Prior to equipment turn-on,verify that all appropriate cabling has been accomplished.Turn on1. Ensure the rear mounted main power ON/OFF switch is in the OFF position.2. Insert the power plug into a power outlet.3. Position the main power switch to ON.4. The front panel LED will continuously illuminate green verifying successful turn on and normal operation:OperationSelecting the proper operating channel, as discussed below, and having proper interconnections established betweenthis drawer and all accompanying chassis’ enables operation.Channel Selection / Programming:Channel selection is accomplished in two ways, manually or automatically. Both methods are describedbelow.Manual Channel SelectionManual channel selection is done through the use of the front panel thumbwheel switch. The thumbwheelinterfaces with and EPROM board sending a binary coded decimal (BCD) address to the firmware locatedon the board. The EPROM logic then forwards programming information to the synthesizer in the samemanner. Typical programming results in selection of the lowest channel when the thumbwheel switch isrotated to the [01] position. Progression allows channel selection to move upward in 6 MHz1 steps.Agile Controller InterfaceUpon connection of the Agile Controller, the manual channel setting is overridden. A data ‘Y’ is providedon the DC insertion board. This allows a loop though of logic information in the drawer to the RFprecorrector module located in the upconverter plug-in module. The CPU interface sends a BCD address tothe EPROM board containing the channel selection of the transmitter to be backed up. The EPROM boardthen forwards this programming to the synthesizer module. 1 Channel mapping of A1, B1, A2, B2 ….. G4 is typical, international standards are available.

It consists of a synthesizer, power supply, EPROM board,precorrector board, DC inserter/power distribution board, circulator, and splitter.It receives a 10 MHz frequency reference signal via the rear panel, which is used as the time base for phase lockingthe internal synthesizer. The reference signal is routed through the DC inserter board and the signal is split andamplified by hybrid amplifiers. A conditioned reference signal that contains a DC component containinginformation about the phase lock status of the synthesizer is returned to the rear panel.The reference signal is then superimposed onto a DC logic level; a logic high represents a phase locked condition,while a logic low indicates an “out of lock state”1. A loop through allows the transmitter to utilize the referencesignal for other PLL circuits. Refer to the appropriate sections of the accompanying transmitter manual for detailedinformation.2.FRONT AND REAR PANEL DESCRIPTIONSFront panel:1.

It also provides for an optional saw filter stage, which can be added or bypassed through useof jumpers. This module is used to correct linear distortion within the transmission system.Once inside the incoming signal is split anddirected in two separate paths, one side of thesplitter is sent to a variable attenuator thatadjusts the signal level through the module theother is sent to the detector stage. The inputattenuator provides approximately 15dB ofadjustment range. Through use of an externalmicroprocessor and automatic level controlcan be achieved by varying the inputattenuator, this mode of operation can beselected via the front panel of the module ifthe system is so equipped. Each group delaycell provides approximately ±10ns of delay.These individual stages can be added asneeded to compensate any distortion up to25ns within the system. Adding a stage isaccomplished by moving a pair of jumpers onthe processors main board. Refer to theattached diagram for jumper configurationinformation. Along with delay, the frequencyresponse of the system can be adjustedthrough the frequency response network.Figure 1: IF linear processor, 05-065-02 shown.This network can provide ±.5 dB of frequency response compensation. This stage can be set to make up for afrequency tilt in the system or can be set to counteract the roll-off encountered by the channel filter. Setting the overallbandwidth of the stage is accomplished by adjusting the two variable inductors, which make up the tank circuit in eachfrequency response cell. The gain of each frequency response cell is adjustable via the potentiometer on the front panelof the module. The user is able to select the detection mode of the module. It is able to detect either the incomingsignal or the outgoing signal. The user must set the appropriate jumper on the main board. Regardless of the detectionmode the unused port must be terminated. The detector’s threshold must be calibrated via the front panel adjustment,typically the signal level detector should indicate a module failure if signal is detected at –4dB lower than nominalinput. A TTL logic level is used to indicate module status, a logic high shows signal presence, while a logic low showslow signal level. Another feature of the module is the auxiliary input, which allows a second carrier to be introduced, inanalog systems a secondary audio carrier maybe required. This auxiliary input is also adjustable to ensure propercarrier ratio.A final option is available normally used in digital systems; the saw filter is used to clean up out of band interference.Typically used in agile transmission equipment this additional filtering stage reduces the side-lobe regeneration of theincoming signal. In receiver applications it is used to eliminate undesired signals as a result of mixing. Refer to themodule’s block diagram for more detail.

This second IF frequency,when mixed with the LO, produces the desired microwave frequency. The second IF is necessary to make filteringof the microwave LO and other undesired signals manageable in broadband agile systems. The visual and aural TVIF’s are treated separately through the module, each chain providing the necessary filtering to get rid of the imagefrequency and the UHF local oscillator. In the case of digital, the mixing / filtering stages of the aural chain are leftout. Features of the module include adjustable bandpass filters, LO notches, phase lock indication, LO sample, andan adjustable aural carrier level.UHF SYNTHESIZERThe UHF synthesizer board establishes the final output frequency operation of the module. The synthesizer operatesas the local oscillator within the unit. It contains a voltage controlled oscillator (VCO) phase locked to a highstability reference source (10 MHz) achieving a precise output frequency. This signal is heterodyned (mixed) withan intermediate frequency (IF), typically 44 MHz center, to produce the modules output carriers. When the IF ismixed with the LO a sum and difference product will result.The functionality of the synthesizercan be explained starting with thereference input. To achieve 400KHz, a programmed PAL divides the10 MHz source by 25. The 400 KHzsignal forms the reference to thesynthesizer IC. Internal to the IC is aprogrammable divider, which furtherdivides the reference signal, makingthe reference frequency 50 KHz. Thesynthesizer is a control loop that iscontinuously monitoring thefrequency status of the VCO. Figure 1: 09-080-02 UHF upconverter module.Beginning at the VCO, upon turn on, an unknown frequency is coupled to a dual modulous prescaler that divides theincoming frequency by either 64 or 65 depending on the logic level of the modulous control line at that instant intime. Internal to the synthesizer IC there are two divider stages, called “N” & “A”. These dividers are programmedto achieve the desired output frequency of the synthesizer.In an ideal locked condition, both phase detector inputs will equal 50 KHz. If the frequency arriving from the dualmodulous prescaler happens to be higher or lower than the reference port of the phase detector, an error voltage isgenerated by the integrator to pull the VCO back to the desired frequency. The integrator works by comparingenergy levels caused by a change in duty cycle on its inputs. Following the integrator stage is a passive low passfilter; added to further reduce the reference spurs. Eliminating reference noise before it reaches the VCO is vital.The sharp pulses generated by the synthesizer IC can cause unwanted spurious products.THREE POLE UPCONVERTER STAGEThis stage is responsible for translating the TV IF frequency to a 2nd IF at around 350 MHz as stated above. The IFenters the module, it then passes through a lowpass filter stage, then to the mixer. Once the IF and LO areheterodyned, the undesired signals must be filtered. This is accomplished with a three pole filter designed to rejectthe LO and image frequency. A notch is incorporated to further reject the LO

Additionally, the aural carrier may be adjusted in level to set the carrierratio in analog applications.

The operating frequency is determined by programming of the phase locked loop frequencysynthesizer. Agile transmitter programming information is sent via an eprom board, there are no DIP switches.Miniature DIP switches SW1 and SW2 set N counter and A counter PLL programming inputs. A 10 MHz inputreference signal applied to J1 determines the frequency stability of the PLL.The synthesizer module uses a microwave prescaler, dual modulus prescaler, and internal dividers to reduce the 10MHz reference and microwave voltage controlled oscillator (VCO) frequencies to 25 kHz for the 09-049 series and09-093 version; 125 KHz for the 09-073 series, 09-097 & 09-098 versions; or 200 KHz for the 09-092 version.These signals are applied to separate inputs of a phase detector. Input signals of equal phase generate no change inoutput. Should the VCO deviate in frequency, a phase shift is detected causing an integrator/low pass filter togenerate a DC control voltage proportional to the offset frequency. This control voltage is applied to the microwaveVCO to return it to the selected frequency.The microwave local oscillator frequency is derived by adding (or subtracting in certain cases) the desiredtransmitter channel frequency to the incoming IF frequency:EXAMPLE: Visual Output Frequency +Visual IF =Microwave LO Frequency2501.25 MHz +45.75 MHz =2547 MHzAural Output Frequency +Aural IF =Microwave LO Frequency2505.75 MHz +41.25 MHz =2547 MHzFigure 1: Fixed channel synthesizer, 09-073 version.

1Precorrector Calibration Control Board – 34-015COMWAVE DIVISIONAll information contained in this document is confidential and proprietary to THOMCAST and shall not be disclosed without the prior written permission of THOMCAST.CREATED: KAS ................................................................4/20/99 CHECKED: DMW............................................................. 4/20/99RELEASED: CPU............................................................. 4/20/99Document #: DOC13-0130REV: FEB.23.00PRECORRECTOR CALIBRATION CONTROL BOARDThis board provides control of a frequency synthesizer andan RF precorrector. It is typically used in frequency agileequipment. This board may be used to replace various typesof Thomcast EPROM boards.It contains an MC68HC711E9 MCU running a firmwareprogram. The program directs the MCU to set the frequencysynthesizer control data on output connector P4 and to outputthe precorrector analog control voltages on P7 and/or P8. Ingeneral, the synthesizer control data and precorrector analogcontrol voltages will be unique for each broadcast channelavailable to the agile equipment. Therefore, the MCU needsto be aware of the channel that has been selected for the agileequipment. Channel selection is provided as BCD words onP1/P2 and/or P3. The MCU reads the BCD words andprovides the channel-specific outputs accordingly.Connectors P1 and P2 are board logic inputs that aretypically harnessed to the thumbwheel channel selectionswitches on the front panel or top cover of the agileequipment. When the user sets the agile equipment tooperate on a given channel, say channel 18, a combination oflogic ones and zeroes is provided on connectors P1 and P2such that the MCU reads BCD ‘18’ (binary 0001 1000).In cases where a Thomcast Frequency Agile TransmitterControl/Monitor system (Agile Controller) is be connected tothe agile equipment to determine the agile channel in the caseof a system fault, the frequency selection data is input to theboard on connector P5. When the Agile Controller interfaceis connected to P5, P5-5 and P5-6 are grounded, causingswitch ICs U4 and U5 to take the frequency selection datafrom P5 and to apply it to the MCU inputs, whiledisconnecting the thumbwheel switches. The MCU thenselects the appropriate synthesizer control data from itsinternal memory and sends the data to the synthesizer. Figure 1: 34-015-02 board.Precorrector control voltages are typically unique for a channel and are selected for output in the manner describedabove for the synthesizer control. For a given channel, the MCU recalls stored control data for each precorrectorcontrol circuit. The control data for each circuit is written to IC U8, a serial-input 8-channel 8-bit DAC. The MCUwrites the unique control data to each DAC channel, causing analog voltages to be driven out of U8. The analogvoltages are buffered and/or scaled using individual sections of op-amp ICs U9 and U10. Where greater drivecapability is required, transistors Q1 and Q2 are used.Connector P9 and IC U7 provide an RS-232 interface for the board. During factory configuration and testing of theagile equipment, a computer is interfaced to the board. The channel-specific synthesizer control data andprecorrector control data is entered by a technician and stored in the MCU’s internal EEPROM. This data is non-volatile and is not lost when power is removed. Any of the synthesizer or precorrector data may be changed asdesired by connecting the PC and running the setup program.
