Usage
sourcerange
=
bufferVar
.sourceranges[
N
]
sourcerange
The source range used 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 sourceranges buffer recall attribute is like an array (a Lua table) of full-scale range values for the source
range used when the measurement was made.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the reading buffer
is saved to nonvolatile memory.
Example 1
sourcerange = smua.nvbuffer1.sourceranges[1]
Store the source range that was used for the
first reading stored in dedicated reading
buffer 1.
Example 2
printbuffer(1, 6,
smua.nvbuffer1.sourceranges)
Print the source ranges that were used for the
first 6 readings stored in source-measure unit
(SMU) A, buffer 1.
Example output:
1.00000e-04, 1.00000e-04,
1.00000e-04, 1.00000e-04,
1.00000e-04, 1.00000e-04
