Usage
:SOURce[1]:SWEep:<function>:LIST <startIndex>
:SOURce[1]:SWEep:<function>:LIST <startIndex>, <delay>
:SOURce[1]:SWEep:<function>:LIST <startIndex>, <delay>, <count>
:SOURce[1]:SWEep:<function>:LIST <startIndex>, <delay>, <count>, <failAbort>
:SOURce[1]:SWEep:<function>:LIST <startIndex>, <delay>, <count>, <failAbort>,
"<bufferName>"
:SOURce[1]:SWEep:<function>:LIST <startIndex>, <delay>, <count>, <failAbort>,
"<bufferName>", "<configListName>"
<function>
The source function:
• Current: CURRent
• Voltage:
VOLTage
<startIndex>
The index in the configuration list where the sweep starts; default is
1
<delay>
The delay between measurement points; default is 0 for no delay or you can set a
specific delay value from 50 µs to 10,000 s
<count>
The number of times to run the sweep; default is 1:
• Infinite loop: 0
• Finite loop:
1
to
268435455
<failAbort>
Determines if the sweep is stopped immediately if a limit is exceeded; options are:
• Abort the sweep if a limit is exceeded: ON
•
Complete the sweep even if a limit is exceeded: 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
<configListName>
The name of the source configuration list that the sweep uses; this must be defined
before sending this command
Details
This command allows you to set up a custom sweep, using a configuration list to specify the source
levels.
When you specify a delay, a delay block is added to the sweep trigger model. This delay is added to
any source delay you may have set. For example, if you set 10 ms for the source delay and 25 ms for
the delay in the for the log sweep command, the actual delay is 35 ms.
A configuration list must be created before you send this command. You can either use the
:SOURce[1]:LIST:<function> to set up the configuration list, or you can create your own
configuration list.
To run the sweep, initiate the trigger model.
