Grounding of equipments

[adnansiddiqui]

I work in RF lab and use the spectrum Analyzer, signal generator, Network analyzer etc for our testing purpose. But the equipments are not grounded therefore the charges are emmitted from their ports.

Please mention me steps to properly ground the equipments.

Instruments are normally grounded to Earth by the third (ground) wire in the AC mains power cord. Maybe your lab's AC wall outlets are wired incorrectly. Maybe your instruments' AC cords are of incorrect type for your country (such as plugging a Continental Europe AC cord into a Denmark wall outlet).

Maybe somebody deliberately defeated the safety ground system in your lab. Ask them why! Maybe they had a special reason for doing it.
