General Information
This chapter contains information about general maintenance, performance
tests, troubleshooting and the repair of U2000 Series USB power sensors.
Cleaning
Use a clean, damp cloth to clean the body of the U2000 Series USB power
sensors.
Connector Cleaning
The RF connector beads deteriorate when contacted with hydrocarbon compounds such as
C A U T I O N
acetone, trichloroethylene, carbon tetrachloride, and benzene.
Clean the connector only at a static free workstation. Electrostatic discharge to the center
C A U T I O N
pin of the connector will render the power sensor inoperative.
Keeping in mind its flammable nature, a solution of pure isopropyl or
ethyl alcohol can be used to clean the connector.
Clean the connector face using a cotton swab dipped in isopropyl alcohol.
If the swab is too big use, use a round wooden toothpick wrapped in a
lint- free cotton cloth dipped in isopropyl alcohol.
Refer to Keysight Application Note 326, Principles of Microwave Connector
Care (5954- 1566) for proper cleaning methods.
