configListName
The name of the source configuration list that the sweep uses; this must be defined
before sending this command
biasLevel
Output level the instrument sources before the first pulse and returns to between
pulses (delay and off time):
•
Current: -7.35 A to 7.35 A
•
Voltage: -105 V to 105 V
pulseLevel
The amplitude current or voltage from zero (not from the bias level):
•
Current: -10.5 A to 10.5 A
•
Voltage: -105 V to 105 V
pulseWidth
The time at the amplitude level for each pulse:
•
Extended operating area: 10 A at 100 V, 5 % duty cycle, maximum pulse
width: 1 ms, minimum pulse width 150 µs (load dependent)
•
Normal operating area (DC): 99.99 % duty cycle, maximum pulse width
10,000 s, minimum pulse width 150 µs
count
The number of pulses in the pulse train; default is
1
:
•
Infinite loop:
smu.INFINITE
•
Finite loop:
1
to
268435455
measEnable
Enable or disable measurements at the top of each pulse:
•
Enable:
smu.ON
(default)
•
Disable:
smu.OFF
bufferName
The name of the reading buffer, which may be a default buffer (
defbuffer1
or
defbuffer2
) or a user-defined buffer; defaults to
defbuffer1
sDelay
The amount of time that the instrument stays at bias level before each pulse (in
seconds): 0 to 10,000 s
offTime
The amount of time that the instrument stays at bias level after each pulse (in
seconds): 0 to 10,000 s
