Description
This message appears when overload occurs. The returned value is
"9.9E37" when using the SCPI command. Conditions in which
overload occurs differ depending on the impedance range
settings. For details, refer to
This appears when no measurement was performed, or the
measurement result is beyond the display range.
This message appears when the deviation mode of the deviation
measurement function is % and the measurement result cannot be
calculated.
Cond itions
• E4980A/AL's internal detector detects overload
• When the DUT's distortion is large
• When the DUT's response is slow
Conditions differ depending on the impedance range. Refer to
