General Information
This chapter contains information about general maintenance, performance tests,
troubleshooting and repair of the P-Series Wideband Power Sensors.
Cleaning
Use a clean, damp cloth to clean the body of the P-Series Wideband Power Sensor.
Connector Cleaning
The RF connector beads deteriorate when contacted by hydrocarbon compounds
such as acetone, trichloroethylene, carbon tetrachloride, and benzene.
Clean the connector only at a static free workstation. Electrostatic discharge to
the center 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 a round wooden toothpick wrapped in a lint free cotton cloth
dipped in isopropyl alcohol.
Performance Test
The Performance and Calibration Tests require the sensor to be returned to the
factory.
To arrange this contact the service centre. See
Offices"
Repair of Defective Sensor
There are no serviceable parts inside the P-Series Wideband Power Sensors. If the
sensor is defective, it needs to be returned to a Keysight service center.
