CL1TC-4 400W DVB-H Transmitter Product Description Product Manual, Rev. 1 14 ACACUSBETHERNETRS-232I/O(Cabinet Alarms) Figure 2-6 DVB-H Transmitter Block Diagram
CL1TC-4 400W DVB-H Transmitter Product Description Product Manual, Rev. 1 15 2.3.4 Modulator The modulator includes • DVB-H modulator • Amplifier • Bandpass filter • GPS receiver • I/O extension board • System controller Power to the modulator is protected using a UPS power backup (see Figure 2-6). This will ensure site monitoring will continue during a power outage as well as continued signal generation to ensure a fast recovery time once power is restored. 2.3.4.1 DVB-H Modulator • The module performs DVB-H signal encoding, OFDM waveform generation and has the ability to synchronize with other stations to provide Single Frequency Network (SFN) operation. • The module performs the frequency conversion of the OFDM signal into the required L-Band channel frequency, to drive the high power amplifier (HPA). • Digital Linear and Non-linear pre-correctors provide compensation for the group delay introduced by the HPA output filter and the non-linear distortions produced by HPA. The DVB-H Modulator receives a MPEG-2 structured Transport Stream on the ASI input or an IP encapsulated MPEG-2 structured Transport Stream on either of the RJ-45 Ethernet ports. The IP input is according to MPEG PRO CoP #3 FEC / SMPTE 2022 protocol. The modulator converts the digital input streams (ASI or IP) to an OFDM waveform in accordance with DVB-T/H standards. A direct conversion process provides a single analog RF output from 1670 MHz to 1675 MHz, suitable for amplification in the high power amplifier (HPA). Digital linear and non-linear pre-correctors (pre-distorters) significantly improve the performance of the high power amplifier. The Non-linear pre-corrector compensates for the HPA non-linearity and is able to provide separate adjustment for the low and high frequency shoulders of the wide channel spectrum. The Linear pre-corrector compensates for the group delay created by an output filter. 2.3.4.2 Amplifier The amplifier provides up to 20 dB of gain, allowing the modulator to provide an RF output power level from -10 dBm to 0 dBm with shoulders > 55dBc.
CL1TC-4 400W DVB-H Transmitter Product Description Product Manual, Rev. 1 16 2.3.4.3 Bandpass Filter Each modulator is equipped with a narrow-band output filter specifically tuned to the frequency channel assigned to the transmitter. The bandpass filter is intended to limit out-of-band emissions at the output of the modulator’s internal amplifier. 2.3.4.4 GPS Receiver The onboard GPS receiver provides accurate, high quality 10 MHz and 1PPS reference signals for transmitter synchronization and has the capability to track 12 satellites. The 10 MHz and 1PPS reference signals are provided for the modulator board as well as one 10 MHz and one 1 PPS reference signal for external devices. The GPS receiver supports the NMEA formatted message protocol as well as the proprietary NavMan binary messages. A subset of the protocols is used by the processor in order to control the receiver. The user has the option to set the Max GPS Holdover time, updated the system clock from the GPS and set the time zone. Following a loss of signal lock (to the GPS satellite network), the Max GPS Holdover time is the maximum length of time the system will continue to operate in a free-running mode before an alarm is issued. 2.3.4.5 I/O Extension Board The I/O extension board provides four (4) analog pull down inputs and four (4) analog pull up inputs, which are available on the rear panel I/O port. The analog inputs are monitored by the system controller permitting the user to set the polarity and voltage threshold that trigger an alarm. NOTE: For this application, Pin 6 has been connected to the cabinet door switch contacts, Pin 7 has been connected to the cabinet smoke detector and the Web interface has been configured accordingly. 2.3.4.6 Transmitter Controller Module • Provides all primary site control and management functionality. • Manages all control interfaces of the transmitter. The modulator and HPA are connected by a RS-485 serial cable for control and monitoring (see Figure 2-6). The system controller supports transmitter operation, configuration, management and status reporting. The control includes power up, power down, RF control processes, control commands for status requests and operating parameters, etc. The transmitter identity (name, password, local IP address, SNMP, etc.) can be configured remotely or locally. Remote upgrade of the transmitter software is supported. The system controller supports a web interface (Web GUI) for its user interface and is responsible for software and configuration management. Remote control of the transmitter is typically managed via an SNMP agent.

CL1TC-4 400W DVB-H Transmitter Product Description Product Manual, Rev. 1 18 2.3.5 High Power Amplifier (HPA) • The module provides RF signal amplification up to the required 400 Watts output power level at the HPA RF output. • The output power level is maintained via an ALC loop. • The output forward and reverse power levels are measured by the integrated output coupler and reported to the system controller. The main system diagram for the High Power Amplifier (HPA) is shown in Figure 2-8. This compact design employs a high efficiency LDMOS technology with a 400 Watt power rating. The HPA includes a LCD display for status messages. The HPA also includes two power supplies and has two variable speed DC fans for forced air cooling. The HPA is designed to operate as a final amplification stage for the terrestrial L-Band transmitter system. It amplifies the L-Band terrestrial signal from the modulator up to a power level of 400 Watts, while maintaining acceptable output emission levels. The HPA is a field-replaceable system component that includes integrated AC/DC power supplies. The HPA is designed for installation in an indoor or environmentally protected outdoor cabinet. The HPA architecture is based on a solid state design operating in the Class A/AB linear mode over a frequency range from 1670 MHz to 1675MHz. The amplifier is fully protected against input overdrive, overheating and output load VSWR conditions. The protection circuits are all self-correcting, allowing restoration of the amplifier to the normal operational state upon removal of the fault condition. The HPA incorporates an internal automatic self-leveling loop to maintain a constant output power level. The automatic level control (ALC) circuit will compensate for the input signal level variations and gain variations affected by changes in temperature as well as for the gain change due to devices aging. The HPA main driver chain signal is split and feeds six individual LDMOS power modules. The output of each module is combined and fed into the combiner/coupler which includes a RF monitor port and RF detectors to measure forward and reflected power levels. The HPA controller monitors the operation parameters of the HPA, provides protection against abnormal operation conditions and communicates with the modulator system controller via a RS-485 serial link. There are six output power modules in parallel configuration in the 400W DVB-H HPA. The rated output power level of the HPA during normal operation is 56 dBm (400W). In the event of a partial failure (the lowest current reading on one of the power modules is less than 20% of the highest current reading on one of the power modules), the HPA is capable of operating with a maximum output power level of 53 dBm. If the output power level is greater than 53 dBm, it will be automatically reduced to 53 dBm. If the output power level is less than 53 dBm, no reduction will occur.

CL1TC-4 400W DVB-H Transmitter Product Description Product Manual, Rev. 1 20 2.3.5.1 HPA Enhanced Features and Design Concepts The HPA utilizes several innovative features designed to enhance its performance and reliability of the amplifier. • Enhanced Heat Sink Design • Thermally Enhanced Power Transistors • Variable speed (temperature controlled) DC fans The HPA employs a heat sink design that permits more equal heat distribution across the heat sink, thus reducing the maximum operating temperature. Distribution of the main heat source elements within the HPA is optimized in order to utilize the maximum thermal efficiency from the heat sink, also resulting in lower operating temperatures. The HPA design incorporates the latest generation high power LDMOS transistors which employ a thermally enhanced package. The significant reduction in thermal resistance will allow these new generation power devices to operate with a lower junction temperature thus improving overall amplifier reliability. The variable speed fans allow the fan speed to be increased or decreased as the HPA temperature increases or decreases. This improves overall efficiency of the HPA and the lifetime of the fans. 2.3.5.2 HPA Controller The HPA embedded controller monitors all operating parameters and provides amplifier protection and control. It communicates with the main system controller via the RS485 interface and reports the following parameters and statuses: • HPA input power level • HPA forward power level • HPA reflected power level • HPA power supply DC voltage levels • HPA pre-driver, driver and power module current consumption • HPA temperature • HPA fan speed • HPA RF power inhibit • HPA input overdrive alarm • HPA output overdrive alarm • HPA output reflected power (VSWR) alarm • HPA failure alarm • Over-temperature fault • Pre-drive and driver device (current) fault • Power module current misbalance fault (results is output power limitation) • Power module device (current) fault • Power Supply DC Fault • Fan stalled alarm
CL1TC-4 400W DVB-H Transmitter Product Description Product Manual, Rev. 1 21 The following HPA factory control commands are available via USB: • RF Power enable/disable • Attenuator control The HPA is a constant gain block, which is individually calibrated in order to maintain the RF performance while operating in various conditions. The calibration is performed on the forward power sensor, reflected power sensor and input power sensor. A calibration table is stored in the internal EEPROM of the HPA controller. The HPA controller reports alarms to the system controller and maintains an internal log of alarms. Each alarm entry in this log contains the alarm ID itself along with monitored parameters prior to an alarm. This alarm log is saved in an internal EEPROM. 2.4 Breaker Panels The two (2) breaker panels are mounted on the left wall of the cabinet (when looking at the front of the cabinet) in the top-left corner of the wall. Circuit breaker panel 1 receives the input AC power and distributes the required power to circuit breaker panel 2, as well as the air conditioner. Circuit breaker panel 2 receives AC power (from circuit breaker panel 1) and distributes the required power two (2) receptacles as well as the HPA. One of the receptacle provides AC power to the UPS, internal lights and smoke detector; the other is a GFI. 2.5 Control Interfaces The modulator serves as the primary system controller responsible for configuration and management of the entire transmitter and interfaces. The physical interface for system management is the modulator Ethernet port, which supports Web, SNMP v3 (secure SNMP), and Telnet. The modulator hosts an internal web interface (Web-GUI) accessible through its Ethernet management port. The Web-GUI is an intuitive interface allowing the user to access the current transmitter status and configure the operational parameters of the system. The Web interface uses a simple hierarchical menu structure which provides access to all transmitter parameters. Below is a snapshot of the main status screen of the Web-GUI. The transmitter SNMP interface provides the means for remote management of the transmitter 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 logs are available via the SNMP interface and are stored in Non Volatile Memory

CL1TC-4 400W DVB-H Transmitter Commissioning and Operation Product Manual, Rev. 1 42 5.3.3 Turning On the RF Output 1. Check the Alarm Status screen for active alarms. The only alarm present should be GPS Quality Low. The GPS Quality Low alarm will take up to 5 minutes to clear as satellites are acquired. 2. During the initial on-site turn on, it is recommended to set the transmitter output level to 46 dBm (minimum value) before the transmitter is placed in Broadcast mode. This will ensure that the effects of a transmission line or antenna fault are minimized when the RF is turned on. Navigate to Config –> HPA Control and set the output power level to 46 dBm – see Figure 5-6. 3. For SFN operation, check the Alarm Status screen to ensure that the GPS Quality Low alarm has cleared. Once the alarm has cleared, the transmitter can be placed in Broadcast mode. Note: For MFN operation, the GPS is not required to be locked. 4. From the HPA Control page, set the Transmitter Operating Mode to Broadcast. 5. The modulator front panel Status Display window “i”, HPA front panel LCD, or Web GUI Global Status page can be used to monitor the transmitter forward and reflected power levels. Alternatively, a power meter can be connected to the HPA sample port to monitor the forward power level. 6. If the forward and reflected power levels are acceptable, increase the RF Output Power Level by 3 db and continue to monitor the forward and reflected power levels. 7. Continue to increase the RF Output Power Level by 3 dB, until the desired output level is reached (max of 56 dBm). Figure 5-6 HPA Control 5.3.4 Turning Off the RF Output Before turning off the AC power switch, the user should set the Transmitter Operating Mode to Standby. This will ensure that the next time the transmitter is powered on, it will be powered on in Standby mode.
CL1TC-4 400W DVB-H Transmitter Commissioning and Operation Product Manual, Rev. 1 43 5.4 Control and Communication The Transmitter can be controlled and monitored locally (on-site), or remotely from a Network Management System (NMS). 5.4.1 Control and Communication Interfaces There are two interfaces port provided for control and communication: • Ethernet Port A or B (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) telnet session is the supported protocol. For a detailed description of the Web-GUI interface refer to Section 6. For a detailed description of the CLI interface refer to Section 7. 5.4.2 Local Access The transmitter can be controlled and monitored locally (on site) through Ethernet Port A or B and/or the USB port with a PC. The modulator front panel LCD and cursor/execute keys can also be used for local access. The Ethernet ports provide access to the Web GUI and CLI (through Telnet). The USB interface provides access to the CLI, which allows the operator to perform initial setup/troubleshooting when network connectivity is not available or desired. 5.4.3 Remote Access The Network Management System (NMS) operator can control and monitor the transmitter remotely through Ethernet Port A or B and LAN using the Web GUI and/or SNMP interfaces. 5.5 Modes of Operation There are two main parameter groups which determine the operating mode, the Transmitter Operating Mode parameter group and the Modulator Operating Mode parameter group. 5.5.1 Transmitter Operating Modes The chief transmitter operating modes are Broadcast and Standby. If the transmitter experiences an AC power interruption under normal, no fault conditions, the transmitter’s AC power-up algorithm will restore the mode of operation that was active prior to the AC power interruption, once power is restored.
CL1TC-4 400W DVB-H Transmitter Commissioning and Operation Product Manual, Rev. 1 44 5.5.1.1 Broadcast Mode The transmitter normally operates in broadcast mode, allowing it to transmit a broadcast signal and run all protection loops and ALC. It receives a transport stream signal, or generates an internal test signal and transmits an OFDM signal for terrestrial broadcast. In this mode, all transmitter functions are automatically maintained by the modulator controller. To operate in broadcast mode, the following conditions must be met: • The transmitter must be receiving an input signal and be locked to the input stream (if the modulator is in test mode, the input signal presence is ignored). • The ALC loop must be running. • For Single Frequency Network (SFN) operation, the system must have a GPS signal lock with no alarms (if the modulator is in test mode, the GPS signal presence is ignored). • There must be no modulator alarms. • There must be no HPA alarms. 5.5.1.2 Standby Mode In this mode the transmitter output is muted by turning the HPA RF switch off and muting the modulator output. The operating conditions in Standby Mode are: • AC power is supplied to the modulator and HPA • The HPA RF switch is off • The modulator output is muted 5.5.2 Modulator Operating Modes The five modulator modes are: Normal, CW, Test 1 (Carriers Removed), Record and Playback. In Normal mode, the modulator generates a complete DVB-H waveform. CW and Test 1 are special test modes not used in regular operation. The CW mode generates a narrow-band frequency tone and the Test 1 mode suppresses a set of OFDM carriers in the center of the band (useful for checking for interference, factory configurable). Record and Playback are described in Section 6.4.1. 5.6 Indicators and Controls The transmitter main subassemblies have individual indicators and controls used in normal operation. This includes: • DVB-H Modulator • HPA

CL1TC-4 400W DVB-H Transmitter WEB Interface Product Manual, Rev. 1 56 6.3.2 GPS Status The GPS Status page provides access to GPS receiver information including the lock status and the number of visible satellites, as well as the exact location and time. • GPS Common: Indicates the GPS PLL Status (Lock or Unlock), Position Altitude, Position Latitude, Position Longitude, 3D Fix, Number of Visible and Tracked Satellites, and Sigma Accuracy. GPS Common will also indicate if the System Clock is updated from the GPS and it will display the System Timezone. • Satellites: Indicates the satellite number and corresponding carrier to noise ratio. Figure 6-7 GPS Status After initialization, the GPS starts tracking the satellites to determine its position; the accuracy of the GPS output signals depends on the GPS satellite reception. The GPS PLL Status will indicate “Lock” when the quality of the received GPS signals are higher than the minimum reception level and the minimum number of tracked satellites is reached. GPS 3D Fix will occur when a minimum of 4 satellites are tracked. The GPS will then display Position Latitude, Longitude and Altitude. The output of the GPS (1 PPS and 10 MHz pulses) is fed to the Distribution Amplifiers, which in turn feed the pulses to the modulator and up-converter. The Controller communicates continuously with the GPS to deter-mine if the GPS is still operating correctly and still receiving the satellite signals, etc., or if it has any alarm (malfunction) to report. A PLL (Phase Locked Loop) Status Unlocked event can be the result of an antenna under-current (antenna open) or antenna over-current (short), a poor GPS 3D Fix (minimum requirement is 4 satellites). In general, conditions that result in a poor GPS signal quality.

CL1TC-4 400W DVB-H Transmitter WEB Interface Product Manual, Rev. 1 59 6.4.1 Modulator Mode This page allows the users to select the Modulator Mode and the Test Mode. Figure 6-10 Modulator Mode Configuration The available parameters are: Item Option Modulator Mode Normal, CW, Test1 (Carriers Removal), Record , Playback Table 6-2 Modulator Mode Parameters CW and Test 1 are special test modes not used in regular operation. The CW mode generates a narrow-band frequency tone. This is useful for phase noise measurements or to view background noise. The Test 1 mode suppresses a subset of the carriers from the center of the DVB-H signal. This is useful for simulating a notch fading event or to view the background noise present in the band. In the “Test 1” mode, usually 500 carriers are removed. The number of removed carriers can be factory configured from between 100 to 800 via the advanced access interface. The Record mode allows the user to record a input data stream (limit of 16 megabytes) for later playback. The modulator must first be set to SFN mode, a valid SFN input stream must be present and no input stream alarms can be reported. After recording, the modulator will automatically switch back to Normal mode. The user can check the Global Status page to see that the modulator is back in Normal mode and that the stream has been recorded. The user can check also the “List Uploaded Files” screen under “System Parameters” to see the file name displayed. In the Playback mode the recorded input stream is used to generate a modulator output. This is useful for detailed system testing especially when an input signal is not available or for benchmark testing using a known test signal.
CL1TC-4 400W DVB-H Transmitter WEB Interface Product Manual, Rev. 1 60 6.4.2 Transmission The Transmission page allows the user to select the network type (MFN or SFN), set the modulation parameters and configure a number of SFN parameters. The Transmission page will change dynamically, depending on the Modulator Mode selected (MFN, SFN or SFN with Config From Stream On). The user has the option to configure the modulation parameters from the incoming stream (MIP) or locally. In SFN mode, a network of modulator operating at the same frequency are all synchronized using special timing packets (MIP) embedded in the input transport stream as well as GPS timing information. If the SFN mode is disabled, the system will operate in MFN mode where all modulators in a network work independently of one another. Figure 6-11 Transmission Configuration (MFN)

Standby mode disables the transmitter output. In Manual mode the HPA behaves as a simple amplifier and the modulator control of the HPA output is limited to setting the input drive level to the HPA. The RF Output Power Level allows the user to set the output power level to a value between 46 dBm and 56 dBm.
