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 Affected by Where saved Default value
Attribute (R) Yes Clearing the buffer See Details Not applicable
Usage
sourcefunction = bufferVar.sourcefunctions[N]
sourcefunction
The source function used ("current" or "voltage") to acquire reading number N
in the specified buffer
bufferVar
The reading buffer; can be a dynamically allocated buffer (user-defined), or a
dedicated reading buffer (such as smua.nvbuffer1)
N
The reading number (1 to 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]
Store the source function used
to make reading number 3.
Example 2
printbuffer(1, 10, smua.nvbuffer1.sourcefunctions)
Print the source function used
for 10 readings stored in
dedicated reading buffer 1.
Example output:
