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).
