Operation and Service Guide
Service
If error message 241 or 310 is indicated on the power meter, suspect a failed
power sensor. If no error message is displayed, but a problem occurs when
making a measurement, try replacing the cable from the power meter to the
power sensor. If the problem still exists, try using a different power sensor to
determine if the problem is in the power meter or in the power sensor.
CAUTION:Electrostatic discharge will render the power sensor inoperative. Do not, under any
circumstances, open the power sensor unless you and the power sensor are in a static
free environment.
Repair of Defective Sensor
There are no serviceable parts inside the E44XX-Series sensors. If the sensor
is defective, replace the entire ?module? with the appropriate ?Restored Sen-
sor Module.? See Table 6.
Cleaning
Cleaning Solutions
Keeping in mind its flammable nature; a solution of pure isopropyl or ethyl
alcohol can be used to clean the connector.
Connector Cleaning
CAUTION:The RF connector beads deteriorate when contacted by hydrocarbon compounds
such as acetone, trichloroethylene, carbon tetrachloride, and benzene.
CAUTION:Clean the connector only at a static free workstation. Electrostatic discharge to the
center pin of the connector will render the power sensor inoperative.
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 cot-
ton cloth dipped in isopropyl alcohol. Refer to Agilent Application Note
326, Principals of Microwave Connector Care (5954-1566) or Microwave
Connector Care (08510-90064) for proper cleaning methods.
