–230 Data corrupt or stale
This occurs when a FETC? is attempted and either a reset has been received or the power
meter state has changed such that the current measurement is invalidated (for example, a
change of frequency setting or triggering conditions).
–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 zero Channel A
When CAL[1|2]:RCAL is set to ON and the sensor currently connected to channel A
has not been zeroed, 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 A
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 or N8480 Series power sensor, and one is not
connected.
