Configure two 2600B SMUs to obtain the maximum pulsed voltage level possible in Region 4:
18 V with 19 A capacity
SMU 1 configuration (supplies additional current that SMU 2 alone cannot provide):
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):
smua.source.limitv = 6
Pulse source level (source level at top of pulse). Set the pulse source level ten percent lower than the
current source limit of SMU 2:
smua.trigger.source.listi({9})
Pulse source limit. SMU 1 voltage source limit must be greater than the maximum voltage supplied by
SMU 2. Set the voltage source limit of SMU 1 to the maximum voltage allowed in Region 4:
smua.trigger.source.limitv = 20
Output-off mode:
smua.source.offmode = smua.OUTPUT_NORMAL
Output-off function:
smua.source.offfunc = smua.OUTPUT_DCAMPS
Normal output-off voltage limit (40 V maximum):
smua.source.offlimitv = 20
