Data corrupt or stale
This occurs when a
FETC?
meter state has changed such that the current measurement is invalidated (for example, a
change of frequency setting or triggering conditions).
Data corrupt or stale;Please zero and calibrate Channel A

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.
Data questionable;Input Overload
The power input to Channel A exceeds the power sensor's maximum range.
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.
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.
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.
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.
