Data corrupt or stale;Please calibrate Channel A
When CAL[1|2]:RCAL is set to ON and the sensor currently connected to
channel B has not been calibrated, then any command which would normally
return a measurement result (for example FETC?, READ?, or MEAS?) will
generate this error message
-231
Data questionable;CAL ERROR
Power meter calibration failed. The most likely cause is attempting to calibrate
without applying a 1 mW power to the power sensor.
-231
Data questionable;Input Overload
The power input to Channel A exceeds the power sensor's maximum range.
-231
Data questionable;Lower window log error
This indicates that a difference measurement in the lower window has given a
negative result when the units of measurement were logarithmic.
-231
Data questionable;Upper window log error
This indicates that a difference measurement in the upper window has given a
negative result when the units of measurement were logarithmic.
-231
Data questionable;ZERO ERROR
Power meter zeroing failed. 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 Agilent 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;Sensor EEPROM Read Failed - critical data not found or
unreadable
This indicates a failure with your Agilent E-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 Agilent E-series power sensor. Refer to your
power sensor manual for details on returning it for repair.
