Service Guide Assembly-Level Repair The 8590 Series Analyzers Assembly-Level Repair Service Guide provides the information needed to adjust and repair the 8590 E-Series and L-Series spectrum analyzers, the 8591C cable TV analyzer and 8594Q QAM analyzer to the assembly level. The 8590 Series Analyzers Component-Level Repair Service Guide provides component-level information for the repair of individual analyzer assemblies. The binder contains Component-Level Information Packets (CLIPs) for selected assemblies. Each CLIP contains component-level schematics, a component parts list, and illustrations for component location by reference designator. Each CLIP has its own part number which is changed whenever the part number for its related analyzer assembly is changed. A list of all CLIP part numbers for the 8590 E-Series and L-Series spectrum analyzers, 8591C cable TV analyzers, and 8594Q QAM analyzers is provided in Chapter 12 of this service guide. The guide is divided into the following chapters. • Chapter 1, “Introduction,” contains information on the analyzer identification, firmware revisions and upgrades, and safety and reliability considerations. • Chapter 2, “Making Adjustments,” contains the adjustment procedures needed to adjust the analyzer to meet its specifications. • Chapter 2a, “Making Adjustments: 3335A Source Not Available,” contains the adjustment procedures needed to adjust the analyzer to meet its specifications when a 3335A source is not available. • Chapter 3, “Backing Up and Reloading Correction Constants,” contains information for safe-guarding the correction data stored in the analyzer and restoring the analyzer memory. • Chapter 4, “Troubleshooting the Analyzer,” contains information for starting to troubleshoot a analyzer failure. • Chapter 5, “Troubleshooting the IF Section,” contains specific troubleshooting information for selected assemblies in the IF section and the A15 Motherland assembly. • Chapter 6, “Troubleshooting the RF Section,” contains troubleshooting information for the RF and LO sections of the 8590 E-Series and L-Series spectrum analyzer and 8591C cable TV analyzer. The information is separated by the following tabs. • Chapter 6a, “8590L, 8591C and 8591E,” contains specific troubleshooting information for selected assemblies within the RF and LO sections of the 8590L, 8591E spectrum analyzers, and 8591C cable TV analyzers. • Chapter 6b, “8592L/94L, 8594Q, and 8593E/94E/95E/96E,” contains specific troubleshooting information for selected assemblies within the RF and LO sections of the 8592L, 8594L, 8593E, 8594E, 8595E, 8596E spectrum analyzers, and the 8594Q QAM analyzer. • Chapter 7, “Replacing Major Assemblies,” contains instructions for the removal and replacement of most major assemblies. • Chapter 8, “Contacting Agilent Technologies,” contains information on how to contact Agilent Technologies and return the analyzer for repair. • Chapter 9, “Assembly Descriptions and Block Diagrams,” contains information and block diagrams describing analyzer operation and individual assemblies. •Chapter 10, “Analyzer Options and Block Diagrams,” contains information on the available analyzer options. •Chapter 11, “Major Assembly and Cable Locations,” contains figures identifying all major assemblies and cables. •Chapter 12, “Replaceable Parts,” contains information needed to order assemblies and component-level information for the analyzer. •Chapter 13, “Softkey Descriptions,” contains a description of the calibration, service, and diagnostic softkeys. •Chapter 14, “Analyzer Messages,” contains a description of the analyzer messages that are displayed when there is a problem with the analyzer. •Chapter 15, “Service Equipment and Tools,” contains information about equipment and tools used to service the analyzer.
