Prevent Damage to Network Analyzers
应用文章
Ensure proper grounding
– Always use the three-prong AC power cord supplied with the analyzer
– Proper grounding of the instrument will prevent a build-up of electrostatic charge which may be harmful to the instrument and the operator
– Do not damage the earth-grounding protection by using an extension cable, power cable, or autotransformer without a protective ground conductor
– Check AC power quality and polarity; typical AC voltage required is 110 V, 120 V, 220 V ± 10% or 240 V +5%/–10%. Typical expected grounding wire resistance is < 1 Ω, the voltage between neutral and ground line is < 1 V. Install uninterruptible power supply [UPS] if necessary
