SMU 2 configuration (sources one-half of the total pulse current):
Source function:
smua.source.func = smua.OUTPUT_DCAMPS
Source range:
smua.source.rangei = 10
Idle (bias) source level (source level at base of pulse):
smua.source.leveli = 0
Idle (bias) source limit (source limit at base of pulse). Set the SMU 2 idle source limit ten percent
lower than the SMU 1 idle source limit:
smua.source.limitv = 5.4
Pulse source level (source level at top of pulse):
smua.trigger.source.listi({10})
Pulse source limit. SMU 2 controls the source limit for the combined SMUs. Set the voltage source
limit of SMU 2 ten percent lower than the source limit of SMU 1:
smua.trigger.source.limitv = 18
Output-off mode:
smua.source.offmode = smua.OUTPUT_NORMAL
Output-off function:
smua.source.offfunc = smua.OUTPUT_DCVOLTS
Current limit for normal output-off mode (this is the maximum current that flows between the two
SMUs when the output is off):
smua.source.offlimiti = 1e-3 -- default
Voltage compliance must be ten percent lower than the voltage compliance of SMU 1. This causes
SMU 1 to control the maximum voltage across the DUT. Voltage compliance limit (maximum):
smua.trigger.source.limitv = 18
