Installation Note E8362-90016
Installation Procedure for the Upgrade Kit
The network analyzer must be in proper working condition prior to installing this option. Any
necessary repairs must be made before proceeding with this installation.
WARNING
This installation requires the removal of the analyzer’s protective outer
covers. The analyzer must be powered down and disconnected from the
mains supply before performing this procedure.
Electrostatic Discharge Protection
Protection against electrostatic discharge (ESD) is essential while removing or connecting
cables or assemblies within the network analyzer.
Static electricity can build up on your body and can easily damage sensitive internal circuit
elements when discharged. Static discharges too small to be felt can cause permanent
damage. To prevent damage to the instrument:
•
always
wear a grounded wrist strap having a 1 M
Ω
resistor in series with it when handling
components and assemblies.
•
always
use a grounded, conductive table mat while working on the instrument.
•
always
wear a heel strap when working in an area with a conductive floor. If you are
uncertain about the conductivity of your floor, wear a heel strap.
•
always
ground yourself before you clean, inspect, or make a connection to a static-sensitive
device or test port. You can, for example, grasp the grounded outer shell of the test port or
cable connector briefly.
