KIGeneral TSP test script: ConfigPulseIMeasureVSweepLog
TSP project name: KIFactoryPulse
TSP test script name: KIPulse
Firmware version: 1.2.0 and later
Function:
ConfigPulseIMeasureVSweepLog
Usage:
f, msg = ConfigPulseIMeasureVSweepLog
(smu,bias,start,stop,limit,ton,toff,points,buffer,tag[,sync_in]
[,sync_out][,sync_in_timeout][,sync_in_abort])
Description
Configures a logarithmic pulsed current sweep with a voltage measurement at
each point. Measurement(s) will be made at the end of the ton time. The
magnitude of the first pulse will be start amps. The magnitude of the last pulse
will be stop amps. The magnitude of each pulse in between will be LogStep
n
amps larger than the previous pulse where:
LogStepSize =(log10(stop) - log10(start)) / (points -1)
LogStepn = (n - 1) x (LogStepSize) where n = [1, points]
SourceStepLeveln = antilog(LogStepn) x start
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 so, assigns the
indicated tag or index to it. The InitPulseTest(tag) and
InitPulseTestDual(tag) functions are used to initiate a pulse train assigned
to a valid tag.
Parameters
smu,bias,start,stop,limit,ton,toff,points,buffer,tag
[,sync_in][,sync_out])
smu: SourceMeter channel. (e.g. smua).
bias: Pulse bias level in amps.
start: Pulse sweep start level in amps.
stop: Pulse sweep stop level in amps.
limit: Voltage limit (i.e. compliance) in volts.
ton: Pulse width (i.e. 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. This parameter is optional.
sync_out: Defines a digital I/O trigger output line. If programmed, the
pulse train will generate a trigger output immediately prior
to the start of ton. This parameter is optional.
sync_in_timeout: Specifies the length of time (in seconds) to wait for input
trigger (defaults to 10s). New to Firmware 1.3.0
sync_in_abort: (true or false) Whether to abort pulse if input trigger is not
received before timeout expires (defaults to true). New to
Firmware 1.3.0
