Source and measurement delays
Whenever the source-measure unit (SMU) outputs a source value in a sweep, it also applies the
programmed source delay. The default source delay is zero (0) seconds. Set an additional source
delay using the
smu
X
.source.delay
attribute.
Whenever the SMU performs a measurement in a sweep, it also applies any configured
measurement delays. Use the
smu
X
.measure.delay
attribute to program a specific measurement
delay. The default measurement delay varies by measure range.
Initiating and running sweeps
To run a sweep, you must configure the number of sweep points to output and the number of sweeps
to perform. See
(on page 3-32) for more information.
Examples:
To start a sweep, use the
smu
X
.trigger.initiate()
function. Sweeps are overlapped
operations, so you can use the
waitcomplete()
function as a way to suspend further operation
until the sweep is complete.
To sweep 15 source points:
smua.trigger.count = 15
To perform eight sweeps:
smua.trigger.arm.count = 8
Aborting a sweep
The
smu
X
.abort()
function can be used to terminate all overlapped operations on a
source-measure unit (SMU), including sweeps. It returns the SMU to the idle state of the remote
trigger model. See
(on page 3-32) for more information.
Sweeping using factory scripts
Factory script functions that perform linear staircase, logarithmic staircase, and list sweeps are listed
(on page 5-1). You can use the factory script functions to perform
and execute simple sweeps, or use them as examples for programming your own custom sweeps.
Front panel
To run a sweep from the front panel:
1. Press the
LOAD
key, and then select
FACTORY
.
2. Select the name of the test to run.
3. Press the
RUN
key, and then follow the display prompts to complete the test.
See
(on page 5-1) for more information about using factory scripts.
Press the
RECALL
key to access sweep data stored in dedicated reading buffer 1. See
(on page 3-6) for more details about the buffer.
