–
Data questionable;Lower window log error
231
This indicates that a difference measurement in the lower window has given a negative result when the
units of measurement were logarithmic.
–
Data questionable;Upper window log error
231
This indicates that a difference measurement in the upper window has given a negative result when the
units of measurement were logarithmic.
–
Data questionable;ZERO ERROR
231
Power meter zeroing failed. The most likely cause is attempting to zero when some power signal is being
applied to the power sensor.
–
Data questionable;ZERO ERROR ChA
231
Power meter zeroing failed on Channel A. The most likely cause is attempting to zero when some power
signal is being applied to the power sensor.
– Data questionable;ZERO ERROR ChB
231
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.
– Hardware missing
241
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.
– System error;Dty Cyc may impair accuracy with ECP sensor
310
This indicates that the sensor connected is for use with CW signals only.
–
System error;Ch A Dty Cyc may impair accuracy with ECP sensor
310
This indicates that the sensor connected to Channel A is for use with CW signals only.
–
System error;Ch B Dty Cyc may impair accuracy with ECP sensor
310
This indicates that the sensor connected to Channel B is for use with CW signals only.
–
System error;Sensor EEPROM Read Failed - critical data not found or unreadable
310
This indicates a failure with your E-Series Power Sensor. Refer to your power sensor manual for details on
returning it for repair.
–
System error;Sensor EEPROM Read Completed OK but optional data block(s) not found or unreadable
310
This indicates a failure with your E-Series Power Sensor. Refer to your power sensor manual for details on
returning it for repair.
–
System error;Sensor EEPROM Read Failed - unknown EEPROM table format
310
This indicates a failure with your E-Series Power Sensor. Refer to your power sensor manual for details on
returning it for repair.
