Protecting Against Electrostatic Discharge

Electrostatic discharge (ESD) can damage or destroy electronic components (the possibility of unseen damage caused by ESD is present whenever components are transported, stored, or used).

Test Equipment and ESD

To help reduce ESD damage that can occur while using test equipment:

• Before connecting any coaxial cable to an analyzer connector for the

first time each day, momentarily short the center and outer conductors of the cable together.

• Personnel should be grounded with a 1 MΩ resistor-isolated

wrist-strap before touching the center pin of any connector and before removing any assembly from the analyzer.

• Be sure that all instruments are properly earth-grounded to prevent

build-up of static charge.

WAR NING Do not use these first three techniques when working on

circuitry with a voltage potential greater than 500 volts.

• Perform work on all components or assemblies at a static-safe

workstation.

• Keep static-generating materials at least one meter away from all

components.

• Store or transport components in static-shielding containers.

• Always handle printed circuit board assemblies by the edges. This

reduces the possibility of ESD damage to components and prevent contamination of exposed plating.

Installation and Setup

For information on ordering static-safe accessories, see “Accessories” on page 71.

Additional Information about ESD

For more information about ESD and how to prevent ESD damage, contact the Electrostatic Discharge Association (http://www.esda.org). The ESD standards developed by this agency are sanctioned by the American National Standards Institute (ANSI).

Chapter 1 21

Installation and Setup

Safety Information

WAR NING This is a Safety Class 1 Product (provided with a protective

earthing ground incorporated in the power cord). The mains plug shall be inserted only in a socket outlet provided with a protective earth contact. Any interruption of the protective conductor inside or outside of the product is likely to make the product dangerous. Intentional interruption is prohibited.

If this product is not used as specified, the protection provided by the equipment could be impaired. This product must be used in a normal condition (in which all means for protection are intact) only.
