Exposure to ESD can damage this product. 

If downstream RF power measurements are made to this line card, all the ESD precautions listed below 
must be followed to prevent damage to the product:

Check for a proper ground on the equipment and chassis before connecting any cables.

Ensure there is a common ground between all the test equipment and the unit under test.

Keep test cables as short as possible to limit static buildup.

Before attaching any test cables to the unit under test, momentarily ground the center pin of the test 
cable to remove any static buildup that may be present.
