Reading buffers
bufferVar.sourcefunctions
This attribute contains the source function that was being used when the readings were stored in a specified
reading buffer.
Type TSP-Link accessible
Attribute (R) Yes
Usage
sourcefunction = bufferVar.sourcefunctions[N]
sourcefunction
bufferVar
N
Details
The sourcefunctions buffer recall attribute is like an array (a Lua table) of strings indicating the source
function at the time of the measurement.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the reading buffer
is saved to nonvolatile memory.
Example 1
sourcefunction = smua.nvbuffer1.sourcefunctions[3]
