System Overview The CHV4TD is made up of the trays/assemblies listed in Table 8-1. Table 8-1. HLV2RD Major Trays and Assemblies MAJOR ASSEMBLY DESIGNATOR TRAY/ASSEMBLY NAME A1 Digital Transmitter (Driver) A2 Amplifier A3 Amplifier 8.4.1 Digital Modulator The modulator accepts an ASTC transport stream in SMPTE 310 or ASI Format input and outputs an 8-VSB RF signal at the desired center frequency. The signal generation function of the modulator is also referred to as the “forward signal path” in this manual. There is also a “reverse signal path” that is used for automatic adaptive equalization. Two transmitter output samples are taken from directional couplers located before and after the channel mask filter and are applied to modulator or the external relay. The modulator contains a down-converter that converts the RF sample to a digital sample. The down-converted sample is digitized by the modulator. It is then demodulated in non-real time software. The result is analyzed to calculate linear and nonlinear adaptive equalizers to improve the transmitted signal quality by compensating for the nonlinear compression of the power amplifier and the linear distortions (mostly group delay effects) of the channel filter. When a linear adaptive equalizer is being calculated the transmitter sample is taken after the channel mask filter so that its linear distortions can be “seen.” When a nonlinear adaptive equalizer is being calculated the transmitter sample is taken before the channel mask filter so that the distortion sidebands being generated by the power amplifier can be seen (the channel filter would remove the out-of-band sidebands). The modulator contains an embedded computer. The computer performs user interface functions and the numerical processing necessary for the adaptive linear and nonlinear equalization. 8.4.2 Digital Transmitter (Driver) The Transmitter Driver provides an On Channel output signal and is used as the pre-driver for the external amplifiers. UBS-Axcera-CLV2TD Equipment Authorization Report Operational Description 8/12/2013 8-3 8.4.2.1 (A5) ALC Board (1315006) The ALC Board of the Innovator CX is used to control the RF drive power to the RF amplifier chain in the HLV2RD. The board accepts a digital RF input signal at a nominal input level of -3 dBm average power and amplifies it to whatever drive level is necessary to drive the final RF amplifier in the tray to full power. The input signal to the board at J1 is split by U4, with one half of the signal driving a PIN diode attenuator, DS1 and DS2, and the other half driving a detector, U13, that is used to mute the PIN attenuator when there is no input signal. The output of the PIN attenuator is sent to two cascaded amplifiers, U2 and U3, which are capable of generating +10 dBm average power from the board at J2. The PIN attenuator is driven by an ALC circuit or by a manual fixed voltage bias, depending on the position of switch S1. When the switch is pointing to the left, looking from the front of the tray, the ALC circuit is enabled. When the switch is pointing to the right, the ALC circuit is disabled and the PIN attenuator is controlled through the Manual gain pot R62. When the switch is in either ALC or manual, the voltage in the unused circuit is preset low by the circuitry connected to pins 4-6 on SW1. This allows the RF power to ramp up slowly to full power when the switch changes positions. CR8, C33 and associated components control the ramp up speed of the manual gain circuit. CR9, C42 and their associated circuits do the same thing for the ALC circui…

PARTS LIST/TUNE-UP INFO 7.1 Parts List The transmitter, can be subdivided as follows: Modulator – RF output ALC Board Output Detector Board Control Card Board Astec multi-voltage supply 35W Amplifier Board Two Stage VHF Amplifier Board Switching Power Supply Amplifier Control board Splitter / Combiner Output metering board System metering board Combiner Mask Filter 7.2 Tune-Up Information This transmitter was aligned at the factory and should not require additional adjustments to achieve normal operation. This transmitter is of a tray design with multiple boards inside the tray. If a board fails, that board needs to be changed out with a replacement board. The failed board can then be sent back for repair. 7.2.1 Set-Up of the Output Power of the Transmitter Check that the Auto/Man switch S1 on the ALC Board is in the Automatic ALC position. Adjust R75 the ALC pot on the ALC Board as needed to attain 100% output power. Switch to Manual Gain (Manual ALC) and adjust the Manual Gain pot R62 for 100 % output power. Switch the ALC Board back to Automatic ALC. 7.2.2 ALC Board Set-Up in the Tray On (A5) the ALC Board (1315006), preset the Overdrive Threshold pot R38 full CW and set R62, Manual Adjust, and R75, ALC Adjust, full CCW. Apply an 8-VSB signal at -3 dBm average level to the J1 input jack to the tray. Switch S1 to Manual Gain, and increase the output power to 100%. Calibrate the transmitter output power using R23, Forward Calibration pot, on the Output Detector Board. Turn the output power down to 10% power. Remove the output RF connector from J2 on tray and calibrate the reflected power to 10%, using R7, the Reflected Calibration pot, on the Output Detector Board. Re-connect the RF output connector to the tray and increase the power, in Manual gain, to 125%. Adjust the Overdrive pot R38, CCW until the overdrive threshold just trips and the Overdrive Fault LED DS4 lights. Turn the pot slightly CW so that power comes back up and DS4 goes out. Switch S1 to ALC. Turn the ALC Adjust pot R75 until the power is 100%. Switch S1 UBS-Axcera-CLV2TD-4 FCC Equipment Authorization Report Parts List/Tune- up Info 8/12/2013 7-2 between ALC and Manual to verify smooth switching, with minimal change in power. Switch the tray Off and insert a 10 dB attenuator at the input. Switch the tray On and verify the input fault LED comes on and the RF power Mutes. Output power should drop by at least 20-30 dB. Switch the tray Off and remove the 10 dB attenuator. Replace the input connector and turn the tray back on. With the tray in ALC, use the ALC Adjust pot, R75, to decrease the power to 10%. Remove the RF output connector from the tray. Verify that the VSWR Cutback LED, DS6, comes on and the Reflected Power drops to approximately 6%. Reconnect the RF output connector and increase the power back up to 100%. This completes the set up of the ALC board. 6 MHz -35 dB -110 dB 3 MHz 6 MHz Figure 3: Typical Digital Spectrum 7.2.3 Linearity Correction Adjustment (Non-Linear Distortions) As shipped, the transmitter was preset to include amplitude and phase pre-distortion. The pre-distortion was adjusted to approximately compensate the corresponding non-linear distortions of the Power Amplifier. All adjustments are made using the Modulator. The transmitter is now set up and ready for normal operation.

Test Equipment Setup for RF Power Measurements The output power of the HLV2RD was adjusted to obtain 1000 watts average RF output as observed on the power meter. Per FCC 2.1046. Measured Power: +10 dBm Coupling Loss: -50.0 dB Power: +60 dBm Power = 1000 Watts With the power level properly set to 1000 watts average, all required tests were performed and recorded in the following sections.

A pilot tone is provided, to allow rapid acquisition of the signal by receivers. The 8-VSB system transmits a serial data bit stream at a rate of 19.4 Mbps in a 6 MHz television channel. This type of transmission is far less susceptible to propagation impairments such as multi-path, noise and interference as compared to analog transmissions. The modulator is fully adaptive to correct linear and nonlinear distortions. Per FCC 2.1047. Figure 4-2.
