FCC ID: K66GX1255S Circuit Description Vertex Standard Co., Ltd. GX1255S GX1255S GX1255S GX1255S Circuit Description Circuit DescriptionCircuit Description Circuit Description Reception and transmission are switched by “RX-CNTL” and “TX-CNTL” lines from the CNTL Unit. The receiver uses double-conversion superheterodyne circuitry, with a 21.4 MHz 1st IF and 450 kHz 2nd IF. The 1st local is produced by a PLL synthesizer, yielding the 21.4 MHz 1st IF. The 2nd local uses a 21.850 MHz crystal oscillator, yielding the 450 kHz 2nd IF. The 2nd mixer and other circuits use a custom IC to convert and amplify the 2nd IF and detect FM to obtain demodulated signals. During transmit, the PLL synthesizer oscillates at the desired frequency directly, for amplification to obtain RF power output. During transmit, voice modulation is applied to this synthesizer. Transceiver functions, such as TX/RX control, PLL synthesizer settings, and channel programming, are controlled using the MPU. Receive ReceiveReceive Receiver Incoming RF signals from the antenna connector are delivered to the RF Unit, and pass through a low-pass filter (LPF) consisting of coils and capacitors, and antenna switching diodes D DD D1003 10031003 1003 and D DD D1004 10041004 1004 (both XB15A308 ) for delivery to the receiver front end. Signals within the frequency range of the transceiver are then passed through a bandpass filter consisting of T1001 and T1002 before RF amplification by Q QQ Q1014 10141014 1014 ( 2SC5006 ). The amplified RF is then bandpass filtered again by T1003, T1004, and T1005, to ensure pure in-band input to 1st mixer Q QQ Q1018 10181018 1018 ( 3SK320 ). Buffered output from the VCO Unit is amplified by Q QQ Q1016 10161016 1016 ( 2SC5006 ) and bandpass filtered by L2012, C1072, and C1078, to provide a pure 1st local signal between 134.65 and 140.625 MHz for delivery to the 1st mixer. The 21.4 MHz 1st mixer product then passes through dual monolithic crystal filter XF2001 (±6.5 kHz BW), and is amplified by Q QQ Q1022 10221022 1022 ( 2SC4400-3 ) and delivered to the input of the FM IF subsystem IC Q QQ Q1024 10241024 1024 ( TA31136FN ). This IC contains the 2nd mixer, 2nd local oscillator, limiter amplifier, FM detector, noise amplifier, and squelch gates. The 2nd local in the IF-IC is produced from crystal X XX X1001 10011001 1001 (21.850 MHz), and the 1st IF is converted to 450 KHz by the 2nd mixer and stripped of unwanted components by ceramic filter CF CFCF CF1001 10011001 1001. After passing through a limiter amplifier, the signal is demodulated by the FM detector. Demodulated receive audio from the IF-IC is amplified by Q QQ Q1025 10251025 1025 ( 2SC4154E ), then the signal is through the AF Mute switch Q QQ Q1027 10271027 1027 ( TC4S66F ). After volume adjustment by the AF power amplifier Q QQ Q1031 10311031 1031 ( TDA2003 ), the audio signal is passed to the external Speaker terminal in the accessory cable and 16 Ω internal loudspeaker. FCC ID: K66GX1255S Circuit Description Vertex Standard Co., Ltd. PLL Synthesizer PLL SynthesizerPLL Synthesizer PLL Synthesizer The 1st LO maintains stability from the PLL synthesizer by using a 21.850 MHz reference signal from crystal X XX X1001 10011001 1001. PLL synthesizer IC Q QQ Q1017 10171017 1017 ( LV2105V ) consists of a prescaler, reference counter, swallow counter, programmable counter, a serial data input port to set these counters based on the external data, a phase comparator, and a charge pump. The PLL-IC divides the 21.850 MHz reference signal by 874 using the reference counter (25 kHz comparison frequency). The VCO output is divided by the prescaler, swallow counter and programmable counter. These two signals are compared by the phase comparator and applied to the charge pump. A voltage proportional to their phase difference is delivered to the low-pass filter circuit, then fed back to the VCO as a voltage with phase error, controlling and stabilizing the oscillating frequency. This synthesizer also operates as a modulator during transmit. The VCO is comprised of Q QQ Q1020 10201020 1020 ( 2SK210GR ) and D DD D1011 10111011 1011/1012 10121012 1012, (both 1SV230 ); it oscillates at 21.4 MHz during receive, and at the fundamental frequency during transmit, with direct frequency-modulation using varactor diode D DD D1009 10091009 1009 ( 1SV214 ). The VCO output passes through buffer amplifier Q QQ Q1019 10191019 1019 ( 2SC5374 ), and is amplified by Q QQ Q1016 10161016 1016 ( 2SC5374 ) to obtain stable output. The VCO DC supply is regulated by Q QQ Q1015 10151015 1015 ( 2SC4154E ). Synthesizer output is fed to the 1st mixer by diode switch D DD D1007 10071007 1007 ( DAN235U ) during receive, and to drive amplifiers Q QQ Q1013 10131013 1013 ( 2SC5227-4 ), Q QQ Q1011 10111011 1011 ( 2SC3357 ), and Q QQ Q1001 10011001 1001 for transmit. The reference oscillator feeds the PLL synthesizer. Transmitter TransmitterTransmitter Transmitter Voice audio from the microphone is delivered via the M MM MIC ICIC IC connector to the RF Unit. After passing through amplifier Q QQ Q1028 10281028 1028 ( NJM2902M ), a pre-emphasis network, limiter (IDC: instantaneous deviation control), and LPF Q QQ Q1028 10281028 1028 ( NJM2902M ), the audio is adjusted for optimum deviation level and delivered to the next stage. Voice or DSC(Digital Selective Calling) encode signal inputs from the LPF Q QQ Q1028 10281028 1028 is 8 FM-modulated in the VCO of the synthesizer. Synthesizer output, after passing through diode switch D DD D1006 10061006 1006 ( DAN235U ), is amplified by driver Q QQ Q1013 10131013 1013 ( 2SC5227 ), Q QQ Q1011 10111011 1011 ( 2SC3357 ), and RF power amplifier Q QQ Q1001 10011001 1001 ( RA35H1516M ) to obtain full RF output. The RF energy then passes through antenna switch D DD D1003 10031003 1003 and a low-pass filter circuit and finally to the antenna connector. RF output power from the final amplifier is sampled by C1006 and C1011 and is rectified by D DD D1002 10021002 …

FCC ID: K66GX1255S Alignment Vertex Standard Co,. Ltd. 1 GX1255S GX1255S GX1255S GX1255S Alignment AlignmentAlignment Alignment The GX1255S has been carefully aligned at the factory for the specified performance across the marine band. Realignment should therefore not be necessary except in the event of a component failure. All component replacement and service should be performed only by an authorized Standard Horizon representative, or the warranty policy may be voided. The following procedures cover the sometimes critical and tedious adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts are replaced, realignment may be required. If a sudden problem occurs during normal operation, it is likely due to component failure; realignment should not be done until after the faulty component has been replaced. We recommend that servicing be performed only by authorized Standard Horizon service technicians who are experienced with the circuitry and fully equipped for repair and alignment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized Standard Horizon service technicians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty components. Those who do undertake any of the following alignments are cautioned to proceed at their own risk. Problems caused by unauthorized attempts at realignment are not covered by the warranty policy. Also, Standard Horizon, a division of VERTEX STANDARD, must reserve the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function and operation of the transceiver are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and the need for realignment determined to be absolutely necessary. The following test equipment (and thorough familiarity with its correct use) is necessary for complete realignment. Correction of problems caused by misalignment resulting from use of improper test equipment is not covered under the warranty policy. While most steps do not require all of the equipment listed, the interactions of some adjustments may require that more complex adjustments be performed afterwards. Do not attempt to perform only a single step unless it is clearly isolated electrically from all other steps. Have all test equipment ready before beginning, and follow all of the steps in a section in the order presented.

GX1260S Marine Transceiver Alignment Preparation & Precautions Alignment Preparation & PrecautionsAlignment Preparation & Precautions Alignment Preparation & Precautions A dummy load and inline wattmeter must be connected to the main antenna jack in all procedures that call for transmission. Correct alignment is not possible with an antenna. After completing one step, read the following step to determine whether the same test equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, if connected) before proceeding. Correct alignment requires that the ambient temperature be the same as that of the transceiver and test equipment, and that this temperature be held constant between 20°C and 30°C (68°F and 86°F). When the transceiver is brought into the shop from hot or cold air it should be allowed some time for thermal equalization with the environment before alignment. If possible, alignments should be made with oscillator shields and circuit boards firmly affixed in place. Also, the test equipment must be thoroughly warmed up before beginning. Note: Signal levels in dB referred to in this procedure are based on 0 dBμ = 0.5 μV (closed circuit). Overview of Test Mode Overview of Test ModeOverview of Test Mode Overview of Test Mode The test mode has been build in the microprocessor in order to adjust and confirm the performance of transceiver.

Name of test:Environmental Assessment Specification:FCC: 47 CFR 1.1310 Measurement Guide:ANSI/IEEE C95.1 1992 Test Equipment:Maximum Permissible Exposure (MPE) measurement system, consisting of: Narda 8717-1174R, Radiation meter Narda 8761D, E-field probe (300 kHz – 3 GHz) (Calibrated Nov-98) Measurement Procedure: 1. The following measurements were performed with a Narda probe using ANSI/IEEE C95.1 as a guide. 2. Prior to making any measurements, the measurements system was calibrated in accordance with the manufacturer’s procedures. 3. The EUT’s radiating element (antenna) was placed ona1mtall table for ease of testing. For equipment normally operated on a metal surface, a ground plane was used. 4. The remaining equipment necessary to operate the EUT was maintained at a distance from the measurement arrangement suitable to minimize interference with the measurements. 5. The minimum safe distance was calculated from the formula Power Density = EIRP / 4πR 2 (Peak Watts/m 2 ). The calculation is shown with the measurement data. 6. With the EUT operating at maximum power, a search was initiated for worst case emissions with t…
