Introduction 1
Agilent E4412A and E4413A Power Sensors Operating and Service Guide 21
If error message 241 or 310 is indicated on the power meter, suspect
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.
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
sensor 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
C A U T I O N
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.
C A U T I O N
The RF connector beads deteriorate when contacted by hydrocarbon compounds such
as acetone, trichloroethylene, carbon tetrachloride, and benzene.
C A U T I O N
Clean the connector only at a static free workstation. Electrostatic discharge to the
center pin of the connector will render the power sensor inoperative.
