4.2.2 Electro-static Discharge (ESD) Protection
ESD is an issue often ignored by users. Damage from ESD on the
instrument is unlikely to occur immediately but will significantly
reduce the reliability of it. Therefore, ESD precautions should be
implemented in the work environment, and applied daily.
Generally, there are two steps to manage ESD protection:
1) Conductive table mat to connect hands via wrist bands
2) Conductive ground mat to connect feet via ankle straps
Implement both protection methods will provide a good level of
anti-static protection. If used alone, the protection will not be as
reliable. To ensure user’s safety, anti-static components should
offer at least
1MΩ isolat
ion resistance.
Make good use of anti-static technology to protect components
from damage:
1) Quickly ground the internal and external conductor of the coaxial
cable before it is connected to the spectrum analyzer.
2) Staff must wear anti-static gloves before touching the connector
cord or doing any assemble work.
3) Assure all the instruments are grounded properly to avoid static
storage.

Note: Keep the air vents always clear of obstructions for proper
!
WARNING
The above ESD protections measures cannot be used
when working with over 500V!
