General Information General Information General Information In this chapter, you will find general information on caring for your optical devices. Safety first! Before servicing the mainframe, familiarize yourself with the safety markings on the instrument and the safety instructions in this manual. This instrument has been manufactured and tested according to international safety standards.
General Information General Reference General Reference Whenever you contact Agilent Technologies about your mainframe, have the complete serial number and option designation available. This will ensure you obtain accurate service information. • Refer to Table 1-1 for a list of internal labels. Clean the cabinet using a damp cloth only. Protect against ESD damage Electrostatic discharge (ESD) can damage or destroy electronic components.
General Information Cleaning Optical Connectors Cleaning Optical Connectors Accurate and repeatable measurements require clean connections. Use the following guidelines to achieve the best possible performance when making measurements on a fiber-optic system: • Keep connectors covered when not in use. • Use dry connections whenever possible. • Use the cleaning methods described in this section. • Use care in handling all fiber-optic connectors.
General Information Cleaning Optical Connectors Table 1-2. Cleaning Accessories Item Agilent Part Number Pure isopropyl alcohol — Cotton swabs 8520-0023 Small foam swabs 9300-1223 Compressed dust remover (non-residue) 8500-5262 Table 1-3.
General Information Cleaning Optical Connectors To clean a non-lensed connector CAUTION Do not use any type of foam swab to clean optical fiber ends. Foam swabs can leave filmy deposits on fiber ends that can degrade performance. 1 Apply isopropyl alcohol to a clean, lint-free cotton swab or lens paper. Cotton swabs can be used as long as no cotton fibers remain on the fiber end after cleaning. 2 Before cleaning the fiber end, clean the ferrules and other parts of the connector.
General Information Cleaning Optical Connectors To clean an adapter 1 Apply isopropyl alcohol to a clean foam swab. Cotton swabs can be used as long as no cotton fibers remain after cleaning. The foam swabs listed in this section’s introduction are small enough to fit into adapters. Although foam swabs can leave filmy deposits, these deposits are very thin, and the risk of other contamination buildup on the inside of adapters greatly outweighs the risk of contamination by foam swabs.
General Information Cleaning Optical Connectors Cleaning Electrical Connections The following list includes the basic principles of microwave connector care.
General Information Electrostatic Discharge Information Electrostatic Discharge Information Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic assemblies should be performed at a static-safe work station. The following figure shows an example of a static-safe work station using two types of ESD protection: • Conductive table-mat and wrist-strap combination. • Conductive floor-mat and heel-strap combination.
General Information Electrostatic Discharge Information WA R N I N G These techniques for a static-safe work station should not be used when working on circuitry with a voltage potential greater than 500 volts. Table 1-4. Static-Safe Accessories HP Part Number 1-10 Description 9300-0797 3M static control mat 0.6 m × 1.2 m (2 ft × 4 ft) and 4.6 cm (15 ft) ground wire. (The wrist-strap and wrist-strap cord are not included. They must be ordered separately.) 9300-0980 Wrist-strap cord 1.5 m (5 ft).
General Information Returning the Instrument for Service Returning the Instrument for Service The instructions in this section show you how to properly return the instrument for repair or calibration. Always call the Agilent Instrument Support Center first to initiate service before returning your instrument to a service office. This ensures that the repair (or calibration) can be properly tracked and that your instrument will be returned to you as quickly as possible.
General Information Returning the Instrument for Service CAUTION Cover electrical connectors to protect sensitive components from electrostatic damage. Cover optical connectors to protect them from damage due to physical contact or dust. CAUTION Instrument damage can result from using packaging materials other than the original materials. Never use styrene pellets as packaging material. They do not adequately cushion the instrument or prevent it from shifting in the carton.
