WARNING
Make sure the supply power is stable before turning on the
analyzer to protect it from damage. Refer to "First Time to
Power on" section 3.
4.2.4 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 mats 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 isolation 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 with 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.
4.3 First Time to Power on
Connect the three-pin AC power cord into the instrument. Insert the
plug into a power socket provided with a protective ground.

WARNING
The above ESD protections measures cannot be used
when working with over 500V!
