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
