MEASUREMENT IN QUESTION TROUBLESHOOTING

NOTE

The procedures for performing pin depth measurements for the connectors used on ANRITSU products are con- tained in Appendix C, Connector Maintenance Check Pro- cedures.

3.Check the system performance as follows:

￿Perform the Signal Path Tests that are part of the Operational Tests. Refer to Chapter 3, Operational Tests.

￿Check Match, Directivity, and Dynamic Range as described in Chapter 4, Performance Verification.

￿Complete the remaining checks described in Chapter 4 (Per- formance Verification).
