f
A Boolean flag; this flag is
true
when the pulse was successfully configured,
false
when
errors were encountered
msg
A string message; if the
f
flag is
false
,
msg
contains an error message; if it is
true
,
msg
contains a string indicating successful configuration
smu
System SourceMeter
®
instrument channel (set to
smua
)
bias
Bias level in volts
start
Pulse sweep start level in volts
stop
Pulse sweep stop level in volts
limit
Current limit (for example, compliance) in amperes
ton
Pulse on time in seconds
toff
Pulse off time in seconds
points
Number of pulse-measure cycles
buffer
Reading buffer where pulsed measurements will be stored; if this is
nil
when the function is
called, no measurements will be made when the pulse train is initiated
tag
Numeric identifier to be assigned to the defined pulse train
sync_in
Defines a digital I/O trigger input line; if programmed, the pulse train will wait for a trigger input
before executing each pulse
sync_out
Defines a digital I/O trigger output line; if programmed, the pulse train will generate a trigger
output immediately before the start of
ton
sync_in_timeout
Specifies the length of time (in seconds) to wait for input trigger; default value is 10 s
sync_in_abort
Specifies whether or not to abort pulse if input trigger is not received; if pulse aborts because
of a missed trigger, a timer timeout message is returned;
true
or
false
Details
Data for pulsed current measurements are stored in the reading buffer specified by the
buffer
input parameter.
This function configures a linear pulsed voltage sweep with a current measurement at each point. Measurements
are made at the end of the
ton
time.
The magnitude of the first pulse will be
start
volts; the magnitude of the last pulse will be
stop
volts. The
magnitude of each pulse in between will be
step
volts larger than the previous pulse, where:
step = (stop - start) / (points - 1)
