–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.
–232 Invalid format
–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 or N8480 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 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 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 power sensor. Refer to your
power sensor manual for details on returning it for repair.
–310 System error;Sensors connected to both front and rear inputs.
You cannot connect two power sensors to the one channel input. In this instance the power meter detects
power sensors connected to both it's front and rear channel inputs.
–321 Out of memory
The power meter required more memory than was available to run an internal operation.
