Troubleshooting
Troubleshooting information is intended to first isolate the power sensor,
cable, or power meter as the defective component. When the power sensor
is isolated, an appropriate sensor module must be used for repair. See
Table 3- 2
If error message 241 or 310 is displayed on the power meter, suspect a
power sensor failure. Error 241 will occur if the power sensor is missing.
A supported cable must be used to connect the N8480 Series power
sensors to a power meter.
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.
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
There is no serviceable parts inside the N8480 Series power sensors. If the
power sensor is defective, send it back to the nearest Keysight Service
Center for repair. The entire "module" of the defective power sensor will
be replaced with an appropriate replacement module listed in
and
N8480 Series Power Sensors Operating and Service Guide
