stop
The voltage or current source level at which the pulse sweep stops:
•
Current: -10.5 A to 10.5 A
•
Voltage: -105 V to 105 V
points
The number of pulse-measure points between the start and stop values of the pulse
sweep (2 to 1e6)
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
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
count
The number of pulse sweeps; default is
1
:
•
Infinite loop:
smu.INFINITE
•
Finite loop:
1
to
268435455
xBiasLimit
The current or voltage limit for the defined bias level:
•
Current: 10 nA to 7.35 A
•
Voltage: 2 mV to 105 V
xPulseLimit
The current or voltage limit for the defined pulse level:
•
Current: 10 nA to 10.5 A
•
Voltage: 2 mV to 105 V
failAbort
Determines if the sweep is stopped immediately if a limit is exceeded; options are:
•
Abort the sweep if the source pulse limit is exceeded:
smu.ON
(default)
•
Complete the sweep if the source limit is exceeded:
smu.OFF
dual
Determines if the sweep runs from start to stop and then from stop to start:
•
Sweep from start to stop only:
smu.OFF
(default)
•
Sweep from start to stop, then stop to start:
smu.ON
asymptote
Default is 0; see

Details
Before configuring a pulse operation, configure your measure settings. Pulse operations use the
measure settings that were last defined before the pulse operation; you may get unexpected results if
you do not define the measure settings first.
When the pulse sweep is started, the instrument sources a specific voltage or current value to the
device under test (DUT). A measurement is made for each point of the pulse sweep.
When the pulse sweep command is sent, it clears the existing trigger model and creates a new trigger
model. To run the pulse sweep, initiate the trigger model.
The pulse sweep continues until the source outputs the specified stop level. At this level, the
instrument performs another measurement and then stops the pulse sweep.
When you specify a delay, a delay block is added to the pulse sweep trigger model.
