Keithley 2651A Reference Manual

Section 7: Command reference Model 2651A High Power System SourceMeter® Instrument Reference Manual
7-32 2651A-901-01 Rev. A / March 2011
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 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 volts
level
Pulse level in volts
limit
Voltage 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 (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 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 current measurements are stored in the reading buffer specified by the buffer input parameter.
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 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.
