Troubleshooting
Check the following:
1.
Verify that the lead screw is tight.
2.
Verify that the shroud fits snugly against the faceplate (the cutouts are closed).
3.
Verify that the cables are properly seated and secure in the UCH.
If downstream RF power measurements are made, use these ESD precautions to prevent damage to the
product:
1.
Check for a proper ground on the equipment and chassis before connecting any cables.
2.
Ensure that there is a common ground between all the test equipment that you are using and the unit
under test.
3.
Keep test cables as short as possible to limit static buildup.
4.
Before attaching any test cables to the unit under test, momentarily ground the center pin of the test
cable to remove any ESD potential that may be present.
