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 The 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.
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 MΩresistor 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.
Figure 1-1 shows a typical ESD protection setup using a grounded mat and wrist strap. Refer
to Table 2, “Required Equipment and Tools” on page 8 for part numbers.
