Keysight 849x and 1158x Operating and Service Manual

29

Service Instructions

Repair

The 8490D/G, 8491A/B the 8493A/B/C attenuators are not recommended for repair since the 

cards must be mounted in cartridges to test and testing costs more than a replacement attenuator.

Maintenance

The connectors, particularly the connector faces, must be kept clean. This is especially true of the 

8493A/B/C.
For instruction on connecting and care of your connectors, refer to the Microwave Connector Care 

Quick Reference Card (08510-90360).
