THEORY OF OPERATION: Control Board Assembly Power Supplies: Power is supplied through J1. Pins 1 and 2 are +12 volts; pins 3 and 4 are ground. Ferrite beads are used on all connections on J1 to minimize RF leakage to the power lines. C1 and C2 provide additional RF fil te ring of t he 12 volts before it passes through D1, which provides reverse polarity protection for the transmitter. Filter capacitors are used on the inputs and outputs of the regulators to prevent unwanted oscillations. U2 is a fixed +5 volt regulator used primarily for the logic and prescaler circuits. U1 is a fixed +8 volt regulator used for the audio, video circuits and miscellaneous operational amplifiers. Q2, 5, 6, and R8-15 form a variable voltage regulator for the driver FET that is adjusted by R14 for proper drive levels to the final amplifier. Q1, 3, 4 and R2-6 form a variable voltage regulator for the final amplifier. R16- 20 and S1 are placed in the feedback portion of the regulator to provide a selectable voltage output to the PA. Selection of the voltage applied to the final amplifier allows different power levels to be achieved. R19 sets power output to 12 Watt while R20 sets the output power to 2 Watts. R37-40, 51, C36-40, C95, and U5 Generates the negative 2-volt bias required for the FET’s on the PA. Q7 and Q8 disable the variable voltage regulators to prevent power from being applied to the PA until the PLL provides a lock detect condition. R44 and C27 remove the narrow pulses originating from the lock detect output of U6 pin 28. Video circuits: Video is connected through J2 to the 525-line video pre-emphasis network of R22-26, C12, and L1. R25 allows for the adjustment of the network due to tolerance deviation of components. This network also forms a 75-ohm termination for the video. D4 and D5 provide deviation limiting. R28 adjusts video deviation of the transmitter. C11 and C13 remove the D.C. component of the video signal. Audio circuits: Audio for sub-carrier 1 is connected through pins 6 (high) and 7 (low) of J1 to T1, which is configured as a 600-ohm balanced coupling transformer. The output of T1 is terminated with R79 and A.C. coupled to U7 by C48. U7 is a dual gain control circuit. Channel 1(pins 1,2,3,5,6,7,8) is configured to amplify the audio while channel 2 (pins 9,10,11,12,14,15,16) acts as a limiter and provides a 2: 1 compression of the audio signal. R62-64, C59-61 and Q11 form a three pole 10 KHz low-pass filter. R65 is used to adjust the deviation of the sub-carrier. R66-70, C62-65, L2, D8, and Q12 form a series tuned colpitts oscillator. L2 is a variable inductor for tuning the frequency of the oscillator. Sub-carrier frequencies available are 4.83Mhz, 5.8Mhz, 6.2Mhz, 6.8Mhz and 7.5Mhz. C62 couples the audio to the oscillator. D8 is the varactor diode, which modulates the sub carrier. Q13 is a buffer amplifier and L3 and C67 provides tuning (peaking) for the amplifier. R74 is used to adjust the sub- carrier insertion level. THEORY OF OPERATION: Control Board Assembly Audio circuits: Audio for sub-carrier 2 is connected through pins 8 (high) and 9 (low) of J1 to T2, which is configured as a 600-ohm balanced coupling transformer. The output of T2 is terminated with R78 and A.C. coupled to U8 by C71. U8 is a dual gain control circuit. Channel 1(pins 1,2,3,5,6,7,8) is configured to amplify the audio while channel 2 (pins 9,10,11,12,14,15,16) acts as a limiter and provides a 2: 1 compression of the audio signal. R86-88, C82-84 and Q14 form a three pole 10 KHz low-pass filter. R89 is used to adjust the deviation of the sub-carrier. R90-94, C85-88, L4, D9, and Q15 form a series tuned colpitts oscillator. L2 is a variable inductor for tuning the frequency of the oscillator. Sub-carrier frequencies available are 4.83Mhz, 5.8Mhz, 6.2Mhz, 6.8Mhz and 7.5Mhz. C85 couples the audio to the oscillator. D9 is the varactor diode, which modulates the sub carrier. Q16 is a buffer amplifier and L5 and C90 provides tuning (peaking) for the amplifier. R98 is used to adjust the sub- carrier insertion level. PLL circuits: PLL IC: It is beyond the scope of this document to discuss the theory of Phase Locked Loop design only the support circuits and operation will be detailed. U6 is a low frequency CMOS PLL. It contains a reference oscillator, selectable-reference divider, two output phase detector, 10-bit programmable divide-by-N counter, 6-bit programmable divide-by-A counter, dual modulus controller, and a lock detect circuit. If combined with a VCO, dual modulus, and loop filter, then frequency synthesis up to the devices frequency limit can be achieved. Tron-Tek, Inc. equipment also incorporates a Micro-Controller to allow operation only within the user designated frequencies of 1990- 2110, 2025-2135 and 2450-2499. Additionally this equipment utilizes an external temperature compensated reference oscillator (TCXO). VCO: See VCO section for description. Dual Modulus: U4 is a Dual Modulus which divides the VCO frequency by 64 or 65 depending on the status of the A counter within U6. Control of the divide ratio is provided by U6 pin 9. R36 provides proper input load. C28 A.C. couples the VCO frequency into U4. R53 provides an output load while C34 A.C. couples the output of U4 into the U6 Pin 1. The A and N counter then divide this frequency and present it to the phase detector for comparison to the reference frequency. C31-33 and C35 provide de-coupling for U4. THEORY OF OPERATION: Control Board Assembly PLL circuits: Loop Filter/Buffer: R45-50, C17-25, and U3 form the low pass loop filter. This filter removes the narrow pulses inherent in the phase detector and provides a loop error signal. The video, audio and loop filter signals are summed at the base of Q9, which buffers this signal. R35 provides a load for the buffer and R34 decouples the high frequency of the VCO while coupling the control voltage to the VCO. TCXO: R41, R43, R52, R100, C42, C43, Q10, Y1, and C45-47 form a 16MHz oscillator. C47 and R5…

AMENDED December 8, 2000 NAME OF TEST: Field Strength of Spurious Radiation SPECIFICATION: 47 CFR 2.1053(a) GUIDE: ANSI/TIA/EIA-603-1992, Paragraph 1.2.12 MEASUREMENT PROCEDURE 1.2.12.1 Definition: Radiated spurious emissions are emissions from the equipment when transmitting into a non-radiating load on a frequency or frequencies which are outside an occupied band sufficient to ensure transmission of information of required quality for the class of communications desired. 1.2.12.2 Method of Measurement A) Connect the equipment as illustrated B) Adjust the spectrum analyzer for the following settings: 1) Resolution Bandwidth≤3 kHz. 2) Video Bandwidth≥10 kHz 3) Sweep Speed≤2000 Hz/second 4) Detector Mode = Positive Peak C) Place the transmitter to be tested on the turntable in the standard test site. The transmitter is transmitting into a non-radiating load which is placed on the turntable. The RF cable to this load should be of minimum length. FCC ID: IZ3-TT-2012TS-AB MFA p0050013, d0080049 PAGE NO.14 of 30. AMENDED December 8, 2000 NAME OF TEST: Field Strength of Spurious Radiation (Cont.) D) For each spurious measurement the test antenna should be adjusted to the correct length for the frequency involved. This length may be determined from a calibration ruler supplied with the equipment. Measurements shall be made from the lowest radio frequency generated in the equipment to the tenth harmonic of the carrier, except for the region close to the carrier equal to±the test bandwidth (see section 1.3.4.4). E) For each spurious frequency, raise and lower the test antenna from1mto4mtoobtain a maximum reading on the spectrum analyzer with the test antenna at horizontal polarity. Repeat this procedure to obtain the highest possible reading. Record this maximum reading. F) Repeat step E) for each spurious frequency with the test antenna polarized vertically. G) Reconnect the equipment as illustrated. H) Keep the spectrum analyzer adjusted as in step B). I) Remove the transmitter and replace it with a substitution antenna (the antenna should be half-wavelength for each frequency involved). The center of the substitution antenna should be approximately at the same location as the center of the transmitter. At lower frequencies, where the substitution antenna is very long, this will be impossible to achieve when the antenna is polarized vertically. In such case the lower end of the antenna should be 0.3 m above the ground. FCC ID: IZ3-TT-2012TS-AB MFA p0050013, d0080049 PAGE NO.14.2 of 30. AMENDED December 8, 2000 NAME OF TEST: Field Strength of Spurious Radiation (Cont.) J) Feed the substitution antenna at the transmitter end with a signal generator connected to the antenna by means of a non- radiating cable. With the antennas at both ends horizontally polarized and with the signal generator tuned to a particular spurious frequency, raise and lower the test antenna to obtain a maximum reading at the spectrum analyzer. Adjust the level of the signal generator output until the previously recorded maximum reading for this set of conditions is obtained. This should be done carefully repeating the adjustment of the test antenna and generator output. K) Repeat step J) with both antennas vertically polarized for each spurious frequency. L) Calculate power in dBm into a reference ideal half-wave dipole antenna by reducing the readings obtained in steps J) and K) by the power loss in the cable between the generator and the antenna and further corrected for the gain of the substitution antenna used relative to an ideal half-wave dipole antenna. M) The levels recorded in step L) are absolute levels of radiated spurious emissions in dBm. The radiated spurious emissions in dB can be calculated by the following: Radiated spurious emissions dB = 10log 10 (TX power in watts/0.001) – the levels in step l) NOTE: It is permissible that other antennas provided can be referenced to a dipole.
