ATSC 1KW DTV TX User Manual Version 1.6 02/12/2014 Page 16 of 47 7 Theory of Operation The ATSC 1000W DTV transmitter is conceptually simple to understand and easy to operate. The Transmitter operates on 3-phase 220V, 30A AC Mains service. An AC Mains Distribution compartment is located in the back rear floor of the TX. This compartment is shielded for personnel safety and provides the distribution of appropriate AC power to the various modules inside the TX cabinet. A standard ATSC ASI input stream is provided to one of the BNC connectors located on the rear panel of the Exciter. The Exciter supports options for DVB-ASI and SMPTE310M stream formats as well as an RF off-air input via a built-in tuner and TSoIP support via an RJ-45 input. The Exciter performs the appropriate FEC and Signal Processing to modulate a standard 19.39 Mbps ATSC TS to produce an RF output at the desired channel frequency. Supported ATSC modulation standards include A/53 (Legacy), A/153 (MH), and A110:20011 (SFN). The TX supports both Single and Dual Drive (DD) Exciter configurations, and manages the automatic and manual switchover between Exciters in a DD configuration. The modulated RF output signal from the Exciter(s) is(are) fed into the Control module which contains a 50W preamp driver (1xBLF571 device driving 2xBLF881 transistors in parallel). The output of the Controller preamp is then split and fed to the RF inputs of each of the PA modules. The PA modules contain 4x BLF888A devices that amplify the RF signal to produce 600W of output power per PA. The amplified output signals of the two PAs are fed into a 2-way Hybrid Combiner and then into a Directional Coupler and finally out the top of the cabinet via a section of 1 5/8 transmission line. The 1 5/8 output stack of the Transmitter is then fed into an inline 1 5/8 Harmonic Filter (if required) before entering a channel mask BPF. The output of the BPF connects to the Antenna feed to radiate the DTV signal on-air. The Exciter receives two feedback signals from FWD and REV couplers located on the BPF. These before and after BPF feedback signals are used by the Exciter to provide automatic Linear and Non-Linear pre-correction of the ideal 8-VSB forward path signal. Additional feedback signals are provided to the Control module, which monitors these samples to implement protective protocols including forward power reduction and shutting down the TX in the event of high reflected power or other unsafe operating conditions. System FWD and REV power samples are provided to the Control module from the Directional Coupler located directly after the 2-way power combiner. The Control module also receives a feedback sample from the Reject Load, enabling it to control the variable fan speed on the load.
ATSC 1KW DTV TX User Manual Version 1.6 02/12/2014 Page 17 of 47 The Control module is in constant communication with the Exciter and PA modules via an RS-485 serial bus. Each module has a unique ID on the bus, and the Control module is continually talking with the Exciter and PA modules to provide monitoring and control capabilities via its front panel touchscreen and built-in web user interfaces. Both the Control module and the Exciter provide RJ-45 Ethernet connections through which the user may remotely monitor and control the TX via their respective built-in web interfaces.
ATSC 1KW DTV TX User Manual Version 1.6 02/12/2014 Page 18 of 47 8 Quick Start Guide – to safely turning on your Transmitter 1 After unpacking, inspecting, and installing the transmitter components, connect all the cables as per the interconnect diagram inside the transmitter. Install and connect the Band Pass Filter. Install and connect the Band Pass Filter monitoring cables between the Band Pass Filter “N” Type connectors and their respective transmitter connections on the top of the transmitter cabinet. 2 Connect the antenna or a suitable station load BEFORE continuing any further. 3 Install and connect the 220-volt power cable to the terminal block located inside the AC Mains Distribution compartment on the floor of the transmitter. Connect the cable to the station power source. 4 Ensure all power switches and breakers are turned off on the front of the transmitter cabinet, and on the Power Amplifiers, Exciters, and Controller. 5 Apply power to the transmitter by energizing the AC mains to the transmitter. Turn on the breaker on the bottom front of the transmitter. Ensure that the AC Mains indication is illuminated. 6 Although the transmitter has fully been tested and calibrated at the factory, the major operating parameters should now be checked before attempting to make power with the transmitter. To do this, turn on the exciters ONLY and allow them to initialize. 7 Verify the operating frequency of the exciters by pressing the right arrow navigation button on each exciter to indicate the second status screen of the exciter. You should see an indication of the operating frequency in the following format: FREQ:605. This example indicates that the operating frequency would be set for a center frequency of 605Mhz. 8 If the operating frequency is incorrect, navigate to the Frequency Setting menu by pressing the Exciter LEFT and RIGHT navigation arrows simultaneously. Then move the cursor (shown as an asterisk *beside the current selection) to the Freq Menu then press enter. Disregard the RX Frequency for Transmitter operation as this is used for Translator Operations only. Move the cursor to the TX Frequency and select the correct frequency by using the UP or DOWN arrows. Once the correct frequency is selected, press the ENTER button to initiate the frequency change. Repeat this procedure for the remaining exciter. 9 Press the ESC button once. Move the cursor to the RF menu, press enter. Make a note of the exciter RF POWER output level (this level is typically somewhere between -6 and 0dB). Make sure that the Exciter AGC is turned OFF. Do this for the remaining exciter as well. 10 Connect the ASI transport stream to each exciter using the TS-1A input if ASI is being used. Use TS-2A input if SMPT-310M is being used (ACT-8X model). Verify that the corresponding TS 1 or TS 2 LED is illuminated on the front of the exciter that corresponds with the input group used. 11 Navigate to the Exciter RF submenu and turn RF ON. Do this for both exciters and verify that both exciters have the RF ON LED illuminated. 12 Power on the amplifier assemblies by turning on the breakers located on the rear of the assemblies, and the controller via the power switch located on the rear of the unit, in that order. 13 Locate the touch screen display on the TX Control Module. Find the red button on the main screen (this in the TX ON button). Press this button to turn the TX ON. The button will turn GREEN when the Controller turns On the transmitter.
ATSC 1KW DTV TX User Manual Version 1.6 02/12/2014 Page 19 of 47 14 Allow 45 to 50 seconds for the transmitter to ramp up power. The Controller will indicate output power in Watts in real time. 15 Allow 15 minutes of operation for the transmitter to warm up. Check operation parameters by viewing the main status screen of the on-air exciter for TSNR, LIMD, and UIMD. 16 For Dual Drive TX configurations, test the Exciter switchover behavior by pressing the A/B icon on the Controller touchscreen and initiating an Exciter Changeover by selecting EXCITER B, and confirming the changeover when asked. The power will drop and the exciter changeover will initiate. Once again, allow 45 to 50 seconds for the transmitter to reach operating power. Make the same performance checks as just outlined for Exciter A. 17 If additional Pre-Correction is needed, refer to the Anywave 1Kw Correction Procedure.

Press the “Amplifier” graphic to navigate to the home Amplifier Status Screens (shown below).
ATSC 1KW DTV TX User Manual Version 1.6 02/12/2014 Page 22 of 47 a) Dual Exciters - Switching Screen: As mentioned above, pressing the “Exc A/B” icon will bring you to the Dual Exciters Switching Screen, as shown below.  Manual Exciter Switchover: Exciter A is the default on-air exciter. The on-air exciter’s status will be “GREEN”, as shown in the screen above, indicating that Exciter B is the current on-air exciter. Pressing the “Exciter A” or “Exciter B” button on this screen will cause a manual switch between exciters, that is if the Controller is “linked” to both exciters. (Note: In a dual drive configuration, both exciters are on at the same time, producing an RF output signal a the same time, and the Controller is considered “linked” with an exciter when the Controller detects an RF output present from the exciter as monitored inside the controller).  Auto Exciter Switchover: In a Dual Drive configuration, the TX is set to auotmatically switch to the standby exciter in the event a problem occurs with the on-air exciter. The TX will not automatically switch back to the original Exciter as long as the standby Exciter is operating properly. However, the TX will automatically switch back to the original Exciter in the event of a problem with the on-air (standby) exciter. So the TX will continue to automatically switch indefinitiely in the event of a problem with the on-air exciter.
ATSC 1KW DTV TX User Manual Version 1.6 02/12/2014 Page 23 of 47  If neither of the exciters can be linked successfully (i.e. the Controller does not detect a valid RF ouptut present from either exciter), a window will pop up, indicating “No Exciter Linked”, as shown below.  If the manual switching is successful, a window will pop up indicating “Change succeed!”, as shown below.

This Control Module interface may be used for a variety of things, including turning the TX On/Off, manually switching between exciters (in a DD configuration), monitoring the voltages and currents of the PAs, etc. A built-in web interface also exists in the Exciter that may be used for such things as adjusting the TX output power, performing corrections, etc. (please reference the separate Exciter User Manual for a detailed description of the Exciter web interace). The Control Module communicates with the Exciter(s) and PAs inside the TX via an RS-485 bus network.
