Model 2461 Interactive SourceMeter® Instrument Reference Manual
Section 6: SCPI command reference
2461-901-01 A/November 2015
6-111
<measEnable>
Enable or disable measurements at the top of each pulse:
•
Enable:
ON
(default)
•
Disable:
OFF
<bufferName>
A string that indicates the reading buffer; the default buffers (
defbuffer1
or
defbuffer2
) or the name of a user-defined buffer; if no buffer is specified,
defbuffer1
is used
<delay>
The amount of time that the instrument stays at bias level before each pulse (in
seconds): 0 to 10,000 s
<offTime>
The amount of time that the instrument stays at bias level after each pulse (in
seconds): 0 to 10,000 s
<count>
The number of pulse sweeps; default is
1
:
•
Infinite loop:
0
•
Finite loop:
1
to
268435455
<xBiasLimit>
The current or voltage limit for the defined bias level:
•
Current: 10 nA to 7.35 A
•
Voltage: 2 mV to 105 V
<xPulseLimit>
The current or voltage limit for the defined pulse level:
•
Current: 10 nA to 10.5 A
•
Voltage: 2 mV to 105 V
<failAbort>
Determines if the sweep is stopped immediately if a limit is exceeded; options are:
•
Abort the sweep if the source bias or pulse limit is exceeded:
ON
•
Complete the sweep if the source limit is exceeded:
OFF
<dual>
Determines if the sweep runs from start to stop and then from stop to start:
•
Sweep from start to stop only:
OFF
(default)
•
Sweep from start to stop, then stop to start:
ON
Details
Before configuring a pulse operation, configure your measure settings. Pulse operations use the
measure settings that were last defined before the pulse operation; you may get unexpected results if
you do not define the measure settings first.
When the pulse sweep is started, the instrument sources a specific voltage or current value to the
device under test (DUT). A pulse is output for each point of the sweep. If measurements are enabled,
a measurement is also made for each point of the sweep.
When the pulse sweep command is sent, it clears any existing trigger models, creates a source and
measure pulse configuration list, and populates the trigger model. To run the pulse sweep, initiate the
trigger model.
The pulse sweep continues until the source outputs the specified stop level. At this level, the
instrument performs another measurement and then stops the sweep.
When you specify a delay, a delay block is added to the pulse sweep trigger model.
This command updates a source configuration list named
CurrPulseLinearSweepList
or
VoltPulseLinearSweepList
, depending on the source function.
If measurements are enabled, this command creates a measure configuration list named
MeasCurrPulseLinearSweepList
or
MeasVoltPulseLinearSweepList
, depending on the
source function.
