ConfigPulseVMeasureI()
This KIPulse factory script function configures a voltage pulse train with a current measurement at each point.
Type TSP-Link accessible
Affected by Where saved Default value
Function No
Usage
f, msg = ConfigPulseVMeasureI(smu, bias, level, limit, ton, toff, points, buffer,
tag, sync_in, sync_out, sync_in_timeout, sync_in_abort)
f, msg = ConfigPulseVMeasureI(smu, bias, level, limit, ton, toff, points, buffer,
tag, sync_in, sync_out, sync_in_timeout)
f, msg = ConfigPulseVMeasureI(smu, bias, level, limit, ton, toff, points, buffer,
tag, sync_in, sync_out)
f, msg = ConfigPulseVMeasureI(smu, bias, level, limit, ton, toff, points, buffer,
tag, sync_in)
f, msg = ConfigPulseVMeasureI(smu, bias, level, limit, ton, toff, points, buffer,
tag)
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
level
Pulse 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 waits for a trigger input
before executing each pulse
sync_out
Defines a digital I/O trigger output line; if programmed, the pulse train generates 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 voltage pulse train with a current 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 does check to see if all the pulse
dimensions can be achieved, and if they can, assigns the indicated tag or index to the pulse train.
