General
Description
This section contains a general description of the Maxiva UAX ‐ C Series of television transmitters.
Included in this section will be descriptions of the control system, amplifier, block diagrams of the various models and system specifications.
The UAX ‐ C series of solid state, air cooled transmitters is designed to synthesize and amplify radio ‐ frequency signals in the UHF broadcast bands IV & V (470 to 862 MHz).
All UAX ‐ C models contain the following major sub ‐ assemblies: control panel, exciter, controller, and amplifier, as shown in Figures 1 ‐ 1, 1 ‐ 2 & 1 ‐ 3.
The UAX ‐ C chassis top cover may be removed to provide access to internal circuit boards once AC mains power has been disconnected for personnel safety.
All interconnections are via the rear panel, with the exception of a front Ethernet port for diagnostic use.
The UAX ‐ C contains two axial fans mounted in the right and left sides of the chassis front.
Cooling air is drawn into the assemblies from the front and forced over the top and bottom sides of the circuit boards, and exits from the rear of the UAX ‐ C exciter section.
The left fan cools the exciter part of the unit and the right fan cools the PA section.
The fans are not redundant.

1.5.1
Signal Chain
The UAX ‐ C receives the program material to be transmitted in the form of a digital transport stream via rear panel
BNC connectors and generates a low ‐ level on ‐ channel intermediate frequency (IF) signal in the signal processing board.
The signal processing board also predistorts the signal to compensate for non ‐ linear distortions occurring in the transmitter RF power amplifier and for linear distortions/group delay occurring in the output channel filter external to the transmitter.
This precorrection system is commonly known by its abbreviated name: RTAC™ (Real
Time Adaptive Correction)
The low ‐ level IF signal from the signal processing board is passed to the UHF up/down converter board, where it is translated to the final UHF channel frequency.
The up/down converter has an internal variable gain adjustment, which is used by the control system to maintain automatic RF level control at the transmitter output.
In addition to up converting the outgoing RF signal, the up/down converter board also down converts incoming RF samples taken from the transmitter output for use by the RTAC precorrection system.
The on ‐ channel RF output from the UHF up/down converter is applied to the power amplifier module (PA).
The PA utilizes a FET ‐ based broadband amplifier design to amplify the RF signal to the final desired power level.
In addition to RF drive power from the upconverter stage, the PA module utilizes 50V DC supplied by a switch mode AC/DC converter (power supply) module.
The PA module itself operates in open loop mode (no gain or level adjustment).
The transmitter RF output power level is adjusted via the variable gain circuit located in the UHF up/down converter.
Final RF output is via a type N connector.
The local oscillators required for proper system operation are provided by the precise frequency reference unit
(PFRU).
The UAX ‐ C can accept a 10 MHz external frequency standard input or a 1PPS (pulse per second) input via rear ‐ panel BNC connectors.
An SMA (female) GPS antenna input is also available.
An external standard is used whenever the user requires increased frequency precision, or a precise frequency offset.
The 1PPS or GPS input are typically used for single frequency network (SFN) operation.

Control System
The UAX ‐ C system control is provided by the microprocessor daughter board which is mounted on the signal processing board, as shown in Figure 1 ‐ 2 on page 1 ‐ 3.
The transmitter is shipped from the factory with software preloaded and ready to run.
Should a software update be required, it can be easily updated using the web browser and In System Programming (ISP) programming utility.
See
3.4.1
for further details.
The UAX ‐ C transmitter has an LCD display and control buttons on the front panel to allow the user to locally control the transmitter as shown in Figure 1 ‐ 1 on page 1 ‐ 3.
The LCD panel and pushbuttons provide limited control of the transmitter system.
More advanced tasks, such as changing the feature key and modulation settings, must be performed via the web browser interface.
1.5.3
Remote Control
The UAX ‐ C transmitter has a wired parallel remote control located on the customer I/O card at the rear panel.
Detailed information on the remote control connections to the UAX ‐ C can be found in Section 2.7.
A remote web GUI interface provides comprehensive control and monitoring of data points within the transmitter.
It includes an SNMP (simple network management protocol) agent which allows integration with most control systems via the Internet or LAN.
There are two RJ45 Ethernet connectors.
One Ethernet connector is located on the front control panel.
This connector has a static IP address and acts as a DHCP server.
The other RJ45 Ethernet connector is on the rear of the unit and can be configured as a DHCP client or assigned a static network IP.
1.6
Operating
Voltages
All UAX ‐ C model transmitters require the following AC mains connection:
Single phase, 110 to 240 V AC (auto ‐ ranging), ‐ 15% to +10%, 47 to 63 Hz, one IEC C15 inlet.
Caution
CHECK THE AC POWER FEEDING THE UAX-C. IT MUST BE BETWEEN 110
VAC AND 240 VAC. ANY VOLTAGE OUTSIDE THAT RANGE WILL CAUSE
DAMAGE TO THE EQUIPMENT. THE VOLTAGE SHOULD BE MEASURED LINE
TO LINE, OR WHEN A NEUTRAL IS USED, LINE TO NEUTRAL.
Caution
IF VOLTAGE VARIATIONS IN EXCESS OF ±10% ARE ANTICIPATED, THE
TRANSMITTER POWER INPUT MUST BE EQUIPPED WITH AUTOMATIC
VOLTAGE REGULATORS (OPTIONAL EQUIPMENT) CAPABLE OF
CORRECTING THE MAINS VOLTAGE.
1.7
Transmitter
Accessories
The UAX ‐ C chassis contains the basic UAX transmitter.
Additional options are available and may be present in a UAX ‐
C transmitter system.
In as much as these accessories do not significantly change the functioning of the core transmitter itself, it is understood that this manual addresses customized transmitter configurations that may contain one or more of these options.
In the case of a relatively high level of customization, this manual may also be accompanied by a supplemental
“customer ‐ special” manual.
In the case where conflicting information is presented in the two manuals, the information given by the customer ‐ special manual supersedes any information contained in this manual.

Installation
Note
This equipment is intended only for installation in a RESTRICTED ACCESS LOCATION.
Steps in the installation section are numbered in each section.
As each step is completed, the step number can be circled to indicate completion.
This provides a quick confidence check at the end of the procedure that no steps were skipped.
Note
In case of discrepancy between the connections listed in diagrams versus information given in this installation section, the wiring information in the diagrams should be considered the most accurate. All connections listed in this section should be verified with the schematics before initial turn on.
When performing the installation, after the transmitter is in place, plan to run the transmitter output transmission lines first, then the air cooling system components (if ducting is used), and finally the electrical conduit runs.
Note
If air handling duct work is to be installed, plan all of the RF and conduit runs to leave room for the duct work.
The reason for this installation order is that rigid coax runs need to be installed using a minimum number of elbows to obtain the maximum level of performance at the lowest possible cost.
Installation of RF lines is more complicated if obstacles like conduit, and ductwork are in place.
Note
RF coaxial lines must be properly supported.
2.5.1
Transmitter Placement & Operating Environment
The selection of a proper installation location is essential for equipment longevity and reliability.
Do not install the transmitter in places where it may be exposed to mechanical shocks, excessive vibration, dust, water, or acidic gas.
Ambient temperature and relative humidity should always range between the following limits at the installation location:
•
Ambient temperature: 0 to +45 o
C.
(0 to +40 o
C.
for UL 60950)
•
Relative humidity: 0 to 90% non ‐ condensing
Note
Failure to follow these installation instructions may void the warranty.
The transmitter should be placed where it will have adequate room to access the front and rear panels.
There are several drawings included in the drawing package to help plan the transmitter placement:
STEP 1
Open the box and remove the packing material that surrounds the transmitter.
STEP 2
Place the transmitter in position.
2.5.2
Rack Mounting Components
In many instances, UAX ‐ C transmitter components will ship without a mounting rack.
The transmitter may be installed in customer supplied equipment racks.
In these instances, it is the customer’s responsibility to properly support and mount the equipment in the racks.
Equipment installed in racks must be properly installed on shelves or use brackets that safely and adequately support the weight of the equipment.

Transmitter
AC
and
Ground
Connections
Note
AC connections will be similar for all UAX-C transmitter models. Be sure to verify all connections using the correct schematic drawings.
The UAX ‐ C does not have an AC mains on/off switch.
Power is applied to the unit by plugging an energized power cord into the AC mains inlet (IEC C15) on the back of the unit.
All UAX ‐ C power levels will operate over a voltage range of 110 ‐ 240VAC, 47 ‐ 63 Hz.
The power supplies internal to the UAX ‐ C are auto ‐ ranging; no adjustments or circuit changes are required when changing the applied AC mains voltage (e.g.
a change from 120V to 230V operation ),
2.6.1
Surge Suppression Devices
Harris Broadcast strongly recommends the use of surge protection devices on the incoming AC mains lines.
These devices protect against damages due to transients arising from both natural and man ‐ made sources.
(e.g.
lightning and inductive load switching).
Clear preference is to be given to “series” type surge protection devices ‐‐ featuring protection by both a series inductance / shunt capacitor filter and shunt threshold device ‐‐ over simple shunt ‐ only clamping devices.
The surge protector must be sized to handle the full amperage of the load it is protecting (plus a nominal safety margin) and be connected to the building ground system by short, direct connections.
In the case where the shunt protection elements are protected by a fuse, it is necessary to periodically check the integrity of the fuse to ensure continued transient protection.
2.6.2
Voltage Regulation
If AC mains voltage variations in excess of ‐ 15% to +10% are anticipated, the transmitter power input must be equipped with automatic voltage regulators (optional equipment) capable of correcting the incoming mains voltage.
2.6.3
Safety Ground
The UAX ‐ C stand ‐ alone transmitter is equipped with a safety ground lug connection on the rear panel just below the
AC connection (see
This safety ground should be connected to the site ground system.

Cooling
System
The UAX ‐ C contains two 12V fans in the front of the unit.
The front panel contains washable filter material which should be in place when the unit is operating.
The front panel can be removed for maintenance while the transmitter is operating but the panel should be in place during normal operation.
The 12V DC fans can be changed while the transmitter is operating.
See
for replacement instructions.
Note
Prior to start-up, the cooling fans should be visually checked to make sure there are no obstructions.
Job site environmental conditions should be evaluated periodically to assure filter cleanliness.
Schedule maintenance activities to accommodate changing environmental conditions at the site.
See
for instructions on cleaning filters.
Note
Special note concerning stand alone units: Rack selection is key to maintaining proper cooling of stand alone units. To provide proper cooling, a rack with ample venting through the front and rear doors should e selected to ensure proper air flow from the front and rear of the rack.

RF
Connections
2.10.1
RF Output
Prior to operation the transmitter RF output connector must be connected to a known good test load or antenna with a high quality 50 ohm RF cable.
A patch panel may also be used if switching between load and antenna is desired.
A type N male connector is needed for the transmitter output side of the cable.
The UAX ‐ C output connection is located on the rear panel see
Section Figure 2 ‐ 6” on page 2 ‐ 10.
The connector needed for the load, filter or antenna end of the cable may vary depending on the customer’s system.
Initial testing into a 50 ohm test load is recommended.
VSWR (voltage standing wave ratio) of the test load should be <1.05:1, antenna system <1.2:1, and filter <1.1:1.
The UAX ‐ C will operate into a VSWR of 1.5:1 maximum but a lower system VSWR is recommended for reliable operation.

2.10.2
RF Sample Connections and Level
An RTAC post ‐ filter RF feedback signal is required for RTAC to perform linear precorrection.
If the unit is running in
RTAC stored mode, this post ‐ filter sample is not required.
The RF sample input connector is located on the UAX ‐ C rear panel and shown in
The feedback sample is taken from the directional coupler located after the system mask filter.
If no mask filter is used or required then the feedback should be via a coupler at the output of the system.
The coupler can be ordered from Harris Broadcast as an option.
If the transmitter system is a 1+1 (main/standby) configuration, feedback samples for each transmitter are obtained by splitting the post filter sample cable.
With the transmitter operating at full TPO the post ‐ filter RTAC sample signals at the UAX ‐ C input should be adjusted with coaxial attenuators to yield a nominal 0 to ‐ 5 dBm at the highest expected transmitter output power.
The post filter sample input power range is ‐ 20 to +5 dBm.

Transmitter
Power
Up
The UAX ‐ C transmitter is now ready to produce RF power; the critical setup steps have been performed.
Some additional setup may be required to setup transport stream handling, set RTAC states, system references, etc., but these will not prevent the unit from making RF power for the time being.
If valid transport streams are not present at the transmitter input, RF output may be inhibited for DVB ‐ T systems.
In that case, the user must connect to the transmitter with a PC and web browser in order to activate the PRBS test mode in the modulation setup pages.
Most other modulation types do not require a valid TS to produce output as long as the modulator settings are correct.
One notable exception, as of this printing, is ISDB ‐ Tb.
This procedure does not attempt to describe modulator settings (web browser setup screens) that need to be set for the various modulation types.
For more detailed setup instructions refer to section three of this technical manual
The initial transmitter power up is as follows:
STEP 1
Refer to information provided above to confirm that grounding, AC mains power, signal inputs, load or antenna hook ‐ up and initial setup steps have been performed.

Explanation
Set the minimum forward power in watts (W) below which a warning is indicated.
If the transmitter output power drops below this level, the forward power bar and Output LED will turn yellow.
This value must be lower than Nominal power.
Set the minimum forward power in watts (W) below which a fault is indicated.
If the transmitter output power drops below this level, the forward power bar and Output LED will turn red.
This value must be lower or equal to the FWD Low PWR Warning.
Set the maximum forward power in watts (W) above which a fault is indicated.
If the transmitter output power exceeds this level, the forward power bar will turn Red.
This value must be larger than the Nominal Power Output.
This entry sets the maximum level that the Fwd Power Reference can be set to in watts (W), and also sets the 100% forward power bar level.
This field represents the actual power setting in the transmitter.
The actual power setting can be reduced from the Fwd Power Reference setting due to any of the following reasons:
‐ The value of the % of Fwd Pwr Reference setting is less than 100%.
‐ Faulted PA components have reduced the maximum output power of the system below the Fwd
Pwr Reference setting.
‐ Transmitter is in power foldback state due to a high level of reflected power at the transmitter output.
Set the percentage of actual transmitter output power.
(valid range 0 ‐ 100%) If the Fwd Power
Reference = 1000W, and the % of Fwd Pwr Reference = 75%, then the actual forward power reference will be 750W.
Set the desired forward power of the transmitter in watts (W).
The Fwd Power Reference setting is limited by the Nominal Power Output setting, thus the valid range for this control is 0 ‐ Nominal
Power Output (W).
This is the level of reflected power in watts (W) that if exceeded will activate power foldback.
(This is a status only field).
Percentage that System Output Power is currently being folded back due to presence of high reflected power conditions.
This level represents the percentage of reflected power that can be tolerated before initiating foldback.
The level can be set from 1 to 4%.
Four percent is the maximum reflected power setting allowed (approximately 1.5:1 VSWR).
A reflected power level of 1% corresponds to a 1.22:1
VSWR.
A system foldback threshold setting of 4% means that reflected levels greater than 4% would initiate a foldback of transmitter output power.
This is the maximum amount of foldback allowed.
Maximum Foldback can be set between 50 and 100%.
Power foldback occurs when the Foldback Threshold, described above, is reached or surpassed.
Foldback allows the transmitter power amplifier(s) to operate at a safe (reduced) output power level when high VSWR conditions occur.
A 100% foldback level means the power out of the transmitter would be zero.
A 50% foldback level would reduce the transmitter output power to half power.
This is the amount of time, in seconds, that the control system waits after foldback is activated before attempting an output power increase step.
The range is 5 ‐ 120 seconds.

Explanation
Factory Fwd/Rfld calibrates the system forward and reflected power meter.
Factory calibration is used as a reference calibration across the UHF band.
The factory forward calibration is performed at 665 MHz (center of
UHF band).
This is a two point calibration process that saves calibration points at a low calibration point
(approximately 10dB down from the transmitter model power) and a high calibration point (transmitter model power).
The Field Fwd/Rfld calibration is used as an additional correction to the factory calibrations.
This is useful when the factory forward calibration is being used as a reference calibration, and the user wants to “touch up” the system forward power meter upon a change in frequency or permanent power level (e.g.
upon installation if licensed TPO is significantly less than transmitter nameplate power rating).
The field calibration process is a one point calibration (at the current FWD POWER REFERENCE setting).
This also allows the user to perform the field calibration without changing the current output power level of the transmitter.
The Start Cal soft button turns Green to indicate that calibration is active, and the adjust output power window appears to walk the user through the low and high calibration points.
System Calibration is discussed in depth in
Section
"Power Calibrations".
Refer to that section for the complete procedure
Once the user has completed all desired calibrations, the Cal Complete button MUST be pressed to return the system to previous mode of operations.This
will allow the system to resume Auto power control mode.
If the user does not press the Cal Complete button the system will remain in Manual power control mode until navigating away from the Cal screen.

RTAC Operating Modes During Power Up: When the UAX ‐ C is powered down, RTAC correction for the Adapt and Hold modes is lost, but the stored RTAC corrections are not lost.
At power up, the transmitter must operate uncorrected for a few minutes while RTAC adapts.
If RTAC power on mode is set to Stored, and if an appropriate correction setup has been previously stored in memory, the Stored correction will be loaded into the RTAC Adapt and Hold circuits.
This correction will then become available for the RTAC off air Hold mode or for the Adapt mode if the unit is on the air.

3.4.3.1
Nonlinear Correction Range Setup
The Nonlinear Correction Range setting provides the ability to proactively clip the modulator signal at a predetermined peak ‐ to ‐ average level in dBs ‐ above ‐ average.
The resulting signal with distortions is then bandpass filtered to reduce the intermodulation products falling into adjacent channels.
This has the result of preemptively lowering the peak ‐ to ‐ average ratio that must be amplified by the subsequent power amplifier stages, but without a corresponding increase in adjacent channel IMD levels.
In ‐ band intermodulation, however, does increase, causing a corresponding drop in modulation error ratio (MER) or error vector magnitude (EVM).
The action of the nonlinear correction range setup can be summed up by this statement:
"more aggressive nonlinear range settings (lower in dB) reduce the level of adjacent channel intermodulation sidebands generated by the power amplifier stages, but at the expense of degraded MER or EVM performace."
STEP 1
In the ’RTAC’ Setup Screen 1 (
on left
set RTAC Linear and
Non ‐ Linear functions to ’Bypass’.
STEP 2
The RF output should be set to the level required for transmitter operation.
STEP 3
In the RTAC ‘Peak Reduction’ sub window of RTAC Setup Screen 3 (
on left
verify that the Non ‐ Linear Range and Max Crest Factor indicators display
‘Enabled’.
STEP 4
In the RTAC ’Peak Reduction’ sub window start with the Non ‐ Linear Range at the default value.
See
STEP 5
With Both RTAC correctors bypassed, the exciter RF output adjacent channel noise should be 50dB to 55dB below the in band signal level.

3.4.3.2
Max Crest Factor Setup
The Max (Maximum) Crest Factor setting limits the peak to average RF output power ratio (7.8
to 13.0
dB) at the output of the exciter.
This directly limits the transmitter RF output peak to average power ratio with a simple, unfiltered clipping stage.
The crest factor of the transmitted signal is determined by this setting and by the peak compression of the amplifier system.
•
If the limit is set too low, clipping will generate out ‐ of ‐ band intermodulation products in the exciter’s out ‐ put and may affect the performance of the RTAC non ‐ linear correction.
•
If set too high, it could allow nuisance overdrive trips in some transmitter models, because the high amplitude peaks could overdrive the PA modules.
Nuisance overdrive trips can be avoided by setting the Max Crest Factor parameter section of the RTAC Peak
Reduction sub window in RTAC Setup Screen 3,
on left
Nuisance overdrive trips will typically occur within 30 minutes to 1 hour after transmitter operation with RTAC is first started.
If this happens, perform the following:
STEP 1
This setup is performed with the transmitter operating at full power and RTAC Linear and Non ‐ Linear functions set to Adapt.
STEP 2
Start with the Max Crest Factor at the default value.
See
STEP 3
Reduce the Max Crest Factor by 0.2dB.
STEP 4
Wait for one hour to see if further overdrive trips occur.
If they do, reduce by another
0.2dB.
STEP 5
Repeat steps 3 & 4 until overdrive trips cease.
STEP 6
Excessive reduction will affect the linearity correction of the transmitter.
After Max
Crest Factor has been adjusted, observe the adjacent channel response to ensure that it still exceeds the transmitter output signal mask requirements.
STEP 7
End on procedure.
3.4.3.3
RTAC Profiles sub window
Profile Linear:
For linear RTAC correction, BASIC and LONG OFFSET profiles should be tried first.
The rule of thumb here is that more is not necessarily better, so use the first profile that works well.
The equalizer length in time generally increases down the list.
Linear profile choices are:
•
BASIC ‐ This correction should be used for most standard mask filters.
•
SHORT
•
LONG
•
MAX
•
BASIC OFFSET
•
SHORT OFFSET
•
LONG OFFSET ‐ This correction should be used for sharp tuned mask filters, special mask filters, or when a two or more transmitters of different frequencies are being combined into a single output through two or more sharp tuned filters.
•
MAX OFFSET
Profile Nonlinear:
For non ‐ linear RTAC correction, the named profiles should be tried before the numbered profiles.
Most transmitters should use BASIC or BASIC MEMORY.
However, if they do not give satisfactory adjacent channel inter ‐ modulation performance, a higher profile such as HIGH or HIGH MEMORY should be used.
Nonlinear profile choices are:
•
BASIC

This is the throughput delay of the RF signal after it leaves the exciter network delay circuit and travels through the rest of the transmitter, transmission line, and antenna.
It is also known as “TAD”, this is a calculated or estimated number that is incorporated in compliance with the ATSC A/110 Distributed Transmission standard.
The exciter will use this value as part of it's calculation of emission time.
Choices are Enable and Disable.
Enabling this function will disable the 10 MHz signal coming out of the front panel 10 MHz port and replace it with a 77 uS pulse that is coincident with the emission of the Data Field Sync portion of the ATSC signal.
Using this signal along with the 1 PPS signal, one could use an oscilloscope to adjust emission timing between two or more single frequency network sites.
Choices are Enable and Disable.
ATSC's A/110 standard defines a side communication channel, called the field rate side channel (FRSC).
The FRSC may be used to populate certain symbols in the data field sync or communicate other information to the modulator e.g.
configuration changes.
However, information to populate the FRSC must be sent from the upstream Distributed Transmission Adapter or a Mobile DTV multiplexer.
This control governs whether or not the FRSC information is used.
If the upstream adapter is not inserting the FRSC information, set to Disable.

The Guard Interval is the time, between symbol transmissions, when nothing is transmitted.
The guard interval is entered as a fraction, which represents the guard interval time as a fraction of the useful symbol duration.
Total symbol duration is the sum of the useful symbol duration plus the guard interval.
In the 2k mode, useful symbol duration is
224 microseconds and in the 8k mode, useful symbol duration is 896 microseconds.
Choices are variable or constant.
Constant only used with PN595, Variable is used with
PN945 and PN420.
Choices are 4QAM, 16QAM, 32QAM, or 64QAM.
Constellation refers to the size of each RF sub ‐ carrier constellation.
LDPC Rate: Choices are 0.4
(2/5), 0.6, (3/5) or 0.8
(4/5).
The LDPC
Rate provides three rates of forward error correction.
The decimal, or fraction, gives the relative efficiency of the forward error correction by dividing the information bits by the total block length.
For example, block length = 7488 bits, information bits = 3008, therefore: 3008/7488 = 0.4
or 2/5.
This indicates that there are two information bits for every five output bits.
Choices are 240 symbols or 720 symbols.
This is a data convolutional interleaver.
The data is interleaved to a depth of 240 or 720 symbols.

This corresponds to Cell ID in the GB spec so transmitter control via Cell ID is possible upstream via the SIP inserter.
Enabling the DC Test Tone Mode transmits a single tone which is placed at the center of the spectrum.
It is used to measure carrier frequency.
The single tone signal is the same power as the exciter is putting out normally.
With this being the same power level this should not cause any damage to the transmitter.
Disabling the DC Test Tone Mode causes normal transmission to be resumed

Explanation
Choices are MFN (Multiple Frequency Network) or SFN (Single Frequency Network).
Range is 0 to 63.
Equipment ID is assigned by the SFN network administrator and is provided to allow a unique identifier for each transmitter in the SFN cell.
When the equipment ID in the IIP packet matches the local equipment ID, then the IIP Time Offset information is extracted
Choices are Yes or No.
If no is selected, transmitter will be muted if SFN information is missing from the transport stream or SFN delay calculations result in negative delays or delays greater than one second.
If yes is selected, the exciter will output RF which is not properly SFN synchronized.
This allows the transmitter operator to set a delay for the transmitter locally.
Its purpose is to cause the RF output to be delayed additionally by the amount entered.
This is the time delay caused by the transmitter’s high power filter and transmission line as well the
GPS delay caused by its cable length.
Its purpose is to cause the RF output to be released earlier by the amount entered thereby nulling out the above mentioned RF delays.
Renewal Flag is a bit in the IIP packet which, on the transition from 1 to 0, indicates the information in the IIP packet is valid.
The renewal flag counter provides the operator with an indication that the IIP information is being updated on a regular bases.
Note that the Max Delay and IIP Time Offset is only updated when the IIP
Renewal Flag changes from 1 to 0.
On exciter power up, the modulator will wait for an IIP renewal flag transition from 1 to 0, which indicates the IIP packet data is valid.
The IIP Time Offset, in ms, allows the SFN Adapter upstream to send an offset time to individual transmitters in the SFN network.
This allows the SFN network operator to change any of the transmitter delays in the SFN from one central location, the SFN adapter.
This delay is sent from the SFN Adaptor to the modulator.
It indicates the time from the time stamp in the IIP packet to when the head of the multiplexed frame is to be emitted.
Processing Delay, in ms, is the time required for the signal to propagate thru the modulator during the modulation process.
This time omits the delay caused by the time interleaver.
This time in ms is the time required for the transport stream to travel from where the IIP packet is time stamped in the SFN adaptor until the packet is received by the modulator.
Storage time, in ms is the Max Delay plus the local RF Delay, minus the processing Delay, minus the
Local Offset Delay, minus the IIP Offset Delay, minus the Network Delay.
SFN Storage Time is the delay buffer incorporated in the modulator to provide the required delay for SFN operation.

This sets the size of the modulation Fast Fourier Transform (FFT), which in turn sets the number of subcarriers used in the COFDM (Coded Orthogonal Frequency Division Multiplex) signal.
It also selects whether the in ‐ depth interleaver (8k) is enabled in 2k and 4k mode.
Choices are 2k, 2k (8k interlaced), 4k, 4k (8k interlaced), or 8k.
Choices are 1/4, 1/8, 1/16, and 1/32.
The Guard Interval is the time, between symbol transmissions, when nothing is transmitted.
The guard interval is entered as a fraction, which represents the guard interval time as a fraction of the useful symbol duration.
Total symbol duration is the sum of the useful symbol duration plus the guard interval.
In the 2k mode, useful symbol duration is 224 microseconds and in the 8k mode, useful symbol duration is 896 microseconds.
Choices are QPSK (Quadrature Phase Shift Keying), 16 QAM (Quadrature Amplitude Modulation), and 64 QAM.
Constellation refers to the size of each RF sub ‐ carrier constellation.
When using the hierarchical mode, 16 QAM or 64 QAM must be selected.
Choices are Non Hierarchical or Hierarchical.
Non Hierarchical modulation allows transmission of only one data stream, the HP (High Priority) input.
Hierarchical modulation allows transmission of two data streams, the LP (Low Priority) and the HP (High Priority) transport stream inputs.
The
Low Priority stream has a higher data rate which produces a higher quality reproduction, but it is less robust and therefore covers a limited distance.
The High Priority stream has a lower data rate which produces a lower quality reproduction, but it is more robust and therefore covers a greater distance.

Choices are 1/2, 2/3, 3/4, 5/6, and 7/8.
These choices affect the convolutional encoder code rate for the High Priority channel.
It offers a choice between the useful data rate (picture and sound quality) verses signal robustness (distance the signal can be received).
A code rate of 1/2 includes one forward error correction bit and one data bit.
This yields a lower quality signal which can be received at a greater distance.
A code rate of 7/8 includes one forward error correction bit for every seven data bits.
This yields a higher quality signal which can be received at a much shorter distance.
Low Priority Code Rate: Choices are: 1/2, 2/3, 3/4, 5/6, 7/8.
The Low Priority Code Rate is only visible when in Hierarchical mode.
These choices affect the convolutional encoder code rate for the low priority channel.

Explanation
Choices are 1K, 2K, 4K, 8K, 16K, or 32K.
This refers to the number of sub carriers in the RF output bandwidth.
See
Choices are 1/4, 1/8, 1/16, 1/32, 1/128, 19/128, or 19/256.
Choices are PP1, PP2, PP3, PP4, PP5, PP6, PP7, or PP8.
See
Choices are Normal or Extended.
Programming range varies with the FFT size and the guard interval.
The maximum number of data symbols per T2 frame is given in the table below.
An odd number must be entered.
If an even number or a number which is over the limit is entered, the exciter will mute.
A larger number is more data efficient, but it also increases receiver lockup time.
A super ‐ frame is composed of a set of T2 ‐ frames consisting of a particular number of consecutive T2 ‐ frames.
A super ‐ frame may include FEF (future extension frames) parts, two
FEF parts can not be adjacent (must be separated by one or more T2 frames), and if FEFs are used, the super ‐ frame ends with a FEF part.
The maximum time for the super ‐ frame length
(TSF) is 64 seconds if FEFs are not used (equivalent to 255 T2 frames of 250 ms) and 128 seconds if FEFs are used.
The maximum number of T2 frames are independent of the number of FEF parts used.
Presently 5 MHz, 6MHz, 7 MHz, and 8 MHz, in the future 1.7
MHz bandwidth will be added.
Choices are BPSK, QPSK, 16QAM, or 64QAM.
The L1 Mod referred to above gives a choice of the modulation constellation for the P2 symbol(s).
L1 refers to the Layer 1 signalling within the T2 frame.
L1 is split into three main sections: The
P1 signalling, the L1 ‐ pre signalling and L1 ‐ post signalling.
The the L1 ‐ pre and post signalling is carried by the P2 symbol(s), which may also carry data.
Choices are None, ACE, TR, or ACE & TR.PAPR
= peak to average power ratio.
This choice allows two methods of peak to average power ratio reduction.
TR = Tone Reservation
ACE = Active constellation extension, The active constellation extension technique should not be applied when rotated constellations are used or when MISO is used.

HEM
Code Rate
PLP (physical layer pipe) types include Type 1 (data), Type 2 (data).
Choices are Yes or No.
The mode adaptation module can process input data in one of two modes, normal mode (NM) or high efficiency mode (HEM).
NM is in line with the Mode Adaptation in [i.3], whereas in
HEM, further stream specific optimizations may be performed to reduce signaling overhead.
The
BBHEADER (see clause 5.1.7) signals the input stream type and the processing mode.
Choices are 1/2, 3/5, 2/3, 3/4, 4/5, or 5/6.This
refers to the forward error correction (FEC) which uses the
LDPC (low density parity check) along with BCH code.

This is a bargraph indication which gives the relative pre ‐ filter RTAC RF sample level.
The maximum signal level span is ‐ 20dBm to +5dBm, but, if possible, it is better to attempt to keep the RF sample levels between ‐ 10 dBm and 0 dBm.
Since the sample levels at the sample cable outputs are usually too high, the level is adjusted by adding appropriate attenuation at the exciter sample input connectors.

Indicates the discipline of the OCXO (oven controlled crystal oscillator).
If the graph is green and extends almost all of the way to the right of the white window, the 10 MHz OCXO PLL is locked to the 1PPS reference, from the internal GPS receiver or the external 1PPS input, and is fully disciplined.
Under these conditions, it is capable of holdover (free running) and will remain within tolerance and allow transmitter operation for up to 100 hours.
The time out can be set from 1 hour to 100 hours in the PFRU Setup screen 2, which can be found in
OCXO Holdover Readiness graph percentage represents the difference between the maximum and minimum oscillator control value over a 20 minute window, and is the indication of how well disciplined the oscillator is.
If the holdover status value is above
90%, then the oscillator is only changing +/ ‐ 0.0003
Hz, and is good enough to use.
The value will never reach 100%, but when well disciplined should be 90% or greater.
The 10MHz OCXO is divided down to a 1Hz frequency and locked, via a phase locked loop, to a GPS 1PPS (pulse per second) reference signal.
The purpose is to create a synthesized
1PPS signal which is used as a timing signal, for example, to synchronize a single frequency network.
The 10 MHz OCXO signal is also used as a reference for the local oscillator, which determines the RF output frequency of the exciter.
The synthesized 1PPS signal will be present even when the GPS 1PPS reference is missing.
In that case, the 10 MHz OCXO holdover oscillator will be free running.
Holdover Time Remaining indicates the amount of time, in hours, minutes, and seconds, that the free running 10 MHz OCXO will remain within its frequency tolerance and the exciter will remain unmuted.
When the 1PPS reference is lost the 10 MHz OCXO is free running and the OCXO holdover
Readiness graph will start to diminish in accordance with the time remaining indication.
The holdover Time Remaining indication, located in the Holdover sub window, starts to count down from the setting (1 to 100 hours) entered in the PFRU Setup screen 2, which can be found in
When its time reaches zero the exciter will mute.
OCXO Stability does not depend on the Time Remaining value, OCXO oscillator stability is 3 ppb (parts per billion) per day.
When the reference is restored and the oscillator starts to lock, the OCXO Holdover
Readiness graph indication will be green and start to increase.
The exciter will remain muted until the OCXO is locked to the 1PPS signal.
The indication of the locked status is when the Time Remaining window changes from showing zero time to some value of time remaining.
As the green bar progresses to the right side of the window, the value shown in the time remaining window will increase.
When the OCXO is fully disciplined, the time remaining value will be equal to the time set into the PFRUSetup screen 6 (1 to 100 hours).

Explanation
Green = OK, Red = Mute.
If the digital modulator section is actively muted, this will indicate red.
In SFN situations, the exciter can only insert (add) delay.
If the timing parameters are improperly set at the transmission adapter or a network change (such as a substituting a satellite path for a microwave path to get the transport stream to the exciter) the exciter may determine that based on the resultant timing, the result indicates that it must remove delay to actually meet the emission timing.
This simply isn't possible and will be indicated.
Green = Delay < 1 second, red = delay > 1 second.
Transmitter delay, for SFN (single frequency network) data transmission synchronism, is measured against the 1PPS (pulse per second) pulse.
If transmitter delay exceeds 1 second, SFN data transmission synchronism is impossible.
Modulator has determined that it can no longer meet the required timing and it must mute it's output to re ‐ sync and increase the delay inserted

This is a read back of the maximum delay parameter being carried inside the Distributed
Transmission Packet.
It should match the value set in the Distributed Transmission Adapter.
This value is indicative of the maximum transport delay the network designer / operator expects to see.
It's maximum value is 100 nS less than 1 second.
This is the time from when a packet is released inside the transmission adapter until the time it arrives in the modulator.
It also includes a nominal amount of internal FIFO buffer hold time.
Time offset for emission contained in the Distributed Transmission Packet for this particular transmitter.
This is a dynamic indication of the amount of delay adjustment the modulator is computing.
Nominally this should be zero.
It often moves plus or minus 100 nS for minor adjustments.
Important that it is relatively stable, not wildly fluctuating.
Transmitter to antenna delay.
This the throughput delay, measured after the signal leaves the exciter network delay circuit and travels to the output of the transmitter.
This delay is important if the network consists of transmitters from different manufactures, where the output process time will change from one manufacturer to another.
This is the resultant total delay being managed by the timing requirements to meet the emission time, including TAD.
Number of delay increments that the modulator has had to perform to maintain emission timing.
High or continual incrementing numbers here indicate instability in the network's distribution of the transport stream or timing.
Ideally this is zero.
Number of delay decrements that the modulator has had to perform to maintain emission timing.
High or continual incrementing numbers here indicate instability in the network's distribution of the transport stream or timing.

Status
Exciter Home
Explanation
ATSC's A/110 standard specified two methods to achieve timing reference for SFN emission, they are GPS and stream locked.
In the stream locked mode, the exciter extracts it's timing from the 19.39
MHz clock embedded in the transport stream.
The exciter section only supports GPS locked mode.
This mode is set by the distributed transmission adapter.
If another manufacturer's adapter is being used and it has been set up for stream locked mode, the M2X will not lock and a fault will be indicated.
RF Watermark is a slow speed serial data stream that can be modulated onto each of the 8 symbol levels emitted.
This enables use of specialized test equipment in the field to figure out which transmitters are being received in an SFN environment.
In addition to transmitter identification, the RF Watermark can be used as a slow ‐ speed serial communication channel.
The M2X does not currently support this channel, but the
DTxA has the ability, in compliance with the standard, to tell a downstream modulator to inhibit the modulation of this data on the watermark or not.
This is a read back of the setting of that bit in the DTxP.
Bury ratio tells how many dBs the RF watermark is “buried” underneath the main 8 modulation levels of the symbols.
0 = off, no ratio
1 = 39 dB below the main.
2 = 36 dB below the main.
3 = 33 dB below the main.
4 = 30 dB below the main.
5 = 27 dB below the main.
6 = 24 dB below the main.
7 = 21 dB below the main.
A warning will appear in the fault log for levels of 5 or higher, indicating that the output signal to noise achievable is being limited by the RF watermark insertion.

Active
Logic
Symbols
Each logic signal has an active and inactive state and a unique name within the system.
To differentiate between active high or active low logic states on the schematics, a forward slash (/) is placed in front of an active LOW signal name such as /RF_MUTE.
This means that if this logic line is pulled low, the transmitter RF will be muted.
By the same logic, the signal RF_MUTE_LED (an active high signal with no forward slash) will turn on the RF mute LED when it goes high.
In some cases, a logic signal may act as a toggle with both states active, as with the signal /ON_OFF, where LOW =
ON and a HIGH = OFF.
If this signal is inverted it would be ON_/OFF.

gives the basic Maxiva model numbers and configurations.
Figure 4 ‐ 1 is a simplified transmitter system RF block diagram.
This diagram shows the transport stream input to the modulator, the modulator RF output signal connected to the driver input, and the PA output connected to the PA directional coupler.
Outside the transmitter enclosure, the output of the PA coupler is connected to the high power filter input and the output of the high power filter connected to the directional coupler.
The coupler output is connected to the antenna or the test load.
Two RF feedback signals are connected from the transmitter RF output system to the modulator.
These feedback signals are taken before and after the high power filter, and are needed to perform the non ‐ linear and linear RTAC
(real time adaptive correction) precorrection of the modulator RF output signal.
The PA (pre filter) RTAC feedback signal is internally routed in the transmitter.
The high power filter and its output coupler are located outside the transmitter enclosure, and therefore the post ‐ filter RTAC feedback signal is routed externally from the output coupler to an SMA connector on the rear panel of the transmitter.
See
Section Figure 1 ‐ 3 on page 1 ‐ 3
for the post ‐ filter sample connector.
RTAC precorrection is used to cancel the nonlinear distortions generated in the PA assembly and the linear distortions generated in the high power bandpass filter.

4.4.1
Signal Processor Board Overview
The signal processor board serves as a motherboard for the UAX ‐ C transmitter.
The board interfaces to virtually all the boards in the transmitter.
Refer to
The signal processor board also serves as the ASI input and output, decoder and encoder, the modulator, the digital precorrector (RTAC circuit for digital modulation modes), and it contains the ADC and DAC which interface to the up/ downconverter board RF connections.
The signal processor board has control interfaces to the transmitter I/O
Interface board, the PA interface board (which in turn connects to the up\down converter board), the PFRU board, the front panel, and the LVPS.
Power for the signal processor board is derived from the LVPS, which delivers +5V DC, +12V DC, ‐ 12V DC, +24V DC, and +12VBATT.
All other voltages necessary for the signal processor board are derived from these inputs.
All boards receive their power through the signal processor board.
Monitoring of the power supplies and ambient temperature are performed by the micro module, which is a daughter board mounted on the bottom right, rear corner of the signal processor board.
The micro module also initiates offline tests requested by the user, such as memory tests, serial channel loop back, predefined board level tests, and predefined LPU tests.
The signal processing board has two principal subsections: the Modulator (MOD) FPGA and the Digital Upconverter
(DUC) FPGA.
4.4.2
The Modulation Process
The transport stream inputs are applied to the FPGA modulator.
The modulator processes the transport stream and recovers the data and the clock.
In some modulation standards, the clocks required to synchronize several circuits in the signal processing board are phase locked to the recovered transport stream clock.
During the modulation process the FPGA modulator adds forward error correction to the digitized signal.
This forward error correction includes, but is not limited to, data randomization, Reed ‐ Solomon coding, data interleaving, and trellis coding.
Some modulation methods may use convolutional coding and frequency division multiplex.
The signal is also band ‐ limited using a digital filter.
The FPGA modulator sends the digitized, processed, and bandpass filtered IF signal to the digital upconverter and precorrector circuit.
The precorrector uses RTAC to apply precorrection to the digitized IF signal based on the down converted, digitized
RF samples from before and after the high power filter.
The fully processed and precorrected digitized IF signal, resulting from various digital operating modes, is processed into a 140 MHz (center frequency) IF signal by the DAC (Digital to Analog Converter).
The 140 MHz IF signal is sent to the upconverter circuit of the up/downconverter board, where it is heterodyned up to the on channel frequency and amplified.
The modulator maximum output level is 6 dBm (4 mW average) in any digital mode.
4.4.3
RF Sample Processing
The RTAC algorithm compares the processed and filtered digitized IF signal from the modulator to the digitized samples from the transmitter output in order to apply the correct precorrection to the signal to cancel linear and nonlinear distortions appearing at the output.
The RF samples for the RTAC algorithm must be selected one at a time, the level set, the sample down converted to the 140 MHz IF frequency, and then digitized and sent to the digital precorrector circuit.
The input to the downconverter is an electronic switch, which is controlled by the signal processor board.
The level of the selected signal is set to the optimum level for the downconverter mixer by an attenuator, which is controlled by the signal processing board.
The signal is next applied to a mixer, along with the local oscillator signal from the 2nd local oscillator phase lock loop circuit in the precise frequency reference board.
The resultant 140 MHz IF signal is then filtered to remove mixing products and sent to an attenuator controlled from the signal processor board.
Here its level is set to optimum for its next destination, the ADC (Analog to Digital
Converter) in the signal processor board.

Low Voltage Power Supply Board
The low voltage power supply for the modulator is mounted to the left inside wall of the transmitter chassis.
The following items are mounted on the power supply assembly:
•
The AC Input connector.
•
A +12V switching power supply, mounted towards the rear of the power supply assembly.
•
Provision for an optional battery backup board, mounted at the front of the power supply board.
•
The LVPS distribution board receives +12 V DC from the switching supply.
It uses it to generate the +24 V
DC, +5 V DC, and ‐ 12 V DC outputs from DC to DC converters.
•
The +24V, +12V, +12Vosc, +5V, and ‐ 12V are DC outputs supplied via a ribbon cable to the signal processor board.
Power to the other boards is distributed via the signal processing board to the other subsystems.

Battery Backup Option
The battery backup board interfaces directly to the LVPS board.
Three Lithium ‐ ion cells are used in a series arrangement and provide 9.6
volts at 1200mAh, 12WHr rated.
The battery backup assembly consists of a battery backup circuit board with three Lithium ‐ ion cells permanently attached; it also includes a custom battery charging circuit and protection circuitry.
The batteries and circuit board are sold as a unit when replacement batteries are required.
The battery backup assembly part number is 971 ‐ 0051 ‐ 012G.
The battery backup supplies the LVPS board with +6.4V
to 10.8V
at 20A maximum.
It is mounted directly to the LVPS board.
A block diagram of the battery backup assembly is shown in
The battery backup assembly specifications are as follows.

•
Under the optimum battery condition, this battery backup option is capable of one minute of operation of the modulator portion of the UAX ‐ C transmitter following an AC mains power failure.
This is accomplished by keeping the +24V, +12V, +12Vosc, +5V, and ‐ 12V power supply interface board DC outputs energized for one minute following a power failure.
During this time, the PA assembly is not powered.
•
It keeps the oscillator circuits and the internal GPS receiver operating for an additional thirty minutes fol ‐ lowing the one minute modulator backup operation.
It accomplishes this by de ‐ energizing all but the
+12Vosc power supply outputs.
•
During the last thirty minutes of battery backup operation, the battery backup maintains power to the
10MHz and 1PPS Input circuitry on the signal processing board and the FPGA, OCXO and GPS circuitry on the PFRU.
By powering these circuits, the modulator can maintain the 10MHz OCXO discipline loop when the transmitter loses power.
The OCXO can take three minutes to stabilize from a cold start, and the disci ‐ pline loop itself can take an hour to reach the maximum precision; having the discipline loop active during a power outage enables the UAX ‐ C transmitter to return to air faster and with greater frequency accuracy.

The modulator FPGA also provides an ASI monitor output.
The ASI monitor output is at LVDS levels from the FPGA.
It utilizes an LVDS (Low Voltage Differential Signal) driver and transformer per the ASI specification.
The DUC (Digital Up Converter) FPGA is responsible for taking the modulated data and applying correction, as well as up converting the baseband signal allowing the system to come out on the correct frequency to feed to the DAC.
The
DUC FPGA output data is then transferred to the DAC to be converted to a 140 MHz IF, which is then up ‐ converted to the on channel frequency.
The DUC writes the 16 ‐ bit I and Q data to the AD9779 DAC.
The DAC is clocked by the ~409 to 460 MHz clock from the PFRU.
The 1/4 F
DAC clock output of the DAC is used as a clock for the DUC FPGA and the RF Sample ADC.
The DAC provides the up/down converter board with the 140MHz IF.
The AD9461 ADC is clocked by the 1/4 FDAC clock.
It converts the 140 MHz IF from the downconverter to a 16 bit sample provided to the DUC FPGA.
The ADC also provides the DUC FPGA with the sample A/D clock.

DAC clock frequencies for various modulation methods is shown in
Each modulation method produces an IF frequency which is equal to 1/4 of the DAC clock frequency for that modulation system.
Therefore, an offset frequency is produced by the FPGA modulator to bring the IF frequency to
140 MHz.
The required offset frequency for each modulating system can be calculated using the following formula.

This circuit features an 800 to 1600 MHz voltage controlled oscillator, which is phase locked to a 10 MHz reference signal.
The relationship between the various on channel frequency bands, the required local oscillator frequencies, and the status of the IF signal is given below and summarized in
•
For band V and band IV, the oscillator output is divided by two, yielding an output range of 400 to 800 MHz.
This signal is sent to the up/downconverter board.
•
For band V, the on channel output frequency is the sum of the IF and the local oscillator signals, therefore, the IF signal is not inverted.
•
For Band IV, the on channel output frequency is the difference between the IF and the local oscillator sig ‐ nals, therefore, the IF signal must be inverted.

Figure 4-8 Upconverter Block Diagram
The upconverter base board accepts a 140MHz IF at a 0 dBm average level from the signal processing board via J7.
The 140 MHz IF is filtered primarily by the low ‐ pass portion of a bandpass filter, which suppresses the unwanted DAC signals at 258MHz and above.
The filtered IF is applied to a variable attenuator, which is used to set the RMS level to the optimum level for the mixer in order to minimize spurious mixing products.
This attenuator is set to a specific fixed value by the system controller depending on the modulation format.
A directional coupler applies a sample of the IF to a detector IC, which provides a voltage output proportional to the RMS level of the IF.
This voltage is A/D converted and utilized by the controller for diagnostic purposes primarily to detect a low/missing input condition.
The signal leaves the base board via J5 and is sent to the UDC top board.
The IF signal enters the UDC top board via J7.
The IF is applied to the mixer through a fixed pad and a bridged T network.
This provides a very good match, from DC to very high frequencies, to the IF port of the mixer which helps to minimize 3rd order mixing products, i.e.
(2*IF) ‐ LO.
The mixer output is buffered by a MMIC (Monolithic
Microwave Integrated Circuit) amplifier.
The signal is next sent to a two stage UHF tunable bandpass filter, which removes the undesired mixing products.
In each filter stage, the filtered RF is buffered by a MMIC amplifier.
After the filtering process the RF signal is applied to a mute circuit, which consists of a SPDT low ‐ loss, high isolation
(60dB @ 1.5GHz) microwave relay.
When muted, the normal RF path is opened and the RF switched into a 50 load.
The RF is then passed through a low pass filter, gain adjusted by a variable attenuator, and sent to an amplifier.
The amplifier is followed by a low ‐ loss directional coupler, with the main coupler path leaving the up converter via J1 and being sent to the power amplifier assembly elsewhere in the transmitter chassis.
The coupled RF sample is applied to an AD8362 demodulating detector IC.
The detector output is heavily low ‐ pass filtered to provide average power measurement.

The downconverter accepts the following on ‐ channel RF inputs:
•
Transmitter system PA (pre ‐ filter) sample for non ‐ linear estimation.
•
Transmitter system HPF (post ‐ filter) sample for linear estimation.
The two RF sample inputs are each applied to a high ‐ isolation two ‐ way switch IC.
The selected sample is routed through its respective two ‐ way switch to the final 2 ‐ way selector switch, while the undesired input is switched into a resistive load.
This arrangement provides very good isolation of the signals and a good absorptive match to the input in the de ‐ selected state.
The selected RF sample is passed through a 900 MHz low pass filter and then variably attenuated, buffered, and split.
One path feeds a power detector, which provides a DC sample used by the controller to adjust the attenuator for optimum RF level into the mixer.
The other path is amplified and applied to the mixer input.
The IF output of the mixer is applied to a bridged ‐ T network, buffered by a MMIC amplifier, and low ‐ pass filtered with a 225 MHz SMT low ‐ pass filter.
This filter removes unwanted mixing components from UHF conversions while being transparent to the 140MHz IF in terms of amplitude response and group delay.
This IF leaves the up/down converter top board via
J8 and is sent to J6 on the up/down converter base board.
In the up/down converter base board, the filtered IF is buffered and variably attenuated to allow the controller to optimize the level into the A/D converter in the signal processing board.
A high linearity output amplifier drives the
IF output to the ADC.

The 971 ‐ 0051 ‐ 055 PA module used for the UAX ‐ 100 ‐ C model
The two modules are easily distinguishable by these differentiating features:
The 971 ‐ 0051 ‐ 020G has separate amplifier, amplifier interface, and output coupler subassemblies, whereas the 971 ‐

Figure 4-12 Block Diagram UAX-C Transmitter 5-80 Watt PA
The 970 ‐ 0051 ‐ 020G power amplifier has three amplifying stages in series: a class A stage providing 18dB gain, a class
AB stage providing 18 dB of gain, and a final stage consisting of two push ‐ pull class AB pairs operating in parallel to provide 21 dB gain.
A resistive 12dB attenuator pad precedes the first driver stage to limit the total gain to 45 dB.
The first stage (pre driver) of the amplifier assembly consists of 1 FET transistor (Q5) operated class A.
The drain current of 100 mA is sampled in R17 and its resultant voltage drop (which is proportional to the drain current) is applied to regulator CR4, CR6, CR7, U7, and Q2.
The output of this regulator is the Q5 gate bias voltage.
The result of this arrangement is that the Q5 drain current remains constant from zero signal to full signal.
The second stage is the driver, which consists of one FET transistor (Q4) operated class AB.
Q4 idle current is 150 mA, and is set by adjusting the Q4 gate bias.
Gate bias for Q4 is set by adjusting R25, with the bias voltage source consisting of U8, U4, CR2, and R190.
U8 is a temperature sensor which monitors the temperature of Q4 and varies its bias in order to eliminate temperature caused drain current drift.
The output of driver stage Q4 is applied to quarter wavelength hybrid (HY1), which is the splitter for the two PA push pull amplifiers.
Each of the two push pull amplifiers consist of two FET transistors.
One amplifier consists of Q1 and
Q2 and the outer consists of Q6 and Q7.
The two output of HY1 are 90 degrees out of phase, which causes the two push pull amplifiers to operate 90 degrees out of phase.
HY2 is also a quarter wavelength hybrid, which combines the two 90 degree outputs of the push pull amplifiers.

The advantage of operating the PAs 90 degrees out of phase is that any reflected signal arriving back to the PA assembly output will be reflected from the PA transistors and end up in the combining hybrid reject load, R49.
This arrangement prevents 2nd reflections from being sent back up the transmission line and being transmitted.
Idle current for the four PA transistors, Q1, Q2, Q6, and Q7, is 300 mA each.
Idle current is set by varying the gate bias of the PA transistors.
Since the bias circuits for all four transistors are the same, only that of Q1 will be discussed
Gate bias for Q1 is set by adjusting R3, with the bias voltage source consisting of U1, U2, and CR10.
U2 is a temperature sensor, which monitors the temperature of Q1 and varies its bias in order to eliminate temperature caused drain current drift.
The output of U2 is also sent to the PA interface board, which sends it to the signal processor board, which uses it to determine and display the PA transistor temperature.

100 Watt PA Amplifier 901 ‐ 0051 ‐ 055
Figure 4-13 Block Diagram UAX-C Transmitter 100 Watt PA
The 971 ‐ 0051 ‐ 055 power amplifier has three amplifying stages in series: a class A stage providing 19dB gain, a class
AB stage providing 15 dB of gain, and a final stage consisting of a push ‐ pull class AB pair operating in parallel to provide 19 dB gain.
The first stage (pre driver) of the amplifier assembly consists of a TQP7M9105 monolithic RF amplifier (U1) operated in class A.
It operates with +5V and has a quiescent current of 220 mA.
The second stage is the driver, which consists of one FET transistor (Q1) operated in class AB mode.
Q1 idle current is
300 mA, and is set by adjusting the Q1 gate bias.
Gate bias for Q1 is set by adjusting R81, with the bias voltage source consisting of R1, R81, R71, and RT1.
RT1 is a temperature sensing thermistor, which changes its internal resistance as a function of temperature.
This modifies the voltage drop across R1 and thus the bias voltage presented to the gate of Q1, with the goal of eliminating changes to the bias point/idle current of Q1 due to temperature changes as the amplifier heats up.
The output of driver stage Q1 is applied to a quarter wavelength hybrid (HY1) printed on the circuit board, which serves as the splitter for the two final push ‐ pull amplifiers, Q3 and Q4.
The two outputs of HY1 are 90 degrees out of phase, which causes the two push ‐ pull amplifiers to operate 90 degrees out of phase.
A second printed quarter wavelength hybrid HY2 at the final stage output combines the outputs of the push ‐ pull amplifiers.
The advantage of operating the PAs 90 degrees out of phase is that any reflected signal arriving back to the PA assembly output will be reflected from the PA transistors and end up in the combining hybrid reject load, R79.
This arrangement prevents secondary reflections from being sent back up the transmission line and being transmitted.
Idle current for the final transistors, Q3 and Q4 are 900mA, each.
Idle current is set by varying the gate bias of the PA transistors.
Since the bias circuits for both transistors are essentially the same, only that of Q3 will be discussed
Gate bias for Q3 is set by adjusting R83, with the bias voltage source consisting of R19, R73, R70, and RT2.
RT2 is a temperature sensing thermistor, whose temperature compensating action on the bias applied to Q3 is essentially the same as that of RT1 on the bias applied to Q1, as described previously in this section.
A PA temperature sample for the amplifier control and alarming is obtained via voltage divider R80 and thermistor
RT3.

PA Interface and Control Functions
PA interface and control is provided by a separate board ‐ the PA interface board (901 ‐ 0233 ‐ 031G) ‐ in the case of the 9710051 ‐ 020G PA module.
In the case of the 971 ‐ 0051 ‐ 055 PA module (UAX ‐ 100 ‐ C), the functions described here are provided by circuits integrated directly on the main power amplifier board (901 ‐ 0233 ‐ 281)
The purpose of the PA interface is to act as an interface between the signal processor board and the small signal RF and power amplification stages.
It also bridges communication, control/status and DC voltages to and from the AC/
DC converter (+50V power supply), power amplifier, and UHF up/down converter boards.
4.5.3.1
Fault Protection
The PA interface board provides fault protection against the following conditions:
•
Over current of any of the PA FETS
•
Over voltage of the +50V power supply
•
VSWR Protection in severe conditions too fast for and above the foldback threshold.
•
Over temperature of any of the PA FET.
4.5.3.2
Power Measurement
The PA interface board also has on ‐ board RF detectors to determine the forward and reflected power levels based on RF samples coming from a microstrip coupler at the PA output.
Power calibration can be performed while operating (this of course assumes that the end user has a well ‐ calibrated directional coupler and a power meter connected ex ‐ ternally).
The calibration points and frequency of calibration are stored in an EEPROM by the control system.
Basic frequency compensation of the output cou ‐ pler response is provided by mathematical formulas in the control system.
Upon a channel change, the resulting power calibration should be reasonably close to correct until a new calibration can be performed and stored at the new operating frequency.
4.5.3.3
50V Power Supply Interface
An AC/DC converter is used to provide the +50VDC required by the LDMOS devices in the PA assembly.
The PA
Interface uses a 2N7002 in an open drain configuration.
When turned on, the 2N7002 provides the ground to enable the AC/DC converter.
The AC/DC converter has an open collector status output which is grounded when the supply is on and no faults are present.
The /PS_PRESENT pin is grounded on the power supply end, with a 10k pull ‐ up on the
PA interface, to indicate a cable connection to the supply.
4.5.3.4
DC Distribution and Current Monitoring
The PA Interface board accepts +5V, +/ ‐ 12V, and +24V from the signal processor board.
All four voltages are distributed to the UDC board and +24VDC is distributed to the PA (971 ‐ 0051 ‐ 020G PA only), along with the +50V.
The current consumed by the PA stage is monitored via low value current shunt resistors connected in series and
INA168/AD8213 differential amplifiers.
The PA output FET +50V currents are monitored differently according to transmitter model.
•
For the 5 ‐ 80 watt amplifier (971 ‐ 0051 ‐ 020G), the GUI screen "PA 1 Id" represents the combined drain cur ‐ rent drawn by PA FETs Q6 and Q7, whereas the GUI screen "PA 2 Id" represents the combined drain current drawn by PA FETs Q1 and Q2.
Typical idle current is 300mA for each pair.
Typical full ‐ power current at 50W is 3A per pair.
The over ‐ current trip point is 5A for each pair of PA transistors.
•
For the 100 watt amplifier (971 ‐ 0051 ‐ 055), the GUI screen "Current " value represents the combined drain current drawn by both the driver stage and the dual push ‐ pull final stage.
A typical idle current is 2.2A.
Typ ‐ ical full ‐ power current at 125W is 11A.
The over ‐ current trip point is 17A.
The +24V powers the pre driver and driver amplifiers in the 971 ‐ 0051 ‐ 020G PA (i.e.
all tx models except the UAX ‐
100 ‐ C).
The GUI current indication is the combined current for both the pre driver and driver transistors (referred to as Drv 1&2.) The pre driver is operated class A and has a current of 100mA.
The driver is operated class AB and has an idle current of 150mA.
Total current for both transistors is typically 340mA for a PA operating at 50 watt, and the
24 volt current trip point is 500mA.
These readings are absent on the UAX ‐ 100 ‐ C model.

Power
Calibrations
Note
The following calibration procedures are for all digital modulation formats, such as DVB, ISDB-T, and
ATSC. This procedure does not address analog modulation formats, such as NTSC, PAL, and SECAM.
Caution
FORWARD AND REFLECTED POWER CALIBRATIONS SHOULD ONLY BE
DONE WHILE OPERATING THE TRANSMITTER INTO A KNOWN GOOD LOAD
SUCH AS A STATION DUMMY LOAD. BE CERTAIN THAT THE LOAD IS A
CONFIRMED 50 OHMS AND HAS THE CAPABILITY TO HANDLE THE POWER
THAT WILL BE GENERATED BY THE TRANSMITTER.
Power calibrations can be performed using the local LCD screen or the web browser interface.
Calibrations performed via web browser interface require a user login and password at the admin level.
Transmitters ship from the factory with the default login "admin" and the default password "admin" (do not include quotation marks in login or password, and login and passwords are case sensitive).
If you change passwords, be sure to retain a record of them in a secure location.
You will not be able to make changes to transmitter settings via web browser without a valid password.
Harris Broadcast recommends the Firefox web browser but Chrome or IE8 (or greater) can be used as well.
Refer to
In the ’System Configuration’ screen select soft key ’Cal’.
If logged in via web browser, the following screen (in HTML format) will be displayed to facilitate Calibration.
Figure 5-6 on left - System Calibration on right - System Calibration options
The procedures described below assume use of the UAX ‐ C LCD menus screens.
Power calibrations include:
•
Factory Fwd/Rfld ‐ System forward and reflected power at output of transmitter before band pass filter
(BPF).
Typically performed at the factory during final test.
This calibration requires that the transmitter drop to a very low power for a short period and is thus not recommended for use while the transmitter is in service.
•
Field Fwd/Rfld ‐ System forward power at output of transmitter before BPF.
Typically performed at operat ‐ ing frequency and power level for maximum accuracy.
Intended to be a quick "touch ‐ up" correction for when minor discrepancies in calibration are detected.
This calibration does not require a drop in power and can be performed safely at any time.
Equipment Used:
•
An averaging power meter (with probe) similar to the Agilent E4418B with appropriate adapters.
Meter should be capable of displaying measured values in Watts or in dBm.
•
Precision directional coupler (the coupling value has been measured to a high degree of precision for the desired operating frequency).

Note
Read and understand the applicable power calibration procedure before beginning. The procedures below assume use of the LCD display and the control buttons on the front of the UAX-C. The procedure can also
be performed using web browser screens. Web browser calibration screens are shown in Figure 5-6.
Figure 5-7
Typical Output Directional Coupler and Connections
5.4.1
Factory Fwd/Rfld Calibration
The factory forward power calibration is performed over a range of 10dB below model power to full model power
(i.g., 5W to 50W for a 50W digital system.) The forward power reference sample is taken from the internal directional coupler and regulates the power of the transmitter output before any filter losses.
Reflected power is automatically calculated as the calibration routine is processed.
Calibration data is stored internally on an EEPROM.
The system detectors utilize a linear (in mV/dB) output, so by performing a two ‐ point calibration, the detector slope can be calculated so as to provide good accuracy over a broad 10% ‐ 100% power range.
STEP 1
Zero and calibrate the RMS power meter, following the manufacturer’s procedures for that specific model.
STEP 2
Install a directional coupler at the output of the transmitter.
The directional coupler must be capable of handling the rated transmitter output power and have defined coupling values to allow accurate measurements of forward power levels.
Couplers furnished by Harris Broadcast, such as the unit shown in Figure 5 ‐ 7, are typically accompanied by a printed sheet listing the coupling values at various frequencies across the UHF band.
Consult this sheet to determine the coupling value in dB at the current operating frequency.
Note
Couplers like the one shown in Figure 5-7 use one port as a coupled port while the opposite port is terminated in an external 50 ohm load. The load must be installed in order to perform accurate measurements.
Caution
DO NOT APPLY EXCESSIVE DOWNWARD PRESSURE (WEIGHT) ON THE
TYPE N OUTPUT CONNECTOR. IF A DIRECTIONAL COUPLER IS ATTACHED
DIRECTLY TO THE OUTPUT CONNECTOR IT SHOULD BE ADEQUATELY
SUPPORTED. EXCESSIVE STRESS ON THE CONNECTOR MAY CAUSE
INTERNAL DAMAGE AND RESULT IN HIGH VSWR CONDITIONS OR
COMPLETE LOSS OF POWER OUTPUT.

STEP 3
Once the coupler coupling value is determined, enter this value as a power meter offset.
Set the meter’s display to read in dBm or Watts, and connect the power meter sensor to the forward coupler port.
Note
The sample level present at this coupler port (transmitter power output level minus coupling value) must not exceed the maximum input range of the power sensor in use.
Note
Calibration must be performed with the transmitter operating into a known good load or antenna system.
If reflected power rises to a level that exceeds 10% of forward power, stop raising power. Turn off the transmitter and begin checking the output components (transmission line, load, antenna) for faulty components capable of producing high levels of reflected power.
STEP 4
Connect the transmitter output to a known good RF load.
If required, use a short, high quality, low VSWR.
STEP 5
Apply AC mains power to the transmitter chassis.
STEP 6
Press the Remote Disable button on the front of the transmitter to eliminate the possibility of transmitter activation via remote control.
STEP 7
Press and hold the Power Lower button for 20 seconds to lower transmitter output power at turn on.
STEP 8
Press the transmitter On button while monitoring transmitter forward power on the external power meter.
Monitor reflected power on the LCD screen.
Slowly raise the power to the desired operational power level and allow the transmitter to run for several minutes until the output power level is stable.
STEP 9
Compare the external power meter value with the forward power reading displayed on the LCD screen.
If the values do not agree, proceed with calibration.
STEP 10
Use the LCD screen and control buttons to navigate to the calibration menu SETUP >
XMTR POWER SETTINGS > POWER CAL > FACTORY FWD/RFLD.
Press the Enter button
(center) one time to highlight the menu, and use the Up/Down keys to select the
Factory Fwd/Rfld option.
STEP 11
Start the calibration procedure by pressing the Enter button again.
STEP 12
Follow the instructions on the LCD screen and use the power Raise/Lower buttons to adjust the transmitter output to the desired low level.
When a stable reading is attained on the power meter, select Save and press Enter.
Note
It is helpful to check the RF DAC value displayed (in hexidecimal notation) on the calibration screen. In a system that is properly configured and operating correctly, a DAC value exceeding 860 without the output having reached the desired low power level indicates a possible problem.
STEP 13
Follow the instructions on the screen, and use the power Raise/Lower buttons to adjust the transmitter output to the desired high level.
When a stable reading is attained on the power meter, select Save and press Enter.
Note
It is helpful to check the RF DAC value displayed (in hexidecimal notation) on the calibration screen. In a system that is properly configured and operating correctly, a DAC value exceeding A73 without the output having reached the desired high power level indicates a possible problem.
STEP 14
Procedure complete.
Note
If any components in the amplifier section are faulted during the calibration, the system will consider the calibration invalid and discard it. Replace any faulty components and perform the calibration again.

Changing
Frequency
This procedure describes a manual change of the channel frequency to a new value.
It is always advisable to first save the settings on the initial channel before proceeding with a frequency change.
Once operation on the new frequency has been established, a second set of settings should also be saved.
This will greatly facilitate changing between frequencies in the future by simply duplicating the previously recorded settings.
The settings can be saved using the web browser and navigating to Tx Home > Exciter Home > Setup > ISP > Save Settings.
This discussion assumes that the frequency will be changed manually and somewhat infrequently.
Required Tools:
•

General MIB Description
The Harris Broadcast MIB is usable in all NMS (Network Management Systems) and is provided in text ‐ format.
The advantage of this monitoring system is that there is no difference between the monitoring of various models of
Harris Broadcast equipment.
Once the MIB is integrated into the NMS, all different devices can be monitored via the central station.
For complete control and monitoring functionality, an Internet browser has to be opened in the NMS, and various devices can be accessed.
5.14.3.1
MIB Functionality
Monitoring:
Main keys of the MIB 2 are supported (e.g.
name, location), to classify the device.
The Harris Broadcast specific MIB allows monitoring of the main values of the device (e.g.
Error, Warning, Output present) via
SNMP.
Control:
Only rudimentary commands are included in the Harris Broadcast MIB (e.g.
switch transmitter on/off).
For security, the device control via SNMP must be activated in the equipment.

6.1
Introduction
This section contains diagnostic and troubleshooting information for the UAX ‐ C series UHF transmitter.
Included is a complete description of all faults that can be displayed via the transmitter front panel LCD or web interface.
Due to the complexity of the transmitter control system and the extensive use of surface mount components, the scope of this diagnostics section is to isolate the problems to a PC board or module, which can then be easily exchanged.
The buttons and icons used in the web browser use a color code system.
Some examples are given below.
a.
Green with a 1 ‐ ‐ ON and operating normally.
b.
Green symbol ‐ ‐ ON and operating normally.
c.
Light Gray ‐ ‐ "Grayed Out" ‐ Not communicating or not available.
d.
Yellow ‐ Warning ‐ A non ‐ critical sub ‐ system or parameter is out of tolerance and should be addressed by engineering personnel.
e.
Red ‐ ‐ Critical Fault ‐ This could be a sub ‐ system fault in which the sub ‐ system is muted or shut off
(such as a PA module) or could be a system level fault, which could mute or shut the transmitter off.
When a fault occurs, one or more of the LEDs on the transmitter control panel will illuminate red.
To track down the cause of the fault, open the transmitter fault log via the web GUI interface and see which faults have occurred and in what order.
If you are not familiar with web browser navigation, refer to Section.
and to
Section
below.
The fault log on the LCD (in Status menu) will also give detailed fault information but is smaller and takes longer to read, as it only shows four faults per page.
If the fault information is more than 11 characters, the description is truncated.
If this occurs refer to the web browser for complete fault description.
Fault log information is stored on
EEPROM and is thus retained, if AC mains power is cycled.
6.2
Web
Browser
Fault
Log
The web browser interface allows access to a fault log that lists all faults or warnings that have occurred.
The UAX ‐ C fault log is accessed by pressing the Fault Log soft button on the right side of the UAX ‐ C Exciter Home screen.
This will bring up the UAX ‐ C Fault Log ‐ All Faults screen.
The fault logs give the following information: a.
Order ‐
The UAX ‐ C fault log stores up to 500 entries, after which, faults are deleted on a first ‐ in first ‐ out
(FIFO) basis.
The last fifty faults can be viewed in the UAX ‐ C fault log.
The entire fault log including older faults can be viewed or exported via the web browser by navigating to the UAX ‐ C Status screen and press ‐ ing Export FltLog.
b.
Set
‐ Time (24 hour format) and date (month, day, year) that the fault occurred.
c.
Clear
‐ Time and date that the fault was cleared.
If the fault is still active, the Clear field will be blank.
d.
Name
‐ Name and description of the fault.

List
Information
The Replaceable Parts List Index portrays a tree structure with the major items being left most in the index.
The example below shows the Transmitter as the highest item in the tree structure.
If you were to look at the bill of materials table for the Transmitter you would find the Control Cabinet, the PA Cabinet, and the Output Cabinet.
In the Replaceable Parts List Index the Control Cabinet, PA Cabinet, and Output Cabinet show up one indentation level below the Transmitter and implies that they are used in the Transmitter.
The Controller Board is indented one level below the Control Cabinet so it will show up in the bill of material for the Control Cabinet.
The tree structure of this same index is shown to the right of the table and shows indentation level versus tree structure level.

The part number of the item is shown to the right of the description as is the page in the manual where the bill for that part number starts.
Inside the actual tables, four main headings are used:
•
Table # ‐ #.
ITEM NAME ‐ PART NUMBER ‐ this line gives the information that corresponds to the Replaceable
Parts List Index entry;
•
PART NUMBER column gives the ten digit Harris Broadcast part number (usually in ascending order);
•
DESCRIPTION column gives a 25 character or less description of the part number;
•
REF.
SYMBOLS/EXPLANATIONS column 1) gives the reference designators for the item (i.e., C001, R102, etc.) that corresponds to the number found in the schematics (C001 in a bill of material is equivalent to C1 on the schematic) or 2) gives added information or further explanation (i.e., “Used for 208V operation only,” or “Used for HT 10LS only,” etc.).
NOTE: Inside the individual tables some standard conventions are used:
•
A # symbol in front of a component such as #C001 under the REF.
SYMBOLS/EXPLANATIONS column means that this item is used on or with C001 and is not the actual part number for C001.
•
In the ten digit part numbers, if the last three numbers are 000, the item is a part that has been purchased and has not manufactured or modified.
If the last three numbers are other than 000, the item is either manufac ‐ tured or is purchased from a vendor and modified for use in the Harris Broadcast product.
•
The first three digits of the ten digit part number tell which family the part number belongs to ‐ for example, all electrolytic (can) capacitors will be in the same family (524 xxxx 000).
If an electrolytic (can) capacitor is found to have a 9xx xxxx xxx part number (a number outside of the normal family of numbers), it has probably been modified in some manner at the factory and will therefore show up farther down into the individual parts list
(because each table is normally sorted in ascending order).
Most Harris Broadcast made or modified assem ‐ blies will have 9xx xxxx xxx numbers associated with them.
The term “SEE HIGHER LEVEL BILL” in the description column implies that the reference designated part number will show up in a bill that is higher in the tree structure.
This is often the case for components that may be frequency determinant or voltage determinant and are called out in a higher level bill structure that is more customer dependent than the bill at a lower level.
