Keysight Technologies N5290/1A PNA and PNA-X Series 2-Port and 4-Port Microwave Network Analyzer Systems Service Guide Safety and Regulatory Information Information in This Chapter This chapter provides safety information that will help protect you and your system’s equipment. It also contains information that is required by various government regulatory agencies.
Page 12: Safety Symbols
Safety and Regulatory Information Safety Symbols Safety Symbols The following safety symbols are used throughout this manual. Familiarize yourself with each of the symbols and its meaning before operating this instrument. Caution denotes a hazard. It calls attention to a procedure that, if not correctly performed or adhered to, could result in damage to or destruction of the instrument.
Page 13: General Safety Considerations
Safety and Regulatory Information General Safety Considerations General Safety Considerations Safety Earth Ground This is a Safety Class I product (provided with a protective earthing ground incorporated in the power cord). The mains plug shall only be inserted in a socket outlet provided with a protective earth contact.
Page 14 Safety and Regulatory Information General Safety Considerations Supply voltages which oscillate between the two normal input ranges of the autoranging line voltage input will damage the power supply. In rare cases, this damage has become a user safety concern. If unstable power levels are expected, the analyzer input power must be buffered by a line conditioner.
Page 15: Servicing
Safety and Regulatory Information General Safety Considerations Servicing These servicing instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing unless you are qualified to do so. Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended.
Page 16 Safety and Regulatory Information General Safety Considerations There are no replaceable fuses in the mains input or within the power supply assembly. Keysight personnel: after calibration is completed, attach four “calibration void if seal broken” stickers to the PNA as shown in Figure 1-1.
Page 17: Electrostatic Discharge Protection
Safety and Regulatory Information Electrostatic Discharge Protection Electrostatic Discharge Protection This is important. If not properly protected against, electrostatic discharge can seriously damage your analyzer, resulting in costly repair. Protection against electrostatic discharge (ESD) is essential while removing assemblies from or connecting cables to the network analyzer. Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged.
