4. Troubleshooting
NOTE When Crosstalk, System dynamic range or Uncorrected system performance test fails,
check first whether the connections of the RF semi-rigid cables between the suspicious
assembly and others are tight or loose. Also check for possible disconnection (impairment)
of the cables and connectors.
