231
Data questionable;ZERO ERROR ChB
Power meter zeroing failed on Channel B. The most likely cause is attempting to zero
when some power signal is being applied to the power sensor.
–
241
Hardware missing
The power meter is unable to execute the command because either no power sensor is
connected or it expects an E-series power sensor and one is not connected.
–
310
System error;Dty Cyc may impair accuracy with ECP sensor
This indicates that the sensor connected is for use with CW signals only.
–
310
System error;Ch A Dty Cyc may impair accuracy with ECP sensor
This indicates that the sensor connected to Channel A is for use with CW signals only.
–
310
System error;Ch B Dty Cyc may impair accuracy with ECP sensor
This indicates that the sensor connected to Channel B is for use with CW signals only.
–
310
System error;Sensor EEPROM Read Failed - critical data not found or unreadable
This indicates a failure with your E-Series or N8480 Series power sensor. Refer to your
power sensor manual for details on returning it for repair.
–
310
System error;Sensor EEPROM Read Completed OK but optional data block(s) not found
or unreadable
This indicates a failure with your E-Series or N8480 Series power sensor. Refer to your
power sensor manual for details on returning it for repair.
–
310
System error;Sensor EEPROM Read Failed - unknown EEPROM table format
This indicates a failure with your E-Series or N8480 Series power sensor. Refer to your
power sensor manual for details on returning it for repair.
–
310
System error;Sensor EEPROM < > data not found or unreadable
Where < > refers to the sensor data block covered, for example, Linearity, Temp - Comp
(temperature compensation).
This indicates a failure with your E-Series or N8480 Series power sensor. Refer to your
power sensor manual for details on returning it for repair.
