerative Translator Interface Description
Instruction Manual, Rev. 2 106
SNMP Interfaces
The Innovator CX Ethernet Controller implements Simple Network Management Protocol
(SNMP). SNMP is a standardized method of transferring information from one electronic
device to another. SNMP is typically used to remotely control and monitor several
transmitter devices from a centralized network management system (NMS). SNMP is a
communication method between two applications and is not a graphical user interface.
Therefore, SNMP functionality is included along with web page server functionality.
SNMP is used to gather information or set control states but it requires additional
computer applications for operator monitoring and control.
The Innovator CX Ethernet Controller implements SNMP version 2 (SNMP v2), using a
Management Information Base (MIB). The MIB file defines all SNMP parameters of the
transmitter, specifies the format of data, and orders the presentation of the parameters
using a hierarchical namespace containing object identifiers (OID). Each OID identifies a
variable that can be read, read and set, or only set via SNMP commands.
SNMP functionality also provides for alert messages that are issued from the Ethernet
Controller to one or two network computers. A SNMP trap message is sent only once
and is not acknowledged by the receiving device. The Ethernet Controller issues a trap
message when data is added to the transmitter Event log (either activation of a fault or
when a fault is cleared), or when the transmitter operate/standby status changes.
SNMP Configuration
The Ethernet Controller's TCP/IP Address, Subnet Mask, and Gateway must be
configured with static values that are valid within your network. Dynamic Host
Configuration Protocol (DHCP) is not implemented; however access to these
configuration parameters is available through the front panel setup menus of the
Innovator CX drawer.
The Innovator CX drawer’s SNMP MIB allows up to two SNMP trap destinations. The trap
destination values can be set through WEB pages. The TCP/IP address of a trap
processing computer can also be configured through the SNMP parameters called
'site_trap_adr1' and 'site_trap_adr2'. To clear a previously configured trap destination
and cause the system not to issue traps to a specific address, set the value to
'000.000.000.000'.
Reading of SNMP values is done with the message's community access set to 'public'.
When setting SNMP values, a default community access level of 'private' is used. Future
implementations of the Ethernet SNMP agent may allow for the set community access
level to be defined through the device's web server.

Descriptions of Boards in the CU0TD/RD-1 thru CU0TD/RD-5 Systems
(A1) 8 VSB Demodulator Board (1308275)
NOTE: The 8 VSB demodulator board is only used in RD systems except when the
output of an external K-Tech Receiver is used.
Overview
The 8 VSB demodulator assembly receives an off air 8 VSB signal on any VHF or UHF
channel and demodulates this to an MPEG-2 transport stream that is per the SMPTE-
310M standard. The input to the assembly is at an “F” style connector on the shielded
tuner and can be at a level of –8 to –78 dBm. The tuner (TU1) down converts the RF
channel to a 44 MHz IF signal. This signal is the input to the digital receiver chip U1.
The digital receiver chip subsequently decodes the IF and delivers an MPEG-2 transport
stream on a parallel data bus to a programmable logic array, U8. U8 clocks the
asynchronous MPEG data from the receiver chip and outputs a synchronous data stream
at a 19.39 MHz rate to buffer/driver U11. U11 subsequently drives the output at J13 to
a lower level that is AC coupled out of the board.
Microcontroller Functions
A microcontroller, U17, is provided on this assembly to supervise the operation of the
receiver chip and the tuner. In addition, the microcontroller also interfaces to the front
panel LCD display via connector J24 and pushbutton interface on J27. On power up, the
microcontroller sets the tuner to the last channel that was selected when the unit was
powered down. In addition, the microcontroller also configures the digital receiver to
operate as an 8 VSB receiver. The communication between all of the devices on this
board is via an I2C serial bus that is local to this board.
Jumper and DIP Switch Settings
This board can be used in various assemblies. When this assembly is installed in the
Innovator CXB product, the jumpers on J7 and J8 should be placed between pins 2 and 3
for normal operation. The DIP switch SW1 should be configured as indicated in Table
12.

Figure 60: ALC Board Block Diagram
The ALC Board, Innovator CX Series, is used to control the RF drive power to the RF
amplifier chain in the CU0TD/RD-1 thru CU0TD/RD-5 systems. The board accepts an 8-
VSB RF input signal at a nominal input level of -3 dBm average power and amplifies it to
whatever drive level is necessary to drive the final RF amplifier in the drawer to full
power. The input signal to the board at J1 is split by U4, with one half of the signal
driving a PIN diode attenuator, DS1 and DS2, and the other half driving a detector, U13,
that is used to mute the PIN attenuator when there is no input signal. The output of the
PIN attenuator is sent to two cascaded amplifiers, U2 and U3, which are capable of
generating +10 dBm average power from the board at J2.
The PIN attenuator is driven by an ALC circuit or by a manual fixed voltage bias,
depending on the position of switch S1. When the switch is pointing to the left, looking
from the front of the drawer, the ALC circuit is enabled. When the switch is pointing to
the right, the ALC circuit is disabled and the PIN attenuator is controlled through the
Manual gain pot R62. When the switch is in either ALC or manual, the voltage in the
unused circuit is preset low by the circuitry connected to pins 4-6 on SW1. This allows
the RF power to ramp up slowly to full power when the switch changes positions. CR8,
C33 and associated components control the ramp up speed of the manual gain circuit.
CR9, C42 and their associated circuits do the same thing for the ALC circuit. The
practical effect of this is to preset the RF drive power to near zero output power when
enabling and disabling the ALC, followed by a slow controlled ramp up of power.
The ALC circuit normally attempts to hold the drawer output power constant, but there
are four faults that can override this. These faults are Input Fault, VSWR Cutback Fault,
VSWR Shutdown Fault and Overdrive Fault.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Board Descriptions
Transmitter/Regenerative Translator
Instruction Manual, Rev. 2 110
The Input Fault is generated by comparator U7C and presets the PIN attenuator and ALC
circuit to maximum attenuation whenever the input signal drops below about -7 dBm.
Test point TP2 allows the user to measure the detected input voltage.
The VSWR cutback circuit is set so that the ALC circuit will start reducing RF drive once
the Reflected power reaches a level of about 6% and will keep reducing the drive to
maintain that level. The cutback is generated by U8A, U8B and their associated
components that diode-or the metering voltages. The forward power is scaled to 2V =
100 % and the reflected power is scaled to 2V = 25%. The Reflected metering voltage
is doubled again by U8B so that when the voltage of U8B exceeds the voltage at the
output of U8A, the reflected power takes over the ALC circuit. Once the U8B voltage
drops below the forward power at U8A, the forward power takes over again.
The VSWR shutdown circuit will shut the drawer down if the Reflected power increases to
15% or higher, which can happen if the drawer sees reflected power when the ALC is in
manual.
The Overdrive protection looks at a sample of the RF signal that is applied to J1 of the
board. The peak level of this signal is detected and can be measured on TP1. This
voltage is applied to a comparator with the threshold set by R38. If this threshold is
exceeded, the ALC circuit mutes then ramps up to try again. This circuit also works in
manual gain as well.

Board (1310282 and the (A6-A2) the BL881 Single Stage Amplifier Board (1314882).
The assembly has approximately 35 dB of gain.
(A6-A1) 1 Watt UHF Amplifier Module (1310282)
This board is normally operated at a power of 200 mW pk sync or lower. It consists of
two AH202 MMICs operating in parallel. The board is powered by +12 VDC and has no
adjustments. The amplifier module has a gain of approximately 17 dB.
(A6-A2) BLF881 Single Stage Amplifier Board (1314882)
This board consists of a single stage amplifier operating at +48 VDC. The board has an
overall gain of about 16 dB. The input to the board passes through a 3 dB attenuator
consisting of R11-R13, and then is applied to the gain stage, which consists of a single
LDMOS transistor Q1 operating in Class AB. The bias voltage for the transistor is
generated through the voltage regulator U1, and is adjusted using pots R2 and R3. The
Diode CR1 provides temperature compensation for the transistor. The transistor will
output over 40 Watts pk sync, but is typically used in a driver application at much lower
output powers. The Directional Coupler U2 provides a 20 dB down sample of the RF
output at the SMA Jack J4.
(A6) Amplifier Assembly (1312566) – Used in CU0TD/RD-2
The (A6) Amplifier Assembly (1312566) is made up of (A6-A1) the 2 Stage UHF
Amplifier Board (1308784) and (A6-A2) the RF Module Pallet, Philips, High Output
(1309580). The ALC Board (1315006) is also part of this assembly. The assembly has
approximately 36 dB of gain.
(A6-A1) 2 Stage UHF Amplifier Board (1308784)
The 2 Stage UHF Amplifier Board, (1308784) consists of a driver stage and a parallel
connected final amplifier stage which have a total gain of approximately 23 dB. The
working point settings for the 2 Stage Amplifier Board are factory set using the
potentiometers R32 for Q2, R15 for Q1, and R24 for Q3 and should not be altered. The
input RF connects to the first amplifier stage U2, which has a gain of approximately 14
dB. The output is split by U2 and connected to the final amps. The final amplification
circuit consists of parallel-connected push-pull LDMOS amplifier circuits Q1 and Q3
operating in class AB each with approximately 14 dB of gain. The board uses a power
supply voltage of 28-32V. The RF transistors are operated at a voltage of 24V
generated by the voltage regulators U1 for Q1, U5 for Q3 and U6 for Q2, which provide
a separate regulated voltage to each transistor. In order to match the LDMOS
impedance to the characteristic impedance of the input and output sides, matching
networks are located before and after the amplifier circuits. The hybrid coupler U2 splits
the input to the parallel amplifiers and the hybrid coupler U4 combines the amplified
outputs. The combined output connects through a directional coupler to J1, the RF
output jack of the board. The directional coupler provides an RF sample at J3 that is
used by an external overdrive protection circuit located on (A5) the ALC Board. The RF
output of the board is being used as a driver and has a level of 3W maximum 8-VSB. At
this power level the board draws approximately 1.8A total from the power supply.

(A6-A2) RF Module Pallet, Philips, High Output (1309580)
The RF Module Pallet, Philips, High Output, (1309580) is made from the RF Module
Pallet, High Output w/o Transistors (1309579). This broadband amplifier is for the
frequency range of 470 to 860 MHz. The amplifier is capable of delivering a maximum
output power of 100 Watts peak, with an amplification factor of approximately 13 dB.
The amplification circuit consists of push-pull amplifier blocks V1 and V2, connected in
parallel, operating in class AB. In order to match the impedance of the transistors to the
characteristic impedance of the input and output sides, matching networks are placed
ahead and behind the amplifier blocks. Transformers Z3 and Z4 at the input to V1 and
V2 and Z5 and Z6 at the output of V1 and V2 serve to balance the input and output
signals. The paralleling circuit is achieved using the 3-dB input coupler Z1 and the
second part of Z1, which is the 3-dB output coupler. The working point settings of the
amplifier circuits are factory implemented by means of the potentiometers R11 and R12
and should not be altered. The combined output of Z1 connects to the RF output jack of
the board at J2. The output of the amplifier assembly at J2 connects to J1 on (A7) the
output detector board.

The bias voltage for the transistor is generated from +48VDC that connects through the
resistor R3 to the drain on Q1 and through the voltage regulator U1. The regulated
voltage at the output of U1 is adjusted with the pots R7 and R6 before it is connected to
the drain on Q1. The Diode CR1 provides temperature compensation for the transistor.
The transistor is capable of producing an output of over 20 Watts ATSC. The amplified
output is connected thru a matching network to one input of U4 a hybrid combiner.
The other output of the input splitter is fed thru an identical amplifier circuit as described
for the Q1 transistor, except it is for the Q2 transistor. C45 is adjustable for best
response, R16 and R17 are the bias adjustment pots and CR2 is the temperature
compensating diode for the Q2 amplifier circuit. The amplified output of Q2 is connected
thru a matching network to the other input of the U4 hybrid combiner. The hybrid
combiner combines the two amplified outputs of the Q1 and Q2 LDMOS devices and
produces a single RF output (≈+42dBm) of the board and the assembly, which a cabled

(A6) Amplifier Assembly (1312191) – Used in CU0TD/RD-4 & CU0TD/RD-5
The (A6) Amplifier Assembly (1312191) is made up of (A6-A1) the 1 Watt Amplifier
Board (1310282), (A6-A2) the BL871 Single Stage Amplifier Board (1311041), and (A6-
A3) the Dual 878 Pallet Assembly (1313170 or 1310138). The ALC Board (1315006) is
also used with this assembly. The entire amplifier assembly has approximately 36 dB of
gain.
(A6-A1) 1 Watt UHF Amplifier Module (1310282)
This board is a broadband UHF amplifier capable of producing an output power in excess
of 1W Peak. It is normally operated at an average power of 100 mW 8VSB or lower. It
consists of two AH202 MMICs operating in parallel. The board is powered by +12 VDC
and has no adjustments. The board has a gain of approximately 16 dB.
(A6-A2) BL871 Single Stage Amplifier Board (1311041)
This board consists of a single stage amplifier operating at +42 VDC. The board has an
overall gain of about 16 dB. The input to the board passes through a 3 dB attenuator
consisting of R11-R13, and then is applied to the gain stage, which consists of a single
LDMOS transistor Q1 operating in Class AB. The bias voltage for the transistor is
generated through the voltage regulator U1, and is adjusted using pots R2 and R3. The
Diode CR1 provides temperature compensation for the transistor. The transistor will
output over 20 Watts DVB, but is typically used in a driver application at much lower
output powers. The Directional Coupler U1 provides a 20 dB down sample of the RF
output.
(A6-A3) Dual 878 Pallet Assembly (1313170 or 1310138)
This board is a LDMOS UHF power amplifier consisting of two power transistors
operating in parallel. The board operates on a power supply voltage of +42 VDC. The
voltage regulator U1 steps down the voltage to provide a bias voltage to each transistor.
The diodes CR1 and CR3 are used to temperature compensate the bias voltage. As the
RF transistors heat up, the diodes also heat up, causing the voltage across them to drop,
lowering the bias voltage to the RF transistors so that it remains constant with device
temperature.

The board has a gain of approximately 17 dB, and can operate at an output power of
150 Watts average power DVB, 220 Watts average power ATSC, or 440 Watts Peak Sync
plus sound in analog operation. The transistors are operated in quadrature, with one
transistor operating 90 degrees out of phase of the other, which provides for a very
good return loss across the UHF band on both the input and output of the board.
(A6) Amplifier Assembly 1316035– Used in CU0TD/RD-4 & CU0TD/RD-5
The (A6) Amplifier Assembly (1316035) is made up of (A6-A1) the 1 Watt Amplifier
Board (1310282), (A6-A2) the BL881 Single Stage Amplifier Board (1314882, and (A6-

This board consists of a single stage amplifier operating at +48 VDC. The board has an
overall gain of about 16 dB. The input to the board passes through a 3 dB attenuator
consisting of R11-R13, and then is applied to the gain stage, which consists of a single
LDMOS transistor Q1 operating in Class AB. The bias voltage for the transistor is
generated through the voltage regulator U1, and is adjusted using pots R2 and R3. The
Diode CR1 provides temperature compensation for the transistor. The transistor will
output over 40 Watts pk sync, but is typically used in a driver application at much lower
output powers. The Directional Coupler U2 provides a 20 dB down sample of the RF
output at the SMA Jack J4.
(A6-A3) Dual BLF888A Pallet Assembly (1315347)
This board is a UHF LDMOS power amplifier consisting of two pair of power transistors
operating in parallel. The board operates on a power supply voltage of +48VDC. The
voltage regulator U1 steps down the voltage to provide a bias voltage to each pair of
transistors. The diodes CR1 and CR3 are used to temperature compensate the bias
voltage that is applied to the Q1 and Q2 RF transistor pairs. As the transistor pairs heat
up, the diodes also heat up, causing the voltage across them to drop, lowering the bias
voltage to the RF transistors so that the voltage remains constant with device
temperature.
The board has a gain of approximately 18 dB. The RF input to the board is split by HL1
and each output is connected through hybrid couplers to the Q1 and Q2 transistor pairs.
The amplified outputs of the transistor pairs are connected through hybrid couplers to
the combiner HL2.
The transistor pairs are operated in quadrature, with one transistor pair operating 90°
out of phase of the other, which provides for a very good return loss across the UHF
band on both the input and output of the board.

(A7) Output Detector Board (1312207)
The (A7) Output Detector Board provides forward (2V=100%) and reflected (2V=25%)
power samples to the CU Control Board for metering and monitoring purposes. R7 is the
reflected power calibration pot and R23 is the forward power calibration pot. A Forward
power sample, -10 dBm, connects to J4 on the board, which is cabled to the front panel
sample jack of the drawer. The RF output of the board, typically +46 dBm, is at J2,
which is cabled to J9 the RF Output Jack of the drawer. The (1312207) output detector
board can be used as either an average, for digital, or peak, for analog, detector board
using jumpers on J5 and J6.
(A8) Control Card, Innovator CX (1312543)
The Innovator CX control board provides the overall system control for the CX system.
There are two main elements of the board, U7 and U9. U7 is a programmable logic
device that is loaded with firmware, which provides the overall system control. It
decides whether or not to allow the system to generate RF output power, and turns the
+40 VDC power supply on and off depending on whether or not it is receiving any faults,
either faults generated on board, or faults generated externally. The second major
component of the board is the microcontroller U9, which controls the front panel
indications and drives the display. The U9 microcontroller is not involved in the decision
making process, U7 does that. Rather, it is layered on top of U7 and is the EPLD's
interface to the outside world. Information is passed between the microcontroller and
the EPLD. The microcontroller communicates information to and from the front panel
and sends the EPLD the information it needs to decide whether or not to allow the
system to turn on. The front panel viewable LEDs DS3 for Operate/Standby and DS4 for
Status indicate the current operating condition of the system are mounted on and
controlled by this board. The U9 microcontroller can also communicate, using the
Optional Ethernet Kit, with a daughter card that allows the user to view remote control
parameters via a web Ethernet interface.
The ±12 VDC and +5 VDC from the (A9) power supply and the 39-42 VDC from the
(A10) power supply are routed to the other boards in the drawer through this board.
The +40 VDC power supply operates all the time, and connects the 39-42 VDC to the
board at J19-1, 2, & 3 with 5 common. Q13 on the control board is turned on and off to
gate the 39-42 VDC, which connects through J19-6, 7 & 8, to the RF output stages.
The ±12 VDC and +5 VDC input voltages to this board is connected through J21 and
filtered before being connected to the rest of the board. +12 VDC connects through
J21-1, +5VDC through J21-2 & 3, and -12 VDC through J21-6. Common connections for
the input voltages are connected to J21-4 & 5. The ±12 VDC and +5 VDC are used on
this board and also routed to the other boards in the drawer through this board. The
+3.3 VDC for the microcontroller and programmable logic array, mounted on the board,
is provided by the voltage regulator IC U6 from the filtered +5 VDC input. The output of
U6 can be adjusted to +3.3 VDC using R120.

Voltages
Voltages for the operation of the boards in the drawer are generated by (A9) a +5VDC
and ±12VDC power supply and (A10) a switching power supply which is a different
power supply providing a different voltage in each model. See the chart above. The
115VAC or 230VAC input to the CU0TD/RD-1 thru CU0TD/RD-3 drawer connects through
the AC power cord at J6, the power entry module located on the rear panel of the
drawer.
The CU0TD/RD-4 & CU0TD/RD-5 drawer only operates with 230VAC. An On/Off
10A/250VAC circuit breaker is part of the power entry module. With the circuit breaker
switched On, the (L) line input is wired to F1 a 10 Amp fuse for over current protection.
The AC lines are connected to terminal block TB1, which distributes the AC to (A9 and
A10) the two DC power supplies. There are two varistors, mounted on TB1, connected
from the line input to neutral and to ground for surge protection. The AC in the
CU0TD/RD-4 & CU0TD/RD-5 also connects to the (A11) fan mounted on the rear panel
of the drawer. The fan will run when AC is applied to the drawer and the circuit breaker
is switched On. The +5VDC and ±12VDC outputs of the (A9) power supply connects to
the terminal block (TB2) that distributes the DC to the boards in the drawer. Some of
the +5VDC and ±12VDC outputs connect directly to the 8 VSB Demodulator and 8 VSB
Modulator
The +28/+42/+48VDC outputs of the (A10) power supply connect to the (A8) CX
Control Board, which then supplies the switched +28/+42/+48VDC VDC to the (A6)
Amplifier Assembly. In CU0TD/RD-1 thru CU0TD/RD-3 drawers the DC output of the
(A10) power supply also connects to the (A11) fan mounted on the rear panel, which will
operate when AC is applied to the drawer, the On/Off circuit breaker is On and the (A10)

The Amplifier Control Board uses a Programmable logic device, U12, to control the
amplifier drawer. It takes an enable signal from an external driver drawer, and turns the
power supplies on whenever the driver has told it to turn on, unless it detects faults
internal to the drawer. The board monitors the forward and reflected power, the heatsink
temperature, the pallet currents, and the power supply voltage and will generate alarm
signals if any of those parameters exceed safe limits. The amplifier drawer has no front
panel display other than a two LEDs, one for Status and one for Enable. The board sends
all its output information, including the forward and reflected levels, back to the driver
drawer, through J4, so the information can be displayed on that drawer's LCD Display.
The board will generate a Red Blinking Status LED if it detects an alarm, fault, prompting
the operator to look at the LCD display on the driver drawer to see what fault has
occurred.
A CUB transmitter System can have up to 4 external amplifier drawers and since they are
all the same, without differences in the wiring harness, there needs to be a way to identify
which amplifier drawer is which. The rotary switch SW1 is used to specify the amplifier ID
number which generates a unique serial address so that the individual amplifier drawers
will respond when polled for information.
The +5 VDC inputs to this board are routed through J4-8 and J5-8. The +5 VDC inputs
are diode Or connected so that either the +5VDC from the (A8) power supply or the
+5VDC from the (A9) power supply will operate the board. The +5VDC is split with one
output connected to U1 a voltage regulator IC, which provides +5V and +5V_ANALOG as
outputs. The +5 VDC is filtered before being connected to the rest of the board. The
other +5 VDC output is connected to the regulator IC U2 that supplies +3.3 V to the
microcontroller and programmable logic array.
(A10) Current Metering Board (1309130)
The current metering board measures the current into the RF output amplifier pallets
and supplies this value to the control board. In the single pallet amplifier drawer, there
are two sensing circuits which are used. In the multiple pallet amplifier drawer, there
are four sensing circuits which are used. Each circuit has two parallel .01Ω series
current sensing resistors and a differential input IC that supplies a voltage output that is
proportional to the current for metering purposes. The +42VDC from the (A8) power
supply connects to TB2 and TB4 on the board. The +42VDC from the (A9) power supply
connects to TB8 and TB10 on the board. The +42VDC input at the TB2 input senses the
current to the (A1) 878 output amplifier pallet through TB1 on the board. The +42VDC
input at the TB4 input senses the current to the (A2) 878 output amplifier pallet through
TB3 on the board. The +42VDC input at the TB8 input senses the current to the (A3)
878 output amplifier pallet through TB7 on the board. The +42VDC input at the TB10
input senses the current to the (A4) 878 output amplifier pallet through TB9 on the
board.
The two or four sensing circuits are identical therefore only one will be described. For
the (A1) 878 amplifier pallet, the +42VDC from the (A8) switching power supply
connects to TB2. R1 and R2 are the parallel .01Ω current sensing resistors which
supplies the voltage values to the U1 current sense amplifier IC. R11 is a gain adjust,
which is adjusted to eliminate any rSense Error and to place the OpAmp output at 2.61V
for 40Amps sense as measured at TP3. The current sense output at J1-1 connects to
the (A7) control board for metering purposes.

(A8 & A9) One, two & three pallet Amplifier Drawer Power Supplies
The 230VAC, needed to operate the drawer, connects through the AC power cord at J3,
the power entry module located on the rear panel of the drawer. The AC lines are
connected to a terminal block TB1 to which the circuit breaker(s) connect. In a N+1 one
pallet amplifier drawer and all multiple pallet amplifier drawers, there are two On/Off
20A/250VAC circuit breakers that are mounted on the back panel of the drawer on either
side of J3 the AC input jack. With the circuit breakers switched On, the AC is distributed
to the two (A8 and A9) DC power supplies. In a standard one pallet amplifier drawer
one 20 Amp circuit breaker CB1 connects the AC to the (A8) DC power supply. TB1 has
three varistors (VR1-VR3) connected across the AC input lines for surge and over
voltage protection. The AC input from TB1 also connects to through 2 amp fuses to the
two fans (A11 & A12) mounted in the drawer. Both fans will run immediately when AC
is applied to the drawer.
The +5VDC for the operation of the amplifier control board in the drawer is generated by
the (A8 & A9) power supplies at J1-9 on each power supply. The +5VDC from the (A8)
power supply connects to J4-8 and the +5VDC from the (A9) power supply connects to
J5-8 on the control board. The +5VDC is produced when AC is connected to the drawer
and the CB1 and/or the CB2 circuit breakers are turned On. Either or both power
supplies provides the +5VDC for use by the control board.
The +48VDC needed by the amplifier modules on the heatsink assembly is generated by

Amplifier
(A5) System Metering Board (1312666)
Note: The external System Metering Board is only used in Transmitters with multiple
external Amplifier Drawers.
The function of the System Metering Board is to detect forward and reflected output power
samples and generate output voltages that are proportional to the power levels of the
sampled signals for use by the control monitoring assembly in the exciter/driver drawer.
There are two identical signal paths on the board: one for forward power and one for
reflected power. A sample of the forward output power, from the external (A11) output
coupler, enters the board at the SMA jack J3. The signal is filtered and connected to
resistors R5, R3 and R6 that form an input impedance-matching network to Pin 3 on U1.
The forward power signal is detected by the RF detector IC U1. The detected output at
pin 7 is split with one half connected to the forward average calibration pot R7, digital,
which adjusts the level of the signal connected to Pin 11 on U2.

Instruction Manual, Rev. 2 120
The other half of the split is connected to the peak calibration pot R18, analog, which
adjusts the level of the signal connected to Pin 8 on U2. U2 is a Bilateral Switch IC whose
output, digital or analog, is controlled by the selection of the modulation type in the
exciter/driver drawer. In this BTC transmitter the average, digital, output connects to the
amplifier IC U3A that is wired to the SYS_FWD and RMT_FWD Power Metering Outputs. A
reading of 2 VDC measured at TP1 is equal to a 100% Forward Power reading on the
meter. The SYS_FWD level connects to J9 on the board that is cabled to J11 on the
exciter/driver drawer for use in the control monitoring assembly. The RMT_FWD level
connects to J10 on the board for use by remote control and monitoring.
A sample of the reflected output power, from the external (A11) output coupler, enters
the board at the SMA jack J8. The signal is filtered and connected to resistors R26, R22
and R27 that form an input impedance-matching network to Pin 3 on U6. The reflected
power signal is detected by the RF detector IC U6. The detected output at pin 7 is
connected to the reflected calibration pot R25, which adjusts the level of the signal
connected to the amplifier IC U3B that is wired to the SYS_RFLD and RMT_RFLD Power
Metering Outputs. A reading of 2 VDC measured at TP2 is equal to a 25% Reflected
Power reading on the meter. The SYS_RFLD level connects to J9 on the board that is
cabled to J11 on the exciter/driver drawer for use in the control monitoring assembly. The
RMT_RFLD level connects to J10 on the board for use by remote control and monitoring.
+12 VDC enters the board at J9-1, from the exciter/driver drawer and is connected
through a filter and isolation circuit consisting of C31, C14 and L5 before it is connected to
the regulator IC U5. U5 supplies the +5 VDC needed for operation of the ICs on the
board. The +5 VDC is connected through a filter circuit consisting of C15, C19 and C21
before it is connected to the rest of the board.
(Optional) ASI to S310 Converter Module
NOTE: The ASI to S310 Converter Modules is only used with STL ASI feed inputs.
The ASI to SMPTE 310M converter takes the STL ASI feed input, if present in your system,
and converts it to a SMPTE 310M output which connects to the input to the UBS-Axcera
system. The converter contains an ASI Motherboard (1311179), an ASI to 310
Conversion Board, Non-SFN (1311219) or ASI to 310 Conversion Board, SFN (1309764),
and a 120 VAC to +12 VDC converter module.
ASI Motherboard (1311179)
The ASI motherboard takes the +12 VDC, from the 120 VAC to 12 VDC converter
module, and converts it to +5 VDC and +3.3 VDC which are used by the ASI to S310
conversion board.
U1 is a regulator IC that supplies an output of +5 VDC at J2-7 that connects to the ASI
to 310 converter board. U2 is a regulator IC that supplies an output of +3.3 VDC at J2-
11 that connects to the ASI to 310 converter board. Also +12 VDC is wired to J2-3 that
connects to the ASI to 310 converter board.
The ASI motherboard is the mounting platform for the four LEDs that are displayed on
the front of the module. The LEDs will be Green if everything is OK or Red if the
indicated function is malfunctioning.

which indicates the recovered ASI signal is in a locked condition.
ASI to 310 Conversion Board, Non-SFN (1311219)
The ASI signal is input to the ASI to S310 conversion board via J1. U2 de-serializes the
ASI input signal into a parallel byte stream. The parallel byte stream is clocked into U6
which buffers and converts it to a valid S310 bi-phase encoded signal. Null packets are
added or dropped during this process to obtain the valid 19.393 Mb/s output. U6 is also
responsible for re-stamping the PCR clock. The final S310 output of the board is at J5.
ASI to 310 Conversion Board, SFN (1309764)
The ASI signal is input to the ASI to S310 conversion board via J1. U2 de-serializes the
ASI input signal into a parallel byte stream. The parallel byte stream is clocked into U6
which buffers and converts it to a valid S310 bi-phase encoded signal. For SFN
operation the ASI payload must be 19.392568 Mb/s +/- 2 ppm. A 38.785317 MHz
VCXO locks to the exact S310 bit-rate using a Digital PLL. This method ensures the
extracted S310 stream is frequency locked without modifying its content i.e. add/drop
null packets, PCR restamp, etc. The final S310 output of the board is at J5.

ALC Board Set-Up - Forward and Reflected Power Calibration
NOTE: If your system is a CU1TD/RD-1 or higher power with one or more external
amplifier drawers, refer to the next section for the forward and reflected power
calibration procedures.
The steps for calibrating the forward and reflected power using the ALC board are as
follows:
1. Locate (A4) the ALC Board (1315006).
2. Set the Overdrive Threshold potentiometer (R38) fully CW.
3. Set the Manual Adjust potentiometer (R62) fully CCW.
4. Set the ALC Adjust potentiometer(R75) fully CCW.
5. Switch S1 to Manual Gain.
6. Increase the output power to 100% using R62.
7. Calibrate the system output power for 100% using the Forward Calibration
potentiometer (R23) on the Output Detector Board - Refer to Figure 63.
8. Turn the output power down to 10% power using R62 on the ALC Board.
9. Remove the RF output connector from J2 on the drawer.
10. Calibrate the reflected power to 10%, using the Reflected Calibration
potentiometer (R7) on the Output Detector Board - refer to Figure 63.
11. Re-connect the RF output connector to the drawer.
12. Increase the power, in Manual gain mode, to 115% using R62 on the ALC Board.
13. Adjust the Overdrive pot (R38) on the ALC Board, CCW until the overdrive
threshold just trips and the Overdrive Fault LED DS4 lights.
14. Turn R38 slightly CW so that power comes back up and DS4 goes out.
15. Switch S1 on the ALC Board to ALC.
16. Turn the ALC Adjust potentiometer (R75) on the ALC Board until the power is
100%.
17. Switch S1 between ALC and Manual to verify smooth switching, with minimal
change in power. If necessary repeat the above procedure.
18. With the drawer in ALC, use the ALC Adjust potentiometer (R75) to decrease the
power to 10%.
19. Remove the RF output connector from the drawer.

20. Verify that the VSWR Cutback LED, DS6, comes on and the Reflected Power
drops to approximately 6%.
21. Reconnect the RF output connector and increase the power back up to 100%
using R75.
This completes the set up of the ALC board and the Forward and Reflected Power
Calibration.

Forward and Reflected Power Calibration of a Higher Power System
NOTE: If your system is a CU0TD/RD-1 thru CU0TD/RD-5, refer to the previous section
for the forward and reflected power calibration procedures.
Forward Power Calibration
1. Connect a calibrated coupler and average reading power meter to the output of
the DTV mask filter.
2. On the ALC Board (1315006), mounted in the Driver Drawer, set the Switch S1,
Auto/Manual ALC, to the Manual position - refer to Figure 64.
3. Adjust the Manual adjustment Pot (R62) for the desired output power level as
indicated on the average reading power meter.
4. In the Amplifier Drawer, on the Amplifier Control Board (1309822), adjust the
Forward Calibration Adjustment potentiometer (R8), for a reading of 100% on
the External Amplifier Forward Power screen, which can be viewed on the CX
drawer LCD.
5. On the ALC Board (1315006), mounted in the Driver Drawer, set the Switch S1,
Auto/Manual ALC, to the Auto position.
6. Adjust the ALC adjustment Pot (R75) for a reading of 100% on the External
Amplifier Forward Power screen, which can be viewed on the CX drawer LCD.
This completes the reflected power calibration adjustment.
Reflected Power Calibration
1. On the ALC Board (1315006), mounted in the Driver Drawer, adjust the ALC
adjustment potentiometer (R75) for a reading of 10% on the External Amplifier
Forward Power screen, which can be viewed on the CX drawer LCD.
2. Disconnect the load or the antenna connected to the system.
3. In the Amplifier Drawer, on the Amplifier Control Board (1309822), adjust the
Reflected Calibration Adjustment potentiometer (R26) for a reading of 10% on
the External Amplifier Reflected Forward Power screen, which can be viewed on
the CX drawer LCD.
4. Reconnect the load or the antenna to the system.
5. Adjust the ALC adjustment potentiometer (R75) for a reading of 100% on the
External Amplifier Forward Power screen, which can be viewed on the CX drawer
LCD. This completes the reflected power calibration adjustment.
