Protecting Against Electrostatic Discharge
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).
