Electrostatic Discharge Protection
Electrostatic discharge (ESD) damages or destroys electronic components (the possibility of unseen damage caused by
ESD is present whenever transported, stored, or while the instrument is in use).
This product contains components that are easily damaged by electrostatic discharge. To help reduce the possibility of
ESD damage that can occur while using test equipment, follow these guidelines:
1
Before connecting any coaxial cable to the spectrum analyzer connector for the first time each day, momentarily short the center and outer conductors of the cable together to eliminate any potential electrostatic charges that may exist.
2
Personnel should be grounded with an approved type, 1 M
W resistor- isolated ESD wrist- strap before touching the center pin of any connector, and before removing any assembly from the spectrum analyzer.
3
Be sure that all instruments are properly earth grounded to prevent build- up of static charges.
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).
