f
A Boolean flag. This flag will be
true
when the pulse was successfully configured,
false
when errors were encountered
msg
A string message; if the
f
flag is
false
,
msg
will contain an error message; if it is
true
,
msg
will contain a string indicating successful configuration
smu
System SourceMeter
®
instrument channel (set to
smua
)
bias
Bias level in amperes
level
Pulse level in amperes
limit
Voltage limit (for example, compliance) in volts
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
(this parameter is optional)
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 voltage measurements are stored in the reading buffer specified by the
buffer
input parameter.
Configures a current pulse train with a voltage measurement at each point. Measurements are made at the end
of the
ton
time.
This function does not cause the specified
smu
to output a pulse train. It simply checks to see if all of the pulse
dimensions are achievable, and if they are, assigns the indicated
tag
or index to the pulse train. The
InitiatePulseTest(
tag
)
function is used to initiate a pulse train assigned to a valid
tag
.
