Lists not same length
This occurs when SENSe:CORRection:CSET[1]|CSET2:STATe is set to ON and the frequency and
calibration/offset lists do not correspond in length.

Data corrupt or stale;Please calibrate Channel B
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;CAL ERROR ChA
Power meter calibration failed on Channel A. The most likely cause is attempting to calibrate without
applying a 1 mW power to the power sensor.
–231
Data questionable;CAL ERROR ChB
Power meter calibration failed on Channel B. 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;Input Overload ChA
The power input to Channel A exceeds the power sensor's maximum range.
–231
Data questionable;Input Overload ChB
The power input to Channel B 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.
–231
Data questionable;ZERO ERROR ChA
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.
