Attempts by non-qualified persons to service this equipment may result in permanentdamage not covered by the warranty, and may be illegal insome countries.Two PCB layout diagrams are provided for each doublesided circuit board in the Transceiver. Each side of is referred to by the type of the majority of components installed on that side (“leaded” or “chip-only”). In mostcases one side has only chip components, and the otherhas either a mixture of both chip and leaded components(trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.FT-450While we believe the technical information in this manual to be correct, VERTEX STANDARD assumes no liability for damage that may occur as a result of typographical or other errors that may be present. Your cooperationin pointing out any inconsistencies in the technical information would be appreciated.FT-450DContentsSpecificationsExploded View & Miscellaneous PartsBlock DiagramConnection DiagramAlignmentBoard Unit (Schematics, Layouts & Parts)RF-IF UnitPANEL UnitCNTL UnitPA UnitTUNER Unit (FT-450 Option:ATU-450 )

AlignmentIntroduction and PrecautionsRequired Test EquipmentThe following procedures cover adjustments that arenot normally required once the transceiver has leftthe factory. However, if a problem occurs duringnormal operation due to component failure; realignment may be required after the faulty componentshave been replaced. We recommend that authorized Vertex StandardTechnicians, who are experienced with the circuitryand fully equipped to repair and align our products,perform repairs. If a fault is suspected, contact theselling dealer for instructions regarding repair. Authorized Vertex Standard Technicians have the latest information to align all circuits and make complete performance checks to ensure compliance withfactory specifications after repairs.Those who undertake the following alignments arecautioned to proceed at their own risk. Problemscaused by unauthorized attempts at realignment arenot covered by the warranty policy.Vertex Standard must reserve the right to changecircuits and alignment procedures in the interest ofimproved performance, without notifying owners.Under no circumstances should any alignment beattempted unless the normal functions and operation of the transceiver are clearly understood, thecause of the malfunction has been clearly identifiedand all faulty components replaced. The need forrealignment should be determined to be necessary.The following test equipment (and a thorough familiarity with its correct use) is necessary for correctalignment. Most steps do not require all of the equipment listed. The interactions of some adjustmentsmay require that several adjustments be performedin a sequence. Do not attempt to perform only a single step unless it is clearly isolated electrically fromall other steps. Have all test equipment ready beforebeginning, and follow all of the steps in a section inthe order they are presented.FT-450 Series Technical SupplementRF Signal GeneratorAF Signal GeneratorSpectrum Analyzer good to at least 1 GHz.Frequency CounterSINAD MeterRF MillivoltmeterDigital DC Voltmeter (high-Z, 1 M-Ohm/V)DC VoltmeterDC Ammeter (20 A)Ohmmeter50-Ohm Dummy Load (100 watts)16.6-Ohm Dummy Load (100 watts)In-Line Wattmeter (100 watts, 50-Ohm)Linear DetectorRF Coupler4-Ohm AF Dummy Load (3 watts)Alignment Preparation & PrecautionsA 50-ohm RF Dummy load and in-line wattmetermust be connected to the "ANT" jack in all procedures that call for transmission, except where specified otherwise. Correct alignment is not possible withan antenna.After completing one step, read the following stepto determine whether the same test equipment willbe required. If not, remove the unneeded test equipment before proceeding (except the dummy load andwattmeter).Correct alignment requires that the ambient temperature be maintained constant between 68 F 86 F(20 C 30 C). When the transceiver is brought intothe shop from a hot or cold environment, it shouldbe allowed time to come to room temperature before alignment. Also, the test equipment must bethoroughly warmed up before beginning.Whenever possible, alignments should be made withoscillator shields and circuit boards firmly affixed inplace.Note: Signal levels in dB referred to in this procedure are based on 0 dBμ 0.5 μV (closed circuit).ALIGNMENT-1
