Additional hardware triggering parameters
New parameters added to the “Configure” functions after the sync_out parameter:
• *sync_in_timeout - specifies the length of time (in seconds) to wait for input trigger (defaults to 10s)
• *sync_in_abort - (true or false), whether to abort pulse if in put trigger is not received before
timeout expires (defaults to true)
• If pulse aborts due to missed trigger, message returned to the user indicates timer timeout.
NOTE *These parameters are new to firmware version 1.3.0.

KIGeneral TSP test script: ConfigPulseIMeasureV
TSP project name: KIFactoryPulse
TSP test script name: KIPulse
Firmware version: 1.2.0 and later
Function:
ConfigPulseIMeasureV
Usage:
f, msg = ConfigPulseIMeasureV
(smu,bias,level,limit,ton,toff,points,buffer,tag[,sync_in][,sync_out]
[,sync_in_timeout][,sync_in_abort])
Description
Configures a current pulse train with a voltage measurement at each point.
Measurement(s) will be 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 so, assigns the indicated tag or index to
the pulse train. The InitPulseTest(tag) and
InitPulseTestDual(tag) functions are used to initiate a pulse train assigned
to a valid tag.
Parameters
smu,bias,level,limit,ton,toff,points,buffer,tag[,sync_in]
[,sync_out]
smu: SourceMeter channel. (e.g. smua).
bias: Pulse bias level in amps.
level: Pulse 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
