-230 Data corrupt or stale;Please zero and calibrate Channel A
When CAL[1|2]:RCAL is set to ON and the sensor currently connected
to channel A has not been zeroed and calibrated, then any command
which would normally return a measurement result (for example
FETC?, READ?, or MEAS?) will generate this error message.

-230 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.
