attribute:
smua.source.offfunc = smua.OUTPUT_DCVOLTS
To set 0 A output with voltage limit set by the
smua.source.offlimitv
attribute:
smua.source.offfunc = smua.OUTPUT_DCAMPS
Output-off limits (compliance)
You can set output-off limits (compliance) for the current and voltage output-off functions using the
CONFIG menu on the Model 2657A front panel, or by setting the
smua.source.offlimit
Y
attribute from a remote interface. The output-off limits only apply when the output-off mode is normal.
Setting the output-off limit for CURRENT (

) specifies the current limit for
the voltage source; setting the output-off limit for VOLTAGE (
smua.source.offlimitv
) specifies
the voltage limit for the current source.
