bufferVar.sourcevalues
When enabled by the bufferVar.collectsourcevalues attribute, this attribute contains the source levels
being output when readings in the reading buffer were acquired.
Type TSP-Link accessible
Attribute (R) Yes
Usage
sourcevalue = bufferVar.sourcevalues[N]
sourcevalue
bufferVar
N
Details
If the bufferVar.collectsourcevalues attribute is enabled before readings are taken, the
bufferVar.sourcevalues buffer recall attribute is like an array (a Lua table) of the sourced value
in effect at the time of the reading. Note that you can set the bufferVar.collectsourcevalues
attribute only if the affected reading buffer is empty. See
11-22) for more detailed information.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the
reading buffer is saved to nonvolatile memory.
Example 1
sourcevalue = smua.nvbuffer1.sourcevalues[1]
Example 2
printbuffer(1, 6, smua.nvbuffer1.sourcevalues) Print the sourced value of the first 6 readings
