Section 12: Instrument Control Library
Remarks • Reading this attribute gives the output-off mode of the source. Setting this attribute
configures the SMU output-off mode.
• The default offmode is smuX.OUTPUT_NORMAL. In this mode, the SMU will source 0
volts. For the 2601/2602, the compliance to 10% of the current source range or 100uA,
whichever is smaller. If the source function is voltage, the 10% compliance will inherently
be a reduction in compliance current. If the source function is current, the 10%
compliance value may be more or less than the current that was being sourced. For the
2611/2612/2635/2636, the compliance to the value specified by
smuX.source.offlimiti (default 1mA).
• When
when the output is turned off.
• When the offmode is set to smuX.OUTPUT_ZERO, the SMU will source 0 volts just as
OUTPUT_NORMAL mode does. If the source function is voltage, the current limit will not be
changed. If the source function was current, the current limit will be set to the current
source level or 10% of the current source range, whichever is greater.
