NOTE If the message "CAUTION: DCBIAS OVERLOAD" (error number: 137) still appears
even when the dc bias range is set to 100 mA, the connected DUT requires a dc bias with a
current that exceeds the maximum dc bias current (100 mA) provided by the Agilent
4294A. In this case, decrease the dc bias voltage level to avoid the error.
