To inspect the socket, use Magnifier to visually inspect socket and clean according to original manufacturers instructions.

To inspect the DIB, visually Device Interface Board for clean DC pads and RF launches and look for damaged components. Reference the design documentation for expected performance. (Optional, develop Diagnostics for this DIB.)

To inspect Test Head TIM Blocks, follow the procedure to remove the Fixture and visually inspect the RF launches with a Magnifier to look for bend pins. Use Connector Cleaner without lubrication and compressed air to clear any debris.

To inspect Fixture Inserts/Launches, remove the Device Interface Board board visually Device Interface Board for clean DC pads and RF launches.

To calibrate the Fixture; normally DO NOT CALIBRATE FIXTURE. This step should only be done if the Fixture changes unless there is a required reason to calibrate at every setup; possible with high power devices with poor match. Follow the Fixture Calibration procedure.

To inspect docking hardware, undock the Fixture and look for wear.

To Diagnose/Verify the tester, latch the Diag/Cal Fixture and follow the Diagnose procedure.

To Calibrate TIMs, latch the Diag/Cal Fixture and follow the Calibration procedure that includes running Diagnostics first.

To Calibrate RF System, latch the Diag/Cal Fixture and follow the Calibration procedure that includes running Diagnostics first.
